Chapter 3 - Software Configuration

Channel

The 802.11g and 802.11b specifications supports up to 14 overlapping channels for radio communication. To minimize interference, configure each 802.11g AP to be non-overlapping; select Auto from the Channel drop-down list to enable the system to select a clear channel during boot up as your operating channel.

Ensure that any R100 Wireless Gateways sharing the same channel (or channels which are close in number) are as far away from each other as possible, based on the results of your site survey of the facility. There is a site survey utility on the R100 Driver CD.

Wireless Mode

This field allows you to specify the transmission rate. Selecting Auto (recommended) allows 802.11g and 802.11b clients to connect to the R100 Wireless Gateway. Selecting 54G Only maximizes performance, but prevents 802.11b clients from connecting to the gateway. If 54g Protection is checked, G-Mode protection of 11g traffic is enabled automatically in the presence of 11b traffic. Select 802.11b only when backward compatibility is needed for some older wireless LAN cards with a maximum bit rate of 2Mbps.

Authentication Method

This field enables you to set different authentication methods which determine different encryption schemes. The relationship between Authentication Method, Encryption, Passphrase and WEP Keys is listed in the following table. If you are not using a RADIUS server in a home environment and all your clients support WPA, using WPA- PSK is recommended for better security. If WPA or Radius with 802.1x, is selected, additional settings for the RADIUS server in the Wireless

–Radius field are required.

Encryption (WEP)

Traditional WEP encryption is applied when Open or Shared Key, Shared Key or Radius with 802.1x authentication methods are selected.

When WPA-PSKor WPA authentication methods are used, the newly
