WEP Encryption Setup

The Wi-Net Window now supports interactive operation with wireless networks that have 64-bit or 128bit Wired Equivalent Privacy (WEP) encryption. This is the originally

specied form of wireless encryption and consequently is supported by most

existing hardware.

On the Wi-Net Window you dene one WEP key to use when communicating

with encrypted wireless networks. This key is applied to all networks that are detected as being encrypted. To enter the WEP key you need to

specify the key size (64 or 128 bit), the authentication type (Open System or Shared Key), the active key position (1-4) and the hex digits that comprise

the key value. When in doubt as to

the authentication type, choose Open System to start.

From the Encryption submenu,

press SEL to view and edit the WEP Encryption setup. Use the down arrow to scroll through

the Encryption submenus. Press SEL

to view or edit the corresponding WEP Encryption choices.

Hex digit entry is similar to entering an IP address on the Wi-Net Window. Use the right/left arrow keys to position the

cursor beneath the digit you wish to change. Press the up or down arrow

key to increment or decrement the value of the corresponding digit. Digit entry supports rollover so you can increment from an ‘F’ to a ‘0’ and vice versa.

Your WEP settings are retained while

the Wi-Net Window is off and even

during a battery change.

When entering a 128-bit WEP value

there are 3 “pages” for entering the 26 hex digits. Scrolling right or left off of

one page connects to the next. The

current page number (1-3) is displayed as a xed number above the WEP

value.

Once the WEP value is entered, press

SEL to always save changes and return

to the next Encryption submenu. Press the SETUP, SCAN or PING key to exit

WEP editing and start the selected

operation. When exiting in this manner, if the WEP key value has changed, you

are presented with the option to save

the changes (SEL), discard the changes (Down Arrow) or cancel and return to

WEP editing (Up Arrow).

You need to know your encryption

parameters whenever you setup a

wireless client or connect with the Wi-Net Window. For convenience

you should make a note of them so you don’t need to read them from the AP each time. It is also good to write down the Access Point’s IP address so you can quickly connect with it for review or to make changes. Many Access Point manuals have a place for jotting this information down. Of

course since these are your network’s

security settings, they should be kept in

a protected location.

For more detailed information about how access points are congured for WEP,

see the Wi-Net Window Application Notes posted on our web site:

Important Note Regarding Battery Installation

Variable Scan Rate and Hidden SSID Connectivity

If your unit does not power on, please check the batteries to make sure they are rmly seated in the battery cage and

all contacts are touching.

Occassionally, the initial stiffness in the

battery cage will prevent the battery

terminals from making good contact with the positive battery terminal.

The Wi-Net Window now supports

three new advanced features based on customer feedback. These features

include alternate signal strength

measurement units, a variable scan rate and support for connectivity to access points with hidden SSIDs. All of these

are controlled via a new Expert Setup

sub-menu. The following sections

describe these additions in detail.

Signal Strength

The Wi-Net Window displays signal strength as a percentage value. This value represents an overall signal

quality based on several measured parameters. This format was selected because it is widely understood by most

people.

For more technical users a signal

SETUP

4 5 6 7 8 S

CAL

strength measurement in dBm is sometimes preferred. dBm is an abbreviation for the power ratio in decibel (dB) of the measured power referenced to one milliwatt (mW). It is used in radio, microwave and ber optic networks as a convenient measure of absolute power because of its capability

to express both very large and very

small values in a short form. Zero dBm equals one milliwatt. A 3 dB increase represents roughly doubling the power, which means that 3 dBm equals roughly 2 mW. For a 3 dB decrease, the power is reduced by about one half, making −3 dBm equal to about 0.5 milliwatt.

For these more technical users, an option to display signal strength in dBm

has been added to the Wi-Net Window. This is accessed via the Expert Setup

sub-menu (see menu navigation chart in

a later section).

Press the SEL key to cycle between

dBm and percentage (%). When dBm is

selected the CAL icon is shown on the

scan display. The 10 LEDs on the Wi-Net

always indicate the percentage signal strength.

For wireless networks the signal strength

ranges from around –20 dBm to –90 dBm. When the AP is out-of-range the signal strength is displayed as –99 dBm.

Scan Rate

The Wi-Net Window actively scans

for existing wireless networks. Active scanning is much quicker and more responsive than passive scanning. By default the Wi-Net scans the current

(i.e. displayed) network once every two

seconds and scans for all networks once every six seconds. If a hidden SSID is specied (see section below), it is scanned every four seconds. Since active scanning requires more power,

these rates were chosen as a reasonable

balance between functionality and battery life.

For some users the two second

SETUP

scan rate is not fast enough for their application. Consequently an optional set of scan rates has been added to the

Wi-Net Window. These are accessed

via the Expert Setup sub-menu (see menu navigation chart in a later section).

Note that the faster scan rates can

potentially decrease battery life.

Press the SEL key to cycle through the

list of rates (in seconds): 0.5, 1.0, 1.5,

2.0, 2.5, 3.0

Service Set Identier (SSID)

A Service Set Identier (SSID) is a 32-character name that, along with a channel number, identies a wireless Access Point (AP). The SSID is used to identify the various wireless networks

available and allows selecting the one to connect to. Thus when you turn on your laptop you can choose to connect to a wireless network

named “Joe’s Coffeehouse” or “Bob’s Insurance”. The default SSID for an

AP is typically set to the manufacturer’s name such as “Linksys” or “Belkin”. It

is always a good idea to change the

SSID from the default to a unique one for your situation. Otherwise you risk interference with other APs using the same default SSID. Also it makes it much easier for you to locate and

connect to your own wireless network.

Hidden SSID

Most Access Points have an option to not broadcast, or hide, their SSID (see gure below). By not publicly revealing its name, the wireless network becomes “invisible” to casual users. In order to

connect to a hidden AP you need to

already know its SSID.

The most common reason for hiding an

SSID is to increase network security. There is an ongoing debate amongst security experts as to the viability of SSID hiding for security. Naturally both sides feel strongly that their position is the correct one. It must be acknowledged

that there are several readily available

software packages that can uncover the SSID of a hidden network.

Ever since the release of version 1.05,

the Wi-Net Window has been able to

detect networks with hidden SSIDs. Because the SSID is not known, these

networks are represented by a sequence

of 10 asterisks, similar to a hidden password on a computer.

Since these networks are typically

revealed via passive scanning, the signal

strength update rate can be erratic.

Additionally, the Wi-Net Window is

unable to connect to a hidden network

because its SSID is unknown. Without a connection, the Wi-Net cannot negotiate for an IP address or interact with other systems on the network.

With this latest rmware release (v1.20), the Wi-Net Window is now able to connect to a specied hidden

network. This is achieved by entering

a target SSID into the Wi-Net’s setup parameters. When a target SSID is specied, the Wi-Net initiates scans for that network by name. If the hidden network is located, it is displayed with its SSID enclosed in parenthesis.

Note that the parentheses are only shown if a general scan reveals the same AP (based on MAC addresses) broadcasting without an SSID.

Entering an SSID

SETUP

The SSID for a hidden network is accessed from the Expert Setup submenu via the main Setup Menu (see menu navigation chart in the following

section).

An underline cursor is initially placed

at the end of the SSID. Scrolling right and left ( ) moves the cursor under

the character to change. Scrolling up and down () rotates through all the

characters for that position. Character

entry supports rollover so you can

seamlessly move in either direction

through the character list. The character

list is composed of the alphabet, with interleaved upper and lower case letters, followed by symbols and numbers:

Press the SEL key to activate an editing

screen that contains the current SSID, if any, and displays the ID icon.

!”#$%&’()*+,-./:=;<>

?@[]\^_{}|~0123456789

Starting with a blank (space) character,

scroll up () to increment through the alphabet with each letter appearing as

an upper/lower case pair. Otherwise, scroll down () to decrement through the digits (9-0) followed by the set of symbols.

Hold down an arrow key to initiate

automatic scrolling in the corresponding direction. The right and left arrow keys wait a second before starting.

There are several 2-key combinations that allow for more efcient movement and editing. To delete to the left, hold

down the right arrow key and press

the left arrow. Continue to hold the left arrow and it becomes an auto-delete to the left (after a one second delay). To move to the end of the SSID, hold down the left arrow key and press the right

arrow. When auto scrolling with the up

arrow key, press the down arrow to leap upward by 10 characters. When auto scrolling with the down arrow key, press the up arrow to leap downward by 10 characters. For these last two, if you

hold the second key the auto scrolling is

temporarily suspended so you can see

where you are in the character list.

Once an SSID is entered, press SEL to

always save changes and return to the

next Expert sub-menu item. Press the SETUP, SCAN or PING key to exit SSID

editing and start the selected operation.

When exiting in this manner, if the SSID has changed, you are presented with the option to save the changes (SEL), discard the changes (Down Arrow) or cancel and return to SSID editing (Up

Arrow).

The SSID name is retained while the Wi-Net Window is off and even during a

battery change.

During scanning a ping is sent to the Internet IP every 15 seconds. If a response is received, an Internet indicator (i) is displayed.

If an Access Point (AP) is detected that encrypts its data, the letter “E” displays on the LCD during scanning. If the data is encrypted, Ping testing is not operational.

If two WLANs are using the same SSID and channel, a twin status (t or twin) is displayed (they are differentiated by their MAC addresses). This can indicate

a problematic network conguration or

an attempt to initiate an “evil twin” scam.

Additional network status is available when operating in the Advanced Mode. See Advanced Mode Option in the Main Setup Menus section of this manual for a complete list of status indicators.

Multiple presses of the SEL button display the unique IP address assigned to your Wi-Net Window, the Router’s IP address, and the Access Point MAC address.

SELSEL

Each of these displays are shown for up to 10 seconds. Press SEL to move past them more quickly.

When operating with DHCP off, editing is allowed on the My IP and Rtr IP displays. Once editing starts, the display remains active until accepted via the SEL key, or canceled via the SCAN, PING or SETUP keys.

If the router and access point are the same, it is indicated by the caption “AP & Router IP.”

Press SEL to display the corresponding MAC address. Since most wireless networking hardware has a visible MAC address label, this allows the components of the wireless network to

be identied more easily.

A scan for all hosts (AP’s) is initiated every 6 seconds. If a WLAN is not detected after 4 scans (24 seconds), its signal strength is set to 0%. If there is no activity after an additional 70 seconds, the WLAN is removed from the scan. It may be removed earlier if a more active WLAN displaces it.

The currently displayed WLAN is locked and will not be removed unless you scroll to a different WLAN or the unit is turned off. The Wi-Net Window

tracks and identies up to 8 WLANs

simultaneously based on signal strength.

Ping Testing Mode

The Ping test is used to verify connectivity to resources on or off the network and IP addresses. The Ping test can be run in DHCP or manual addressing mode.

During Ping testing, the channel number, SSID, ping target and count values for the transmitted and received ping packets display on the LCD. The WLAN signal strength displays on the LCD in percentage format and also on the light bar at the top of the unit.

Use the left and right arrow keys to view the ping test results for the IP addresses associated with the WLAN selected, including the Router, DNS, target IP addresses 1-4, and the Internet.

As you scroll through the respective targets during ping testing, press SEL to identify the Wi-Net Window’s IP address, the IP address of the wireless network device pinged, the length of time it took for the last ping, as well as the average ping response time in milliseconds.

SELSEL

The Ping Target IPs can be viewed and edited from this display. The Internet IP can only be edited from the Target Setup submenu during Setup mode.

Pinging Unsuccessful

TEST

When a ping target is selected, the Wi-Net Window tests the currently

dened network parameters and

displays one of the following messages if it is unable to to send a ping.

The problems that can prevent a ping from being successful include a non-

existent target (i.e. no ARP response),

an invalid Router IP (when the target is not on the local network), or when the unit’s IP address (My IP) is already in use on the network.

When starting Ping testing, the following messages may be displayed if a problem or delay is encountered

When entering PING this message is displayed if no WiFi networks have been detected. Goes to SCAN after a 5 second

delay. Press any key, except

SETUP, to immediately go to SCAN.

DHCP Off Err IP = 0.0.0.0

When entering PING this message is displayed if DHCP is not active (off) and a Manual IP has not been entered (defaults to 0.0.0.0). Goes to SETUP after a 5 second delay.

Press any key, except SCAN, to

immediately go to SETUP.

Ad-hoc network no DHCP offered

When entering PING this message is displayed if the current WiFi network is ad-hoc (IBSS) and DHCP is on. Ad-hoc networks do not support DHCP so the Wi-Net Window cannot be automatically assigned an IP address. Turn off DHCP and

enter a Manual IP in order to ping ad-hoc networks. Goes to SCAN after a 5 second delay.

Press any key, except SETUP,

to immediately go to SCAN.

Waiting on DHCP for my IP x

When DHCP is on, this message is displayed whenever the Wi-Net Window’s IP address is required before proceeding (e.g. when entering PING). The number is incremented for every DHCP request sent (about once every 10 seconds) until an IP is assigned or 12 requests have been sent. After 12 unanswered requests the display goes to: No

DHCP located to assign my IP.

No DHCP located to assign My IP

This indicates that the current network has not responded to 12 DHCP requests. This could be due to the lack of a DHCP server, or because the WiFi signal is encrypted. Pressing PING or SCAN causes the DHCP request cycle to restart.

Waiting for DHCP

to nd Routr IP

This indicates that the WiNet Window is issuing DHCP requests on the current network and must complete this step before the IP address of the router is known.

No DHCP located

to nd Routr IP

This indicates that the current network has not responded to DHCP requests; consequently the Wi-Net Window is unable to determine the IP address of the router.

DHCP On (Off) Verifying Addr

When entering PING this message is displayed while the

Wi-Net Window veries that its

IP is valid for use on the current network (i.e. no other system responds to an ARP of that IP).

My IP is in use on this network

This indicates that the IP assigned to the Wi-Net Window

conicts with another system

on the network. This most

often occurs when assigning a Manual IP, so return to SETUP and enter a different Manual IP. Otherwise it could result from a faulty DHCP host or indicate that a new system was just added to the network.

My IP is invalid

When entering PING this message is displayed if the Wi-Net Window is unable to establish a proper IP for use on the current network.

No DHCP host was found

This message is displayed when selecting the Last DHCP option from the SETUP menu and the current network is ad-hoc or has not responded to any DHCP requests. The display returns to the SETUP menu after 5 seconds.

No DHCP info is available

This message is displayed when selecting the Last DHCP option from the SETUP menu and DHCP is off, or DHCP requests are still being sent to the current

network. The display returns to the SETUP menu after 5 seconds.

Wireless card not detected

This message is displayed when the Wi-Net Window starts and it is unable to communicate with its wireless hardware. The display goes to the SETUP menu after 5 seconds.

DNS is unknown when DHCP is off

This message is displayed during PING if information on the DNS target is requested by pressing the SEL key. It indicates that a DNS IP is only available when communicating with a DHCP host.

Manual IP cannot be 0.0.0.0

This message is displayed after editing the Wi-Net Window’s Manual IP and pressing SEL. An IP address of 0.0.0.0 is not permitted on a network. After 6 seconds the editing display reappears with the original IP value (prior to editing).

Manual IP cannot be 224-255.x.x.x

This message is displayed after editing the Wi-Net Window’s Manual IP and pressing SEL. The IP address range of 224.

x.x.x to 255.x.x.x is reserved for

special use on a network. After 6 seconds the editing display reappears with the original IP value (prior to editing).

Rtr must be on

MyIP LAN segment

This message is displayed when editing the Router IP and trying to change its upper address to be different from the Manual IP address. The Router IP must match the Manual IP wherever the Netmask bits are set. This is necessary in order for them to be operating in the same network address space.

Rtr: No ARP resp

This message accompanies the display of a router’s IP address. It indicates that ARP requests to the router for its MAC address have not been returned.

An access point is a device that connects wireless devices together to create a wireless network. An AP usually connects to a wired network, and can relay data between wireless and wired devices. APs operate on a selected channel (1 to 11) and broadcast their name (SSID) to allow connection by wireless devices.

Ad-hoc wireless network

A wireless network between two wireless capable devices (normally PCs), where no wireless access point is involved.

ARP = Address Resolution Protocol

Used to determine Ethernet (MAC) address when a device starts to communicate with another. The host wishing to obtain a physical address broadcasts an ARP request and the device responds with its MAC address so further communication can be

specically addressed between the two.

DHCP = Dynamic Host Conguration

Protocol -

Communications protocol where a range of IP addresses are managed centrally and assigned automatically to network devices on demand. A DHCP server is not required on a WLAN, but if it does

not exist, all the devices on the WLAN must be manually congured. The Wi-

Net Window reports the following from the DHCP server:

- an IP address for itself (My IP)

- the IP address of the DHCP server

- the Netmask in use

- the Router’s IP address

- the IP address of the DNS server

DNS = Domain Name Server Provides translation of URL addresses (like www.yahoo.com) to IP addresses DNS servers are found on the Internet, and thus are of interest to the Wi-Net Window because accessing (pinging) the DNS server proves that the Wi-Net Window can access a device on the WLAN.

Gateway = Router - see below

IP = Internet Protocol

Actually TCP/IP = Transmission Control Protocol/Internet Protocol, but commonly abbreviated to IP.

Communications addressing scheme

dened by DARPA (Defense Advanced

Research Projects Agency) to control the publicly accessed Internet network.

IP Address

Specic number assigned to a single

device to allow it to be uniquely

identied on the network to which it is

connected. On a WLAN, the IP address must be within the range of addresses

dened for that WLAN by the Network

Mask in use. On the Internet, all IP addresses must be universally unique

to allow addressing that specic device. IP addresses consist of 4 hexadecimal

digits that are commonly written in “dotted decimal” format. 192.168.254.4

is an example. Note that each set of

decimal numbers divided by the periods must be in the range of 0-255 as they

represent hexadecimal values of 00-FF.

ISP = Internet Service Provider

Commercial supplier of access mechanisms for public access to the Internet.

MAC Address = Media Access Control Address

Hardware serial number that uniquely

identies a device on a WLAN.

Netmask = Network Mask = Subnet Mask

Network Mask = Subnet Mask

IP addressing scheme that divides the entire IP address network into smaller sections (Subnets.) The Network mask is used to identify an IP address as being located either on the WLAN or on the Internet.

PING = Packet Internet Groper

A simple communication protocol (ICMP Echo) used to request an echo back from an addressed device (target). The Wi-Net Window uses this to verify IP connectivity between itself and another device.

Router = Gateway

Routers are located at gateways, the places where two or more networks connect. A wireless router forwards data packets across the WLAN, typically to the Internet. A router has an IP address and MAC address of its own for direct communications, which differentiates it from a HUB or SWITCH. A hardware

box sold as a router will usually include

a HUB or SWITCH chip inside, providing a convenient connection point for multiple Ethernet devices.

SSID - Service Set Identier

A unique network name that identies a

wireless network.

Target

In the Ping protocol, an IP address must be selected to receive an echo request. This address is the “target” address for that Ping. A target IP address may be selected manually in Setup. This target can be on the WLAN, or anywhere else accessible through a router connected to the WLAN. If the target is not on the LAN, the router IP address must be known so the Ping can be sent to the router which forwards it on toward the ultimate location.

WLAN = Wireless Local Area Network

A Wireless LAN is a computer network that connects workstations and personal computers for the purposing of communicating with each other and to share data and devices, such as

laser printers, faxes, and data storage

devices.
