Select the appropriate channel from the list provided to correspond with your network settings. All devices in your wireless network must use the same channel to function correctly. • Wireless Security. To disable wireless security, select the Disable radio button. To enable wireless security, select the Enable radio button. Then to change the security settings to match your network, click the Edit Security Settings button. A new window will appear. Configure the appropriate WEP or WPA settings. WPA Security Mode. If your network uses WPA security, then select WPA Pre-Shared Key. WPA Algorithm. TKIP is automatically selected. WPA Shared Key. Enter the pre-shared key (also called passphrase) for your network. It must have between 8 to 63 characters in length. Figure 6-3: WPA Security Group Key Renewal. You can specify how often you want the dynamic encryption keys to change. Enter the number of seconds in the field provided. Click the Save Settings button to save these changes, or click the Cancel Changes button to undo your changes. If you require more information, click Help. WEP Security Mode. If your network uses WPA security, then select WEP. Default Transmit Key. Select the key you want to use as the Range Expander's default WEP key. WEP Encryption. Select the level of WEP encryption you wish to use, 64-bit 10 hex digits or 128-bit 26 hex digits. Higher encryption levels offer higher levels of security, but due to the complexity of the encryption, they may decrease network performance. Figure 6-4: WEP Security Passphrase. Instead of manually entering WEP keys, you can enter a Passphrase. This Passphrase is used to generate one or more WEP keys. It is case-sensitive and should not have more than 16 alphanumeric characters. (This Passphrase function is compatible with Linksys wireless products only. If you want to communicate with non-Linksys wireless products, enter the WEP key manually on the non-Linksys wireless products.) After you enter the Passphrase, click the Generate button to create WEP keys. Chapter 5: Configuring the Wireless-G Range Expander The Setup Tab encryption: encoding data transmitted in a network passphrase: used much like a password, a passphrase simplifies the WEP encryption process by automatically generating the WEP encryption keys for Linksys products. 19
