WEPencryptionshould alwaysbe enabled toincrease thesecurity of yourwireless net-work.Default Transmit Key Select which WEP key (1-4) will be used when theRouter 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; selectthe type of encryption you want from the drop-down box. To disable WEPEncryption, 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. ThisPassphrase is used to generate one or more WEP keys. It is case-sensitive andshould not be longer than 16 alphanumeric characters. This Passphrase functionis compatible with Linksys wireless products only. [If you want to communi-cate with non-Linksys wireless products, enter the WEP key(s) manually on thenon-Linksys wireless products.] After you enter the Passphrase, click theGenerate button to create WEP keys. Keys 1-4 WEP keys enable you to create an encryption scheme for wirelessLAN transmissions. Manually enter a set of values. (Do not leave a key fieldblank, and do not enter all zeroes. These are not valid key values.) Keys 1-4offer 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 thekey 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 inlength. Valid hexadecimal characters are “0”-“9” and “A”-“F”.41Figure 7-9Instant Wireless®Series5GHz, 802.11aThe 5GHz, 802.11a portion of the Setup screen, shown in Figure 7-8, allowsyou to configure your 5GHz, 802.11a wireless network settings.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 correspondwith your network settings, between 36 and 64.

The SSID must be identical for all points in the wireless network. Itis case-sensitive and must not exceed 32 characters (use any of the characterson 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 anencryption method used to protect your wireless data communications. WEPuses 64-bit, 128-bit, or 152-bit keys to provide access control to your networkand encryption security for every data transmission. To decode a data trans-mission, each device in a network must use an identical key. Higher encryptionlevels offer higher levels of security, but due to the complexity of the encryp-tion, they may decrease network performance. To enable WEP, click the radiobutton beside Enable. Click the Edit WEP Settings button to configure theWEP 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, 802.11asettings.
