2 Wireless Reference Manual P1035089-003

2.1 Overview

ZXP Series 7 and ZXP Series 8 Card Printers have an internal print server that supports both wired and wireless Ethernet connectivity. The wired Ethernet capability is standard with the printer while the wireless capability is an option that can be ordered as a factory-installed printer option. The wireless option is field upgradeable by a Zebra-authorized field technician, but requires partial disassembly of the printer to remove the wired daughter card and replace it with a wired/wireless daughter card (see separate document that describes daughter card installation in the printer).

Networking Basics

The printer supports simultaneous wired and wireless connections, a capability referred to as multi-homing, in this case having two separate interfaces with separate IP addresses. To connect to a wireless network, the printer uses wireless protocol IEEE 802.11b/g that communicates data through radio transmission. After installing the printer to a wireless network, cables are not required to communicate with the computers or devices that are part of the network.

A wireless local area network (WLAN) is a collection of two or more computers, printers, and other devices linked by radio waves. A WLAN uses high-frequency airwaves (radio) to communicate information from one point to another.

To connect a computer or device to a wireless network, the computer or device must have a wireless network adapter. The Printer uses an internal networking component that contains a wireless radio. No cabling is necessary between networked devices that use wireless technology, although it is possible to use a USB or wired Ethernet cable to configure your printer for a wireless network.

P1035089-003 Wireless Reference Manual 3

2: Networking Basics

Channels and communication modes

2.2 Channels and communication modes

The band of radio signals used for IEEE 802.11b/g wireless networking is segmented into specific frequencies, or channels. For IEEE 802.11b/g wireless networks, 13 channels are available. Each country/region specifies the channels that are authorized for use. For example, in North America, only channels 1 through 11 are allowed. In Japan, channels 1 through 14 can be used (channel 14 – 802.11b only). In most of Europe, channels 1 through 13 are allowed. Because existing standards change frequently, you should check with your local regulatory agencies for authorized channel use. In most countries/regions channels 10 and 11 may be used without restriction.

Channel selection depends on the communication mode of the network. The communication mode defines how devices (i.e., computers and printers) communicate on a wireless network.

There are two primary types of wireless communication modes: infrastructure and ad-hoc.

• In infrastructure mode, the printer communicates with network computers through a wireless access point (AP) or a base station. The access point acts as a central hub or gateway connecting wireless and, optionally, wired devices (most access points have integrated Ethernet controller to connect to an existing wired-Ethernet network).

• In the ad-hoc mode, which is sometimes called peer-to-peer mode, the printer communicates with your computer directly, rather than through an access point or base station. Each device on an ad-hoc network must have a wireless network adapter. The adapter enables each device to communicate with the other devices on the network. Ad-hoc mode is usually limited to simple, small wireless networks because performance degrades significantly after connecting too many network devices. This option is most often used if you are connecting only two network devices that are not sharing an Internet connection. Only WEP security is available in ad-hoc mode.

4 Wireless Reference Manual P1035089-003

2.3 Security

As with other networks, security for wireless networks focuses on access control and privacy. Traditional wireless network security includes the use of Service Set Identifiers (SSIDs), open or shared-key authentication and static Wired Equivalent Privacy (WEP) keys or WiFi protected access (WPA or WPA2).

It is highly recommended that you implement a wireless security scheme (preferably WPA2) prior to setup. While the printer can connect to an open AP, running an open wireless AP may allow anyone within range of the AP full access to all devices connected to the AP with potentially damaging results. While WEP security is still in use today, WEP security has been broken for many years. There are tools available on the Internet that will allow anyone with even basic networking knowledge to break the WEP security and derive the WEP key within 3 minutes, giving them full access to devices on your network. The best security is obtained by using WPA2 security with CCMP/AES encryption.

Authentication and encryption are two different mechanisms to network security. Authentication verifies the identity of a user or device before granting access to the network, making it more difficult for unauthorized users to access network resources. Encryption encodes the data being sent across the network, making the data unintelligible to unauthorized users. Both of these mechanisms are on wireless networks.

2: Networking Basics

Security

2.4 Authentication

The Printer supports Open System authentication. A network with Open System authentication does not screen network users based on their identities and usually involves supplying the correct SSID. Such a network might use Wired Equivalent Privacy (WEP) encryption to provide a first level of security, or WiFi protected access (WPA/WPA2) to provide security by encrypting data sent over radio waves from one wireless device to another wireless device. The printer allows for WEP, WPA or WPA2.

2.5 Network name (SSID)

Wireless devices are configured with the name of the network to which they will connect. The network name is also called the SSID and identifies the ESS (Extended Service Set) that is normally associated with larger infrastructure networks. The SSID should not be considered a security feature because it can be easily identified. However, as a network administration or management feature, it does provide basic network access control.

It is common practice to setup access points such that the SSID is not broadcast (i.e., hidden invisible). The printer can connect to invisible access points, although the user must know

or SSID name and correctly enter it into the printer. There is a belief that hiding the SSID

the adds extra security to the network. This is, in fact, false as a device connecting to a network must send the SSID in the clear and the SSID can be easily obtained from the association management frame. Hiding the SSID makes it more error prone to connect to a network.

P1035089-003 Wireless Reference Manual 5

2: Networking Basics

Encryption

2.6 Encryption

To reduce your network exposure to eavesdropping, establish a wireless security key for your network. The printer supports the WEP RC4 encryption, WPA TKIP encryption and WPA2 CCMP encryption (a form of AES encryption), which hinders unauthorized users from accessing data transmitted over the radio waves. For WEP, a single static WEP key (40 or bits) is installed in the printer. Each computer or device is configured with the same key

104 communicate on that network. The most secure encryption is achieved using WPA2

to CCMP.

with

WPA and WPA2 security provides the means to deploy dynamic encryption keys to devices on the network. There are two approaches that are used for key deployment which are usually referred to as Personal and Enterprise. In the Personal mode, a Pre-Shared Key (PSK) is deployed on each network access point and device. The PSK is then used to derive Transient Keys which are used between an access point and the devices which are connected to it. In the Enterprise mode, an authentication server is used to deploy keys using one of several available Extensible Authentication Protocols (EAP).

For WPA or WPA2 Personal, a single, 8 – 63 character passphrase is entered into the access point. The same passphrase must be entered into the printer. The access point and printer each derive the same 32 byte PSK from the passphrase using the password-based key derivation function 2 (PBKDF2) from RFC 2898. The importance of picking a secure passphrase cannot be overstressed. The most prevalent security attack against WPA-PSK is a brute force dictionary attack, using a list of common words to “guess” your passphrase. So a passphrase like “darthvader” could result in your security being quickly compromised.

When constructing your passphrase, keep the following suggestions in mind:

• Use more than 8 characters. The more characters, the more secure.

• Use a combination of uppercase, lower case, numeric and punctuation characters.

• Use random characters, avoid using recognizable words from any language.

2.7 Media access control address authentication

Some WLAN vendors support authentication based on the physical address, or MAC address, of the client Network Interface Card (NIC). In this scenario, an access point allows association by a client only if that client’s MAC address matches an address in an authentication table used by the access point. This is not configurable through the printer.

Installing the Printer

Important • Only use the antenna that is shipped with the printer to ensure regulatory

compliance for the transmit power.

The printer with the wireless option ships with the wireless radio installed in the printer. An antenna is shipped in the box with the printer. The antenna must be connected to the rear of the printer before using the wireless interface. Lightly push the antenna onto the printer antenna connector and rotate the knurled antenna connector until finger tight.

The antenna used for this transmitter must be installed to provide a separation distance of at least 20 cm (8 inches) from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter during use the antenna is no closer than 20 cm to the body of any persons in the area of the printer and that the during normal use of the printer the distance is maintained. The antennas for any other transmitters should be separated from the printer antenna by at least 20 cm. This is required for RF exposure compliance.

The antenna orientation is important to maximize the wireless signal strength. Inspect the access point antenna(s) and try to put the printer antenna in a similar orientation. connecting the printer to the wireless network, the antenna orientation can be adjusted to maximize signal strength.

Decreasing signal strength results in automatic data rate reduction. At the longest distance, network traffic can become very slow.

As the distance between the printer and the access point increases, the signal strength

Printer location is important to ensure that adequate signal strength is achieved. Follow these suggestions:

• Position the printer as close to the access point that it will connect to as possible.

• If possible, orient the printer such that there is a clear line of sight between the printer antenna and the access point antenna.

• Locate the printer such that there are no intervening walls in the line of sight antennas.

Configuring the Printer

4.1 Overview

To set up the printer for wireless printing, you need to know:

• The name of your wireless network, also known as the Service Set Identifier (SSID).

• If encryption was used to secure your network.

• The security key (WEP key, WPA passphrase, or hex key) that allows other devices to communicate on the network if encryption was used to secure your network.

• If the access point you will connect to doesn’t broadcast the SSID, you will need to know the BSSID (MAC Address of the wireless interface) for the AP. Make sure that you have the correct MAC address, your AP may have several.

If your wireless access point is using Wired Equivalent Privacy (WEP) security, the WEP key should be exactly 10 or 26 hexadecimal characters. Hexadecimal characters are A–F, a–f, 0–9.

and

If your wireless access point is using WiFi Protected Access (WPA or WPA2) security, the WPA passphrase should be from 8 to 63 ASCII characters. ASCII characters in a WPA passphrase are case-sensitive.

If your wireless network is not using security, then you will not need a security key. Using a wireless network with no security is not recommended because it can allow intruders to use your network resources without your consent. Intruders could then read and decode your transmissions with readily available tools found on the Internet.

Note • Make sure you copy down the security key and SSID exactly, including any capital

letters, and store it in a safe place for future reference. If you do not know the SSID of the network that your computer is connected to, launch the wireless utility of the computer network adapter and look for the network name. If you cannot find the SSID or the security information for your network, see the documentation that came with the wireless access point, or contact your network support person.

There are three ways to configure the printer to connect to a wireless network:

• Configure the printer through the printers Web Page using wired Ethernet; refer to

Section 4.4 on page 12 for details.

• Configure the printer through the Windows Printer Driver Toolbox using USB or wired Ethernet; refer to Section 4.5 on page 16 for details.

• Configure the printer through the Operator Control Panel.; refer to Section 4.6 on page 21 for details.

10 Wireless Reference Manual P1035089-003

4.3 Network Settings

Every device connected to an Ethernet network must be assigned an IP Address, Subnet Mask and Default Gateway Address. An IPv4 Address consists of a 32-bit binary number, which is typically presented as four decimal numbers (one for each 8-bit byte) separated by decimal points (for example: 192.168.0.100). The subnet mask determines what subnet an IP address belongs to. A typical subnet would be 255.255.255.0. As applied to the previous example, devices with IP Addresses in the range of 192.168.0.1 through 192.168.0.255 would all be in the same subnet. The default gateway is the node connecting the internal networks and the outside network (Internet).

In order to configure the printer, these settings must be known or DHCP must be used to automatically configure the printer. If the network has a DHCP server, the printer can request the network settings from the DHCP server after establishing a connection to the access point. Otherwise, these settings must be known and manually entered into the printer. Check with your network administrator if you are not sure about whether to use DHCP or manual settings.

When using DHCP, be aware that the DHCP server may periodically change the IP Address assigned to the printer. If this happens, the Windows Printer Driver may no longer be able to communicate with the printer. To prevent this, DHCP servers can be configured to lock an IP Address to a specific MAC address. Obtain the wireless MAC address from the Operator Control Panel (make sure you get the correct MAC Address, there are two, one for wired and one for wireless) and use this to configure the DHCP server. Some DHCP servers are configured to reject DHCP requests from unknown devices. Again, the MAC address can be used to configure the DHCP server or access point to recognize the printer.

4: Configuring the Printer

Network Settings

If you plan to use both wired and wireless Ethernet interfaces at the same time, see the “Multihoming Considerations” section. The configuration of the IP Address and Subnet Mask on each interface must be set correctly depending upon whether the two interfaces are connected to the same network or totally separate networks. Improperly configured network settings may result in a communications failure.

Check the Status section. If the connection succeeded, the State parameter should be “connected”. If the State is “inactive”, then the connection failed, probably due to the WPA/ WPA2 passphrase being incorrect. If the State is “scanning”, then the access point wasn’t found and periodic scans are underway to find the access point. This may mean that the SSID or BSSID was entered incorrectly. If you are connecting with WEP security, the only way to know that the WEP key is correct is to try to communicate with the printer through the wireless interface. If the communication fails then it is likely the WEP key was entered wrong.

You can then see the IP Address, Subnet Mask, and Default Gateway the computer is configured to use. It is likely that you can use the same Subnet Mask and Gateway settings in your printer. You will need to use a different and unused IP Address. To verify that the one you plan to use is available, type “ping xx.xx.xx.xx” at the command prompt where xx.xx.xx.xx is the IP Address you plan to use. If the ping times out, that means that no device on the network with that IP Address responded.

Simple Roaming Used During Connection

4.10 Simple Roaming Used During Connection

While the printer does not support full roaming such as might be available in a mobile wireless device such as an iPhone, the printer does support a limited roaming capability during connection. When the printer tries to establish a connection to an access point, it takes the following steps until connection is established:

1. Scan for the configured access point (using both SSID and BSSID) on the configured

channel. If no access point found, proceed to step 2. If found, connection is attempted. If connection successful, proceed to step 6 (done). If connection fails, proceed to step 3.

2. Scan for the configured access point (using both SSID and BSSID) on all channels. If no

access point found, proceed to step 3. If found, connection is attempted. If connection successful, proceed to step 6 (done). If connection fails, proceed to step 3.

3. Scan for all access points with the correct SSID (BSSID ignored) that have the identical

security settings as the configured access point on all channels. If no access point found, proceed to step 5. If multiple access points found, connection is attempted on access point with best signal strength. If connection successful, proceed to step 6 (done). If connection fails, proceed to step 4. If single access point found, connection is attempted. If connection successful, proceed to step 6 (done). If connection fails, proceed to step 5.

4. Delete access point to which connection failed in step 3. If another access point with

correct SSID and correct security settings is available, go to step 3. Otherwise, go

the step 5.

5. Exhausted all connection attempt, delay for 5 seconds, then go to step 1.

6. Connection succeeded, done.

This approach will handle the following conditions:

• Configured access point can’t be reached (power is off).

• Configured access point can’t accept another station (load balancing is forcing the printer to connect to a different access point).

Setting Up an Ad-Hoc ( Peer ) Network

4.11 Setting Up an Ad-Hoc ( Peer ) Network

On wireless computer networks, ad-hoc mode is a method for wireless devices to directly communicate with each other. Operating in ad-hoc mode allows all wireless devices within range of each other to discover and communicate in peer-to-peer fashion without using access points. To set up an ad-hoc wireless network, each wireless adapter must be configured for adhoc mode versus the alternative infrastructure mode. In addition, all wireless adapters on the ad-hoc network must use the same SSID and the same channel number. An ad-hoc network tends to feature a small group of devices all in very close proximity to each other. Performance suffers as the number of devices grows, and a large ad-hoc network quickly becomes difficult to manage.

WiFi devices in ad-hoc mode offer minimal security against unwanted incoming connections. Only WEP security is available in the ad-hoc mode. Ad-hoc WiFi devices cannot disable SSID broadcast like infrastructure mode devices can. Attackers generally will have little difficulty connecting to an ad-hoc device if they get within signal range.

The security hole provided by ad-hoc networking is not the ad-hoc network itself but the bridge it provides into other networks, usually in the corporate environment. If a computer using an ad-hoc connection is also using a wired or wireless infrastructure network at the same time, it is providing a bridge to the secured organizational network through the unsecured Adhoc connection. Bridging is in two forms. A direct bridge requires the configuration of a bridge between the two connections and is thus unlikely to be initiated unless explicitly desired. An indirect bridge is the shared resources on the computer. The indirect bridge provides two security hazards. The first is that critical organizational data obtained via the secured network may be on the computer drive and thus exposed to discovery via the unsecured Ad-hoc network. The second is that a computer virus or otherwise undesirable code may be placed on the computer via the unsecured ad-hoc connection and thus has a route to the organizational secured network. In this case, the person placing the malicious code need not “crack” the passwords to the organizational network, the legitimate user has provided access via a normal and routine log-in. The malefactor simply needs to place the malicious code on the unsuspecting user's end node system via the open (unsecured) ad-hoc connection.

Setting Up an Ad-Hoc ( Peer ) Network

The WiFi networking standards (including 802.11g) require only that ad-hoc mode communication supports a maximum of 11 Mbps bandwidth. You should expect that WiFi devices supporting 54 Mbps or higher in infrastructure mode, will drop back to a maximum of 11 Mbps when changed to ad-hoc mode. Ad-hoc mode should generally be viewed as “slower” than infrastructure mode for this reason. Some wireless cards can be configured to provide 54 Mbps operation in ad-hoc mode. If this is desirable, all peers that will join the ad-hoc network must be configured for 802.11g 54 Mbps. To configure this using Windows XP:

1. Open the Network Connections windows.

2. Right click the wireless network connection and select Properties.

3. At the top of the dialog, click Configure.

4. Click the Advanced tab.

5. Under Property, look for the appropriate setting, like IBSS Mode.

6. Select the desired Value and click OK.

In order to establish the ad-hoc network with the Printer for the first time, you must setup the ad-hoc network on a computer first with a wireless adapter then connect the printer to the adhoc network. Once the printer has successfully connected to the ad-hoc network, it will save the necessary parameters to re-connect to the same network the next time the printer is powered on. If the ad-hoc network is not found when powered on, the printer will establish the ad-hoc network with the same settings used when first connected to the ad-hoc network. A computer can then connect to the ad-hoc network at a later time and access the printer. Once the printer has been connected to the ad-hoc network, the order that the printer and computers are powered on doesn’t matter. The printer will only look for the ad-hoc network or establish an ad-hoc network on the same channel as the ad-hoc network that the printer was first connected to.

Before establishing an ad-hoc network, you will need to establish IP Addresses and Subnet Mask for the computers and printer. It is likely that a DHCP server will be unavailable. The computers may power up and assign themselves Automatic Private IP Addresses in the range of 169.254.0.0 to 169.254.255.255 if a DHCP server is unreachable. If this is the case, then you will need to disable DHCP in the printer and assign an unused static IP Address to the printer that is within this range and set the printer Subnet mask to 255.255.0.0. A better approach would be to assign static IP addresses to the printer and all the computers that will be part of the ad-hoc network. IP addresses in the range 192.168.0.0 to 192.168.0.255 with a Subnet Mask of 255.255.255.0 are often used for this purpose. Remember that each device must have a unique IP address and common Subnet Mask.

Be careful about the computer IP Address and Subnet Mask that the wired Ethernet connection is using. If the computer wired IP address is on the same Subnet as the wireless interface (i.e., both are using a 192.168.0.X IP Address with Subnet Mask of 255.255.255.0) then communications over the wireless interface may fail because the Ethernet packets intended for the wireless interface may be routed through the wired interface. This issue can be addressed by disabling the computer wired interface or assigning a static IP Address to the wireless interface that puts it on a different Subnet than the wired interface.

38 Wireless Reference Manual P1035089-003

4: Configuring the Printer

Setting Up an Ad-Hoc ( Peer ) Network

If you plan to use both wired and wireless Ethernet printer interfaces at the same time, see the “Multi-homing Considerations” section. The configuration of the IP Address and Subnet Mask on each printer interface must be set correctly depending upon whether the two interfaces are connected to the same network or totally separate networks. Improperly configured network settings may result in a communications failure.

Instructions for establishing an ad-hoc network on a computer or laptop may vary between OS versions and wireless adaptors. The following steps are generic but should be helpful for getting started:

1. There is usually a wireless icon in the task bar which can be used to access a wireless

Setup Utility. Right click on the icon and open the Utility.

2. Add an ad-hoc network. There may be an Add button you can click, followed by clicking

on “Create an ad hoc network”.

3. You should be presented with a dialog to enter the SSID or network name. The name can

be 1 – 32 text characters. Pick a name that is meaningful and easy to remember. Write it down! Click Next.

4. You should now enter a dialog for Security and Channel selection. The security choices

are: None or WEP. It is highly recommended that you choose WEP. While WEP security is poor, it is better than none. Try to pick a channel that is quiet or not heavily used. Your Setup Utility may offer Site Management and Congestion analysis that will help you pick the best channel. Once the selections have been made click Next.

5. If you selected WEP security, you will now need to enter the WEP key. You can enter

either a 40 bit key (10 Hex characters) or a 104 bit key (26 Hex characters). Save the key, you will need to use it when you connect the printer to the wireless network. Click Next.

6. Now click Connect to establish the ad-hoc network. Nothing exciting happens as the

network has no peers as yet. No signal strength will be shown.

Once you have created the ad-hoc network, power on your printer and follow the same instructions as detailed above in the “Configure the Printer through the Operator Control Panel” section.

P1035089-003 Wireless Reference Manual 39

4: Configuring the Printer

Setting Up an Ad-Hoc ( Peer ) Network

After scanning is complete and you are scrolling through the access points, you will notice that ad-hoc networks are announced by replacing “MAC:xx.xx.xx.xx.xx.xx” with “ADH:xx.xx.xx.xx.xx.xx” as shown below:

Once you have selected the ad-hoc network, selected the WEP key size, entered the WEP key and pressed connect, the printer should connect to the ad-hoc network. The computer wireless antenna icon should show signal bars. The printer OCP should also show a solid antenna icon. When there are more peers connected to the ad-hoc network than just the printer, the printer will also turn on an additional OCP icon that looks like a folder:

SSID: Test ADH:00:a0:f8:be:fe:72 Chan = 1 SIG = 52% SEC MODE: WEP CRYPTO: RC4

MAX SPEED: 54 Mbps

NEXT SELECT CANCEL

The folder icon is useful to determine whether another peer is connected to the same ad-hoc network as the printer. When using the OCP Info display to see the Wireless Info, an ad-hoc connection will display as follows:

4.12 Multi-homing Considerations

The printer has both wired and wireless Ethernet interfaces that can be used at the same time. This capability is referred to as multi-homing, where a device has multiple interfaces with a different IP address assigned to each interface. If you intend to use this capability, care must be taken with regard to the IP addresses assigned and whether both interfaces connect to the same network or different networks. If instead you intend to use only one interface then the remainder of this section doesn’t apply. It is recommended, however, that if you plan to use only the wireless interface that you disable DHCP on the wired interface and set the wired interface network settings (IP Address, Subnet Mask and Gateway Address) to a different subnet than the one the wireless interface is using. This can be as simple as setting the wired interface IP Address to: 0.0.0.0. This will prevent a wireless interface communications error if the wired interface is plugged into a network.

The primary multi-homing issue depends upon whether both wired and wireless interfaces are configured for the same subnet. For example, if both interfaces are configured with a Subnet Mask of 255.255.255.0, the wired interface IP Address is set to 192.168.0.11 and the wireless interface IP Address is set to 192.168.0.47, both interfaces are on the same subnet. The Subnet Mask determines the span of the subnet. In this case, any IP Address in the range of

192.168.0.0 to 192.168.0.255 falls within the same subnet. If the wired interface IP Address was changed to 192.168.1.11, the interfaces would be on different subnets. If the Subnet Mask was changed to 255.255.0.0 for both interfaces, then both interfaces would be on the same subnet again and the IP Address range for that subnet would be 192.168.0.0 to

192.168.255.255.

4: Configuring the Printer

Multi-homing Considerations

When both wired and wireless interfaces are configured for the same subnet and connected to a network, the printer can no longer distinguish between the two interfaces when routing Ethernet packets to the network. While packets are received on both interfaces, packets that are being routed to the network are likely to be returned on the wired interface. This is the routing algorithm will look for the first interface available that satisfies the

because requirements based upon the destination IP Address. Given this, both interfaces must

routing connect to the same network so that any host that sends packets to the printer is reachable on both interfaces.

There may be occasions where it is desirable to connect the printer to two entirely separate networks. In this scenario, the hosts on one network are not reachable through the other network. To make this work correctly, the two networks must be on different subnets. The IP Address and Subnet Mask settings must be properly set to achieve this. For example, if both interfaces are configured with a Subnet Mask of 255.255.255.0, the wired interface IP Address is set to 192.168.0.11 and the wireless interface IP Address is set to 192.168.1.47, both interfaces are on different subnets.

If the configuration of the printer network settings is not done correctly, communications may fail due to packets being sent on the wrong interface. When configured for different subnets, the printer does not provide a bridge between the two networks.

5: Monitor Wireless Performance

Signal Strength

5.3 Signal Strength

In addition to the signal strength value available on the Wireless Info screen, the printer also uses an antenna icon on the OCP to indicate signal strength. The antenna icon has a body and four bars associated with it. Thus five separate icon states are available from no bars (just icon body) to four bars. The signal strength is based upon the SNR (Signal to Noise Ratio) with which data packets are being received by the radio. The SNR is translated into a percentage in order to make the number more intelligible to the user. For those that are interested, the SNR can be derived from the signal strength in percent by using this equation:

SNR (dB) = 40 * Signal Strength (%) / 100

The following table outlines the SNR bands that are used to determine how many bars to display for the antenna icon:

SNR (dB) Bars Signal

Strength %

40 and above 4 100 Robust connection, always fast.

25 to 39.99 3 62 - 99 Robust connection, mostly fast.

0 to 4.99 0 0 - 11 Insufficient signal to connect.

0 - blinking Connection in progress.

Quality

intermittent loss of link.

It is very important to recognize that good signal strength is absolutely necessary for reliable operation. Signal strength below 25% is likely to cause problems. Signal strength above 50% will provide robust operation. Signal strength is not merely a factor of the distance between the printer antenna and the access point antenna. Other factors such as ambient noise, intervening walls and other nearby wireless equipment can result in poor signal strength. See the Troubleshooting chapter for suggestions for improving signal strength.

46 Wireless Reference Manual P1035089-003

5.4 Noise Floor

The noise floor is an instantaneous measure of the ambient noise that the wireless radio sees when it is not transmitting or receiving a packet. There is always ambient thermal noise near a level of -100 dBm that cannot be avoided. Added to this is man-made noise coming from: microwave ovens, cordless telephones, baby monitors, wireless cameras, remote car starters, DECT and residential wireless phones and Bluetooth products to name just a few. When you add the noise sources together, the typical noise floor the wireless radio should see is approximately -90 ±5 dBm. A more negative number is better (-95 is less noise than -90). The noise floor value can be useful to evaluate whether the ambient noise is too high for robust wireless operation. If the noise floor is higher than -85 dBm, then you may want to take steps to reduce the noise level the wireless radio sees (see the Troubleshooting chapter). By using the Signal Strength and Noise Floor values, the actual signal level can be calculated as follows:

Signal Level (dBm) = Noise Floor (dBm) + (40 * Signal Strength (%) / 100)

5.5 Data Rate

5: Monitor Wireless Performance

Noise Floor

The data rate shown in the Wireless Info display can provide some insight into how well the wireless interface is working. When there is a good SNR, the radio should typically show the maximum data rate the access point can support (11 Mbps for 802.11b and 54 Mbps for

802.11g). You may notice at times that lower speeds are displayed. This is expected as long as the maximum speed appears most of the time, particularly when a print job is being received. When the SNR is poor, data will be sent at a slower speed to improve the signal quality (receiver sensitivity is better at slower data rates). If you consistently see a low data rate, then you may want to take steps to improve the signal quality; see

The RX Bytes value is the total number of bytes that have been received by the printer via its radio. The number of discards represents the number of RX packets that were discarded because there was no buffer available to receive the packet. This should almost always be zero. A discard is not a hard failure as the packet will be resent by the sender at a later time. The TX Bytes value is the total number of bytes that have been sent by the printer to the radio. The number of discards represents the number of TX packets that were discarded because the packet was malformed or dropped due to a communication error with the radio. This should almost always be zero. A discard is not a hard failure as the packet will be resent by the printer at a later time. The final value is a catchall error counter for errors. This should be zero as it indicates a hard error. A non-zero error counter may mean that there is a hardware failure. The wireless statistics counts are reset to zero on power-up.

6.2 Wireless Troubleshooting Checklist

Before beginning to troubleshoot the wireless printer, verify the following:

• The power cord is connected to the printer, and the printer is on.

• The antenna is attached to the printer, and the polarity of the antenna matches that of the access point.

• Your SSID is correct. If you are not sure if your SSID is correct, run the wireless setup wizard again.

• Your WEP key or WPA passphrase is correct. Log into the wireless access point and check the security settings. A security key is like a password. All devices on the same wireless network using WEP, WPA, or WPA2 share the same security key. If you are not sure if your security information is correct, run the wireless setup wizard again.

• The wireless network is working properly. Try accessing other computers on your wireless network. If your network has Internet access, try connecting to the Internet over a wireless connection.

• The printer is within the range of the wireless network. For most networks, the printer should be within 100 feet (30 meters) of the wireless access point.

• The printer is located away from obstacles that could block the wireless signal. Remove any large metal objects between the access point and the printer. Make sure the printer and wireless access point are not separated by poles, walls, or support columns containing metal or concrete.

• The printer is located away from other electronic devices that may interfere with the wireless signal. Many devices can interfere with the wireless signal, including microwave ovens, baby monitors, motors, cordless phones, security system cameras, other wireless networks, and some Bluetooth devices.

• The printer driver is installed on the computer from which you are performing a task.

• The correct printer port is selected.

• The computer and printer are both connected to the same wireless network.

• If there are other computers or resources on your wireless network, check to see if you can access them from your computer.

2. Move the Computer and/or Printer Closer To the Wireless Access Point

Although the possible distance between devices in 802.11b or 802.11g networks is 300 feet, the maximum range for optimal performance is generally 100–150 feet.

a. Click Start.

b. Click All Programs or Programs->Accessories->Command Prompt.

c. Type ipconfig.

d. Press Enter.

e. The “Default Gateway” entry is typically the wireless access point. The IP address

appears as four sets of numbers separated by periods, such as 192.168.0.100. Your IP address might also start with the numbers 10 or 169. This is determined by your operating system or wireless network software.

5. Check Your Security Keys

A security key is like a password. All devices on the same wireless network must share the same security key.

• WEP key: Exactly 10 or 26 hexadecimal characters. Hexadecimal characters are A-F, a-f, and 0-9.

• WPA or WPA2 passphrase: From 8 to 63 ASCII characters. ASCII characters in a

WPA passphrase are case-sensitive. The currently recommended minimum length for a passphrase is twenty characters.

Note: If you do not know this information, see the documentation that came with the wireless network, or contact the person who set up your wireless network.

6. Check Your Advanced Security Settings

• If you are using MAC address filtering to limit access to your wireless network, you

must add the printer MAC address to the list of addresses allowed to connect to the wireless access point.

• If you set the wireless access point to issue a limited number of IP addresses, you

must change this so that the printer can be added.

Note: If you do not know how to make these changes, see the documentation that came with the wireless network, or contact the person who set up your wireless network.

7. Ping the Access Point to Make Sure the Network Is Working

If you do not already know it, find the IP address of the access point.

a. Click Start.

b. Click All Programs or Programs ->Accessories->Command Prompt.

c. Type ping followed by a space and the IP address of the wireless access point. For

example: ping 192.168.0.100

d. Press Enter.

e. Check to see whether the access point responds:

• If the access point responds, you will see several lines appear that start with “Reply from.” It is possible that the printer did not connect to the wireless network. Turn off and then restart the printer to try to connect again.

• If the access point does not respond, it will take several seconds and then you will see “Request timed out.” You will need to take steps to repair the connection between the PC and the wireless network.

8. Ping the Printer to See if it is Accessible

Use the INFO and NEXT soft-keys on the OCP to display the wireless IP Address. As shown above, print the printer with this address. If a timeout results, then the printer is not connected to the wireless network.

6.4 Improve Wireless Signal Strength

A common reason wireless printers fail to communicate over a network is poor wireless signal quality. If the signal is too weak, too distorted, or blocked by an object, it cannot carry information between the access point and the printer. To determine if the printer is receiving a strong signal from the access point, Use the INFO and NEXT soft-keys on the OCP to display to display the Wireless Info pages and Statistics. The Signal Strength and Noise Floor values may indicate poor signal strength or noisy environment. Drops in signal strength can be intermittent, however, and although the signal quality appears high, it may drop during certain conditions.

If you think signal strength is a problem between your access point and the printer, try one or more of the following:

1. Move the Printer Closer to the Wireless Access Point

If the printer is too far away from the access point, it will not be able to communicate with other devices on the network. For most indoor wireless networks, the maximum distance between the access point and the printer is approximately 100 feet (30 meters). This distance could be longer or shorter, depending upon the layout of the network and the limitations of the access point.

6: Troubleshooting

Improve Wireless Signal Strength

2. Remove Obstacles between the Access Point and the Printer

The wireless signal from your access point will pass through most objects. Most walls, floors, furniture and other objects will not block the wireless signal. However, there are materials that are too dense for the signal to pass through. Objects containing metal and concrete can block the signal, including:

• Cubicle walls

• Ducts

• Window frames

• Poles and interior support columns

• Metal office furniture and cabinets

• Elevators

• Steel doors

• Walls and other structural elements reinforced by rebar

Arrange your printer and access point so that the signal is not blocked by any of objects.

3. Remove Sources of Interference

Other types of radio frequencies can cause problems with the wireless signal on your network. These sources of interference can cause printing issues that seem to come and go. Some common sources of interference are:

• Microwave ovens

• Cordless phones

• Refrigerators and other appliances

• Bluetooth devices

• Other wireless networks

• Motors

Turn off these potential sources of interference where possible. Avoid using microwaves and cordless phones when printing over your wireless network.

If another wireless network is operating in the vicinity, change the wireless channel on access point.

4. Arrange the Network to Reduce Signal Absorption

Even when the wireless signal is able to pass through an object, it is slightly weakened. it passes through too many objects, it can be significantly weakened. All objects absorb

If part of the wireless signal when it passes through them, but certain types of objects absorb enough to cause communications problems. To avoid signal absorption, avoid placing the following items between your access point and your printer:

• Multiple walls or floors

• Stacks of paper or books

• Crowds of people

• Objects containing water, such as fish tanks

• Plants

Place your access point as high in the room as possible to avoid signal absorption.

5. Add an Additional Access Point

If the access point is too far away from the printer or the current access point has too wireless clients attached to it, try adding a second wireless access point to your

many network that is closer to the printer. Make sure that you use different channels for the access points. Note that 1, 6, and 11 are the preferred channel choices (in the

two States).

6. Conduct Site Survey

The location of your wireless network may have too many access points within range of the printer. Access points on the same or adjacent channels can interfere with each other, causing reduced signal strength, retries and corrupted packets.

To find out about the access points in the area, use a tool such a NetStumbler or InSSIDer. NetStumbler (also known as Network Stumbler) is a tool that facilitates detection of Wireless LANs using the 802.11b and 802.11g WLAN standards. It will provide information on access points found, the channels they are using and the signal strength. Armed with this information, you may be able to reconfigure your wireless network to reduce interference and improve signal strength.

PSK 4-way Handshake Timeout

6.5 PSK 4-way Handshake Timeout

During WPA or WPA2 security negotiation 4 or 6 EAPOL frames are exchanged during the process which is often referred to as the 4-way handshake and group handshake.

The security negotiation algorithms require the use of cryptographic algorithms and thus require some time to complete. For each EAPOL frame sent to the printer, it may take as long as 850 ms for the printer to respond with an EAPOL frame. Some Access Points (CISCO for instance) are configured with timeouts shorter than this and thus timeout before the 4-way handshake completes. The printer indicates this situation as a failure to connect. The only solution is to re-configure the 4-way handshake timeout in the AP to be greater than 850 ms (suggested timeout value is 1,000 ms or 1 second).

Access Point A device that shares a single Internet connection with multiple computers or other devices. The basic access point controls network traffic.

Ad-hoc network

A type of wireless network in which devices directly communicate with each other rather than through a Wireless Access Point (WAP). Also referred to as peer-to-peer. Ad-hoc networks are typically small and simple, for example, a wireless PC and a wireless printer. Ad-hoc networks are independent basic service stations (IBSS), or direct-connect wireless networks.

Authentication

Authentication is a wireless network security strategy. On a network with authentication, devices use a shared key as a password and communicate only with devices that know the key. Unlike WEP, authentication does not encrypt the data sent between wireless devices. However, authentication can be used in conjunction with WEP. Authentication keys and WEP keys can be identical.

P1035089-003 Wireless Reference Manual 69

AutoIP

A process by which a device on a network automatically assigns an IP address to itself.

BOOTP Bootstrap Protocol (BOOTP) is an Internet protocol that enables a device to discover its own IP address, the IP address of a BOOTP server on the network, and a file to be loaded into memory to boot the machine. This enables the device to boot without requiring a hard or floppy disk drive.

Broadcast packet A packet sent from one device on a network to all devices on the network.

BSS (Basic Service Set)

Basic Service Set describes the type of wireless network that you are using. The BSS type can be one of the following: Infrastructure network or Ad-Hoc network.

Channel A specific radio frequency used by two or more wireless devices to communicate with each other. All devices on the network must use the same channel. The number of channels available varies by country/region.

dBm The power ratio in decibels (dB) of the power referenced to one milliwatt (mW). Examples: 0 dBm = 1 milliwatt, 10 dBm = 10 milliwatt and 20 dBm = 100 milliwatt.

DHCP (Dynamic Host Configuration Protocol)

A protocol used to automatically assign an IP address to each device on a network.

DHCP IP address An IP address automatically assigned by a DHCP server.

DHCP server A computer or access point that gives a unique IP address to each device on the network from a dynamically manages a pool of IP addresses. Unique addresses prevent conflicts. When a user logs in, the server “loans” the user an IP address for the duration of the network connection. When a user logs off, the IP address is returned to the pool for use by device.

Firewall A combination of hardware and software tools that protects a network from unwanted entry.

Gateway A dedicated device (access point or computer) that connects two different networks. For example, a computer on an Ethernet network may act as a gateway between the network and the Internet.

Infrastructure network A type of wireless network in which devices communicate with each other through a Wireless Access Point (WAP), such as a wireless network hub, access point, or gateway.

IP address (Internet Protocol address)

Each computer that connects to a network or the Internet, must have a unique address. IP address numbers are in the form x.x.x.x—for example, 169.254.100.2. Most networks use DHCP or AutoIP to dynamically assign IP addresses. However, a device can be manually assigned a static IP address.

LAN (Local Area Network)

A high-speed type of computer network that connects devices that are a relatively short distance from one another. An Ethernet network is one type of LAN.

MAC (Media Access Control) address

A hardware address that uniquely identifies each device on a network. You can usually find the MAC address printed on the device.

MAC filtering

A method of limiting access to your wireless network by specifying which MAC addresses may communicate on the network. This setting may be specified on wireless access points.

Unicast packet A packet sent from one device on a network to another device on the network.

WEP key A WEP key, or encryption key, is a sequence of alphanumeric characters or hexadecimal digits. After creating a WEP key, you must remember it or store it in a secure location. You may not be able to retrieve the WEP key if you lose it. A WEP key is either 64 or 128 bits long. The first 24 bits of the key are provided automatically. When creating the WEP key, the person creating the key provides the remaining bits (40 bits in the case of a 64-bit key, or 104 bits in the case of a 128-bit key).

WEP Wired Equivalent Privacy (WEP) provides security by encrypting data sent over radio waves from one wireless device to another wireless device. WEP encodes the data sent across the network making the data unintelligible to unauthorized users. Only devices that share the same WEP settings as the printer will be able to communicate with the printer. WEP depends on encryption keys that are static and provides less security than WPA (TKIP).

WiFi (Wireless Fidelity)

A term used generically when referring to any type of 802.11 network, whether 802.11b/g,

802.11a, dual-band, or other. Any products tested and approved as “WiFi Certified” are certified as inter-operable with each other, even if they are from different manufacturers. Typically, however, any WiFi product using the same radio frequency (2.4 GHz for 802.11b or 11g; 5 GHz for 802.11a) will work with any other WiFi product, even if not WiFi Certified.

Wireless Access Point (WAP)

A Wireless Access Point (WAP) is a device through which devices (for example, computers and printers) on an infrastructure wireless network communicate with one another. A WAP is also called a base station.

Wireless network adapter

Each node (computer or device) on the WLAN uses a wireless network adapter into which a wireless transceiver, with a small, integrated antenna, is built. Wireless network adapters might be internal (inserted in a computer or device), external (housed in a separate case), or built-in.

WPA (WiFi Protected Access)

WPA provides security by encrypting data sent over radio waves from one wireless device to another wireless device and by controlling access to network resources through authentication protocols. Only devices that share the same WPA settings as the printer will be able to communicate with the printer. WPA uses encryption keys that change frequently. WPA provides better security than WEP. WPA typically uses TKIP encryption. WPA is not supported on ad hoc wireless networks.

WPA2 A newer version of WPA which typically uses CCMP (AES) encryption. Older access points are less likely to support this. Other possible security settings are WPA and WEP.
