Part 1: Product description The IBM High Rate Wireless LAN Gateway provides small offices and home offices (SOHO) an economical way to connect a small local area network (LAN) to the Internet using an external DSL/Cable modem. With its built-in wireless access point, you can connect your IEEE 802.11b-compliant mobile computers or other clients to establish a home network. The IBM High Rate Wireless LAN Gateway has the following features.
v DMZ: The IBM High Rate Wireless LAN Gateway can support some special applications and Internet games. With DMZ, one designated computer is removed from behind the built-in firewall and exposed to the Internet. This speeds up Internet gaming and might be required from special applications. v Access control (Packet filtering): The IBM High Rate Wireless LAN Gateway can monitor and block specific packets or applications.
v One IBM High Rate Wireless LAN Gateway unit v One AC power supply v One power cord Note: In the event that your Gateway comes with two power cords, be sure to use the one labeled for your country. One is labeled for use in the United States and Canada, and one is labeled for use in Japan.

Part 2: Configuration The IBM High Rate Wireless LAN Gateway has a Web-based setup utility. Note: It is not recommended that multiple users be logged into the Web-based setup utility at the same time. Web-based interface The Web-based setup utility has an easy-to-use graphical user interface (GUI). Note: Updated Web browser software can be downloaded from: v Netscape: v Microsoft: The Gateway is pre-configured with the default IP address of 192.168.1.1.
Note: All IBM High Rate Wireless LAN Gateways are factory-configured with ″default″ as the default Administrator name with no password needed. After login, the Language selection window opens. 5.

Part 3: Setting up the wireless access point in the IBM High Rate Wireless LAN Gateway The IBM High Rate Wireless LAN Gateway is a multifunctional device with an integrated IEEE 802.11b-compliant WiFi certified access point. You can use it as a base station for your wireless network. Through the following procedure, you can turn on the wireless function of the Gateway and connect your wireless devices with other Ethernet nodes such as a DSL/Cable modem, printer, file server, or other wireless clients.
Channels are the spectrum range where your wireless signals are transmitted. The clearer the channel, the better your network performance. You can select the desired channel from the pull-down menu. Wired equivalency privacy (WEP) encrypts the packets sent by the wireless Gateway. The security settings can affect performance, and must be balanced to your needs. Note: A higher encryption setting is more secure but will not perform as well as a less secure setting.
Wireless Settings - Advanced Request to send (RTS) Threshold: In some situations, not all clients in a WLAN are aware of each other (hidden node problem). That can lead to different WLAN clients transmitting to the Gateway at the same time, therefore jamming both transmissions. RTS Threshold is a packet size above which the Gateway will expect to use the RTS mechanism. This is negotiated with the client.
Wireless Settings - MAC Control Setup After you enable the MAC access limit function, then you can determine the access mode. In IEEE 802.11b-compliant devices, the MAC address is a means of controlling network access. MAC addresses can be found in the package of the network interface card (NIC). The following is an example of a MAC address: v 00:30:AB:00:00:01 After you have entered the MAC address, click Apply to save your settings.
Block or Allow: You can list specific MAC addresses to block or allow in this window. Blocking a specific MAC address will allow everyone else with the correct settings to access the LAN and the Gateway. Allowing a specific MAC address will allow only that MAC address access to the LAN and Gateway as long as WEP and ESSID are correct. Wireless Settings - Status Monitor The Status monitor is an advanced function for experts only.
