IWMS — The InstantWave Mana gement System

IWMS is a powerful network management system that is fully compatible with the industry-standard Simple Network Management Protocol (SNMP). It features:

• Automatic discovery of all InstantWave devices that are configured within

the same subnet

• Individual and batch-mode remote management of InstantWave devices,

including Multi-Monitor, Batch-Upgrade, Batch-Reset, and Batch-LoadDefault functions. Batch-mode operation is ideal when deploying multiple InstantWave products.

• A friendly end-user interface with a consistent look and feel.

Automatic Disc overy of InstantWave Devices

A powerful auto-discovery algorithm is built into the InstantWave Network Management System. With a simple click on the Auto Discovery icon, all InstantWave devices within the subnet will be discovered. This discovery feature is based on the following techniques:

• DHCP client and IP recovery: The NWH660 has a built-in DHCP client, and

will request an IP address from a DHCP server so that SNMP management can be carried out. Should there be a failure of the DHCP server, the NWH660 will auto-assign itself an IP address (see next) and then automatically negotiate for a new IP address when the server recovers.

• Auto-IP: When the N WH660 cannot get an IP address from the DHC P server ,

it will auto-assign itself an IP address of 169.254.x.x and a subnet mask of

255.255.0.0. A Windows-based system configured as a DHCP client will follow the same algorithm to assign itself an IP addr ess in the same subnet.

When the DHCP server comes back on line, users may need to renew their

10 InstantWave

11-Mbps Wireless Access Poin t

Page 11

stations’ IP settings as described below; otherwise, Windows may continue to use the previous IP address instead of executing the auto-IP procedure.

Windows 95/98

step 1. Click Start/Run, type winipcfg, and click OK. The IP Configuration

dialog box will open.

step 2. Select the network adapter you use to connect to the NWH660. Click

Release.

step 3. Click Renew to retrieve new information (IP address, subnet mask, and

default gateway address) from the DHCP server. Click OK to save the changes and exit the program.

Windows NT 4.0

step 1. Click Start/Programs/Command Prompt . Type ipconfig /release (with a

space after ipconfig) and press Enter.

step 2. Type ipconfig /renew (with a space after ipconfig) and press Enter to

retrieve new information (IP address, subnet mask, and default gateway address) from the DHCP server.

step 3. Type exit and press Enter.

Windows 2000/XP

step 1. Click Start/Programs/Accessories/Command Prompt. Type ipconfig

/release (with a space after ipconfig) and press Enter.

step 2. Type ipconfig /renew (with a space after ipconfig) and press Enter to

retrieve new information (IP address, subnet mask, and default gateway address) from the DHCP server.

step 3. Type exit and press Enter.

Terminology Used in this Guide

BSSID/MAC ID

The BSSID (Basic Service Set ID) is a factory-set ID unique to each InstantWave WLAN product. It is identical to the MAC ID (Media Access Control ID). It allows each InstantWave product to be identified on the wireless network.

ESSID

An Extended Service Set ID (often referred to as Service Set ID, or SSID) identifies the wireless LAN domain that an AP is in. A domain is generally composed of wireless APs you are most likely to communicate with. You can type an existing domain name or create a new one that contains up to 32 characters.

Regulatory Domain

InstantWave products use the license-free ISM (Industrial, Scientific, and Medical) band to communicate through radio waves. Different countries offer different radio frequencies to be used as the ISM band. There are four frequency bands defined by IEEE 802.11: Japan (2.471 to 2.497 GHz), USA, Extended Japan, Canada, and Europe (2.4 to 2.4835 GHz), Spain (2.445 to 2.475 GHz), and France (2.4465 to

2.4835 GHz). To use InstantWave products in a country not listed above, check with your government’s regulating body to find the correct frequency band to use. All InstantWave products are supplied preset to the country of sale’s frequency band.

WEP

WEP stands for Wired Equivalent Privacy. It is an e ncryption scheme that provides secure wireless data communications. WEP uses a 40-bit or 128-bit key to encrypt data. In order to decode the data transmission, all wireless clients on the network must use identical keys.

How to Use this Guide

This user’s guide gives complete instructions for installation and use of the InstantWave NWH660 11-Mbps Wireless Access Point (AP).

Before putting the NWH660 into operation on your LAN, it is important that you adjust the unit’s settings to conform to your networking environment. This can be done with either of two tools included in the NWH660 package: the AP COM-port Configuration utility (AP COMFig) or the Insta nt Wave Managemen t System (IWMS).

AP COMFig lets you carry out basic configurat ion of the NWH660 off-line, through the supplied serial cable, using a networked or stand-alone computer. IWMS is a powerful yet easy-to-use SNMP-based software package for configuration and management of InstantWave devices over netwo rk and internetwork links.

Read throu gh the next section, “Planning the Network,” to lear n how to get the best possible performance from your InstantWave wireless network.

Planning the Network

Infrastructure Network Types

An infrastructure network is formed by several stations and one or more access points (APs), with the stations within a set distance from the AP or APs. Figure 1 depicts a typical infrastructure network topology.

There are three infrastructure network setups that are commonly used. It is a good idea to understand the possible network setups and configuration requirements before planning your wireless net wor k.

Type 1. The simplest wireless infrastructure net work is composed of one

access point (AP) and a few wireless stations communicating via radio waves (Figure 1). This setup enables mobile stations to communicate with each other. The main benefit of this type of network is to extend the range of the network. If an AP is placed between the stations, the radio transmission distance is effectively doubled since wireless computer #1 can talk to wireless computer #2 through the AP. The

Wireless Computer-1

drawback of this configuration is that the effective bandwidth is halved since all communication is relayed by the AP.

Access Point

Wireless Computer-2

Figure 1. Simple Wireless Infrastructure Network

InstantWave

11-Mbps Wireless Access Point

Page 16

Type 2. The next simplest wireless network is very similar to the Type 1

network. This time the AP is connected to a wired Ethernet network as a node. In this configuration the AP operates as a bridge between the wired Ethernet network and th e wireless networks (F igure 2).

Wireless users have the same access to network resources as they would have if they were wired. Such a configuration i s often used to allow roaming, or to extend an existing network into a hard-to-wire environment.

Type 3. The third type of network is composed of multiple APs and multiple

stations (Figure 3).

The reasons for having multiple APs installed are:

1. To increase bandwidth in order to boost overall network performance

2. To extend the coverage range

Any other configuration is usually a mix of these commonly used types.

Planning an Infrastructure Network

This section explains some of the factors you need to consider when planning an infrastructure network. Setting up is a two-step process:

1. Install and configure the InstantWave wireless products.

2. Decide the best physical location of the InstantWave wireless products so as to optimize performance.

The following section gives quick guidelines for these two steps. First, decide whether to have a single AP wireless network or a mul tiple AP network.

Single AP Installation

If you are setting up a sim ple netw ork with only on e AP and a f ew stat ions (a Type 1 or Type 2 network configuration as described in “Infrastructure Network Types,” page 15), all you need to do is make sure the AP and all the wireless stations hold the same domain name (SSID) and security (WEP) settings in their configuration.

Adding a new station to an existi ng infrastructur e network is eas y. Again, all you need to do is to set the newly added station’s domain name (SSID) and security (WEP) settings to be the same as those of the AP.

Multiple AP Installation

Installing multiple APs on the same network (or domain) with overlapping signals (Figure 3, page 15

• Use the same domain name (SSID) and security (WEP) settings.

• Enable the Roaming function on stations that require it.

Note: A station will automatically connect to whichever AP in the same domain is

currently offering the best signal.

18 InstantWave

)

11-Mbps Wireless Access Poin t

Page 19

Roaming

InstantWave products allow wireless stations to roam freely within an infrastructure domain composed of multiple APs with overlapping signal coverage (as in the Type 3 network configuration descr ibed in the previous section). For example, roaming enables Station 1 to move from the AP 1 signal coverage area to the AP 2 signal coverage area without disconnecting from the network. The handover is achieved transparently; the Station 1 user woul d not real ize he had moved f rom AP 1 to AP 2.

The requirements for a roaming environment are:

a) Multiple APs with overlapping signal coverage (see “Multiple AP

b) The APs must be configured to have the same domain name (SSID) and

c) The mobile stations must have the same domain name (SSID) and security

It is advisable that APs on dif ferent TCP/IP subn ets be given diff erent domain names to avoid roaming confusion (see the note below).

Note: For a mobile station t o move between APs without losing i ts netw ork link, the

Installation,” page 18)

security (WEP) settings (see “Encryption,” page 27).

(WEP) settings as the APs.

Roaming function must be e nabl ed on t he st ation, and the APs that t he s tati on roams to must be configured with the same domain name. If a station detects that the signal quality on the link to the current AP is poor, it will search for an AP in the same domain with better signal quality and automatically associate (establish a connection) with it. The station’s IP address, however, will not change. A TCP/IP router will not route packets to a mobile station that has associated with an AP on a different TCP/IP subnet. In other words, if your network consist s of two subnets connect ed by a r outer, a mobile station may roam to a different subnet with the same domain name and then be unable to communicate with other network devices via TCP/IP. To avoid this problem, you must assign dif fer ent domain names to diff er ent TCP/IP subnets .

Hardware Pre-configuration

Before adding the NWH660 to an existing Ethernet network, you may need to set basic parameters — e.g., SSID, security s ettings (WEP), A P n ame, ch ann el number, and IP address — to make the AP compatible with the existing network.

From the AP COMFig utility:

Follow the steps below to connect the AP to a PC for configuration: step 1. Connect the supplied RS-232 cable to the AP’s serial port and connect

the other end to a serial port (COM port) on the PC.

step 2. Power up the AP.

Or from IWMS:

The NWH660’s Ethernet port supports a speed of 10 Mbps. Using regular Category 3 or higher UTP/STP cable, you can connect it directly to a hub or switch.

step 3. Connect the NWH660 and your PCs/network devi ces to the Ethern et hub

or switch.

step 4. Power up the NWH660.

Installing the AP Management T ools

step 1. Insert disk 1 in drive A and click Start/Run. Type a:/menu.exe and click

OK to open the main menu.

step 2. Click Install AP Management Tools to install the AP COMFig Tool,

BSSID Firmware Version

Assigns the AP a unique human-friendly name that allows the AP to be easily identified.

This is commonly called the domain name but is defined in the IEEE 802.11b wireless standard as SSID. Stations and APs in the same group must use the same domain name.

Sets the transmission rate at which data packets are transmitted by the AP. This value determines the basic rates used and reported for this BSS by t he AP. The highest rate specified will be the rate that the AP will use when transmitting broadcast/multicast and management frames. Available options are:

• 1 and 2 Mbps

• All (1, 2, 5.5, and 11 Mbps)

You can change the channel number from here. Refer to the Appendix, page 73, fo r channels supported in each regulatory domain. Click to enable or disable the secure SSID option.

IP:

The InstantWave NWH660 is a DHCP client. It will automat ically try to get IP settings from a DHCP server on the LAN. If it fails to get IP settings from a DHCP server, it will assign itself an IP address in the 169.254.x.x range.

From the IP panel (Figure 12), you can assign an NWH660 a fixed IP address by unchecking the Obtain IP from DHCP box. This lets you view or modify the access point’s TCP/IP address, configure its subnet mask, or add a default gateway (see note below).

Note: An AP will send SNMP response packets ( confirmation packets) dir ectly to an

IWMS PC if the two devices are on the same TCP/IP subnet. If an SNMP response packet from an AP is destined for an IWMS PC on another subnet, the SNMP response packet needs to go through a router or similar gateway. The Default Gateway se tting is t he IP address of such a gateway. If you set the correct defaul t gat ew ay, then you can use an IWMS PC physically located on a different subnet to manage this AP.

InstantWave Product Placement Guidelines

A few tips to mention that are particularly significant in a radio wave communications system:

1. Radio waves reflect or refract from buildings, walls, metal furniture, or other objects. This could result in performance degradation due to the fluctuation of the received signal.

2. Microwave ovens use the 2.45-GHz frequency band. InstantWave also functions in the 2.4 to 2.5- GHz band, and therefore sh ares some of the band w ith microwave ovens. This means that when a nearby microwave oven is in use, it may interfere with InstantWave signals, resulting in performance degradation on the wireless network.

34 InstantWave

11-Mbps Wireless Access Poin t

Page 35

For the best performance, follow the guidelines below in placing the product:

• Place as high as possible, in as open an area as possible

• Avoid placing the AP (especially the antenna) close to metal objects (e.g. file

cabinets, metal cubicles, etc.)

• Keep APs and stations as far away as possible from microwave ovens (10 meters min. is advisable)

When you have decided on a location, follow the steps below to complete the installation.

step 1. Screw the antenna into the back of the AP. Place the AP in the chosen

location.

step 2. Connect one end of an Ethernet network cable to th e UTP port of th e AP,

and the other end to an Ethernet hub or switch.

step 3. Connect the power adapter to the electricity outlet and then to the access

point’s DC-In jack.

step 4. Turn on the AP’s power switch.

Figure 26. IP Configuration

IP Address Setting: The InstantWave NWH660 is a DHCP client. It will automatically ask the DHCP server to assign it an IP address. An administrator can assign a fixed IP to an NWH660 by unchecking the Obtain IP from DHCP box (Figure 26). You may also configure a subnet mask and add a default gateway.

If you assign a fixed IP addres s to an NWH 660, m ake sure t hat all NWH660s w ithin the same net work have the same TCP/IP subnet addre ss.

Note: An NWH660 will directly transfer SNMP response packets (confirmation

packets) to an IWMS PC if it is within the same LAN (the same subnet mask). If an SNMP re sponse packet fr om an NWH660 is des tined for an IWMS PC o n

42 InstantWave

another LAN, the SNMP response packet needs to be forwarded by routers. The default gateway is the closest r outer to the NWH660. If the corr ect def ault gateway is set, you can use an IWMS manager (i.e. a PC running IWMS) physically located in a different subnet to manage this NWH660.

Filter

The next panel in the configuration dialog box is Filter (Figure 27).

Figure 27. Configuration/Filter

This is a one-way protocol filtering mechanism that prevents the NWH660 from transmitting specified protocols packet from a wired Ethernet LAN into the wireless LAN.

Sets the transmission rate at which the data packets are transmitted by the NWH660. In high-interference environments a lower rate can increase overall transmission speed by reducing resends of lost packets This value determines the basic rates used and reported for this BSS by the NWH660. The highest rate specified is the rate that the NWH660 will use when transmitting broadcast/multicast and manageme nt frames. Available options are:

• 1 and 2 Mbps

• All (1, 2, 5.5, and 11 Mbps)

You can change the channel number from here. Refer to the Appendix, page 73, fo r channels supported in each regulatory domain.

If the “auto” option is selected, the access point can choose the best available radio channel automatically.

What are possible sources of interference for the radio frequency link of the AP?

How do I set the AP back to its factory default settings?

What security features does the AP support?

In the U.S., wireless LAN radios transmit and receive on one of 11 channels in the 2.4-GHz frequency band. This is a public band, and does not require a license from the FCC.

Enable the Wired Equivalency Protocol (WEP) to encrypt the payload of packets sent across a radio link.

The AP's Ethernet port (RJ-45 jack) supports 10 Mbps over a 10Base-T connection (half-duplex only).

Interference can come from a number of sources, including 2.4-GHz cordless phones, improperly shielded microwave ovens, and wireless equipment manufactured by other companies. Police radar, electric motors, and moving metal parts of m ach inery can cau s e interference too.

You can load default settings from the menu of the InstantWave Management System (IWMS), a Windows-based SNMP management tool. You may also press the reset button on the back panel of the AP.

SSID: By disabling the “Broadcast SSID” option

Data security: The AP supports 40-bit and 128-bit Wired Equivalent Protocol (WE P).

This section provides you wit h some troubleshoot ing info should you encounter installation or operation problems on InstantWave products. If the problems still cannot be remedied after going through the Troubleshooting section, check the FAQs on page 64 of this manual and at http://www.ndc.com.tw/support/faq.htm

If your problems still cannot be remedied after going through the FAQs and this Troubleshooting section, contact NDC technical support for assistance (see “Technical Support,” page 67).

Symptom Suggested Solutions

The NWH660 is swit ched on, but the Power LED on the NWH660 is off.

The IWMS utility cannot detect an InstantWave NWH660 on the same network.

The NWH660 powers up, but the Ethernet Link LED is off (no connection to an Ethernet network).

The Status LED on the NWH660 front panel is red and flashing.

1. Make sure the power adapter is firmly connected to the power outlet and the NWH660 power connector.

2. The power adapter or NWH660 is defective.

1. Make sure the NWH660 is powered on and connected to an Ethernet work.

2. Check the IP addresses assign ed to the NWH660 and IWMS terminal PC. They should be in the same subnet and unique. For ex ample, if th e NWH660’s IP address is 192.168.1.5 w ith a mask of 255.255.255.0, then the PC’s IP address should be 192.168.1.x with a mask of 255.255.255.0.

Make sure:

1. The Ethernet cable is connected firmly to both the AP and hub or switch.

2. The Ethernet hub or switch is powered on.

Restart (power-cycle) the NWH660 and check the Status LED again. If it is still flashing, you need to return the NWH660 to the reseller for repair.

Transmission performance is slow or erratic.

1. Change the direction of the antenna slightly.

2. There may be interference, possibly caused by a

microwave oven, 2.4-GHz wireles s phone, or m etal objects. Move these interference sources or change the location of the wireless PC or AP.

3. Change the wireless channel on the NWH660.

4. Check that the NWH660 antenna, connectors, and

cabling are firmly connected.
