Mode If you do not have any 802.11a devices in your network, you can dis- able this broadcasting by selecting Disable.

Channel Select the appropriate channel from the list provided to correspond with your network settings, between 36 and 64. All devices in your wireless network must use the same channel in order to function correctly. If you want the Router to automatically scan for a clear channel, then click the checkbox.

SSID The SSID is the network name shared among all points in a wireless network. The SSID must be identical for all points in the wireless network. It is case-sensitive and must not exceed 32 characters (use any of the characters on the keyboard). Make sure this setting is the same for all points in your wire- less network. For added security, you should change the default SSID (linksys) to a unique name.

WEP (Encryption) An acronym for Wired Equivalent Privacy, WEP is an encryption method used to protect your wireless data communications. WEP uses 64-bit, 128-bit, or 152-bit keys to provide access control to your network and encryption security for every data transmission. To decode a data trans- mission, each device in a network must use an identical key. Higher encryption levels offer higher levels of security, but due to the complexity of the encryp- tion, they may decrease network performance. To enable WEP, click the radio button beside Enable. Click the Edit WEP Settings button to configure the WEP keys for your 5GHz, 802.11a wireless network (see Figure 7-9).

Check all the values, and click the Apply button to save your 5GHz, 802.11a settings. To cancel any changes you’ve entered on this page, click the Cancel button. To get more information about the features, click the Help button.

Dual-Band Wireless A+G Broadband Router

5GHz, 802.11a (WEP)

The 5GHz, 802.11a (WEP) screen, shown in Figure 7-9, allows you to config- ure your 5GHz,

802.11a WEP settings. WEP e n c r y p t i o n should always be enabled to increase the security of your wireless net- work.

Default Transmit Key Select which WEP key (1-4) will be used when the Router sends data. Make sure the receiver is using the same key.

WEP Encryption Keys 1-4 offer 64-bit, 128-bit, or 152-bit encryption; select the type of encryption you want from the drop-down box. To disable WEP Encryption, select Disable.

Passphrase (Complete this field when using 64-bit or 128-bit encryption.) 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 be longer than 16 alphanumeric characters. This Passphrase function is compatible with Linksys wireless products only. [If you want to communi- cate with non-Linksys wireless products, enter the WEP key(s) manually on the non-Linksys wireless products.] After you enter the Passphrase, click the Generate button to create WEP keys.

Keys 1-4WEP keys enable you to create an encryption scheme for wireless LAN transmissions. Manually enter a set of values. (Do not leave a key field blank, and do not enter all zeroes. These are not valid key values.) Keys 1-4 offer 64-bit, 128-bit, or 152-bit encryption.

If you are using 64-bit WEP encryption, then the key must be exactly 10 hexa- decimal characters in length. If you are using 128-bit WEP encryption, then the key must be exactly 26 hexadecimal characters in length. If you are using 152- bit WEP encryption, then the key must be exactly 32 hexadecimal characters in length. Valid hexadecimal characters are “0”-“9” and “A”-“F”.
