Follow these steps to set up WEP keys and enable WEP:
Step 1 Follow the link path to the AP Radio Data Encryption page.
Step 2 Before you can enable WEP, you must enter a WEP key in at least one of the
Encryption Key fields.
Note If you enable broadcast key rotation and EAP authentication to provide
client devices with dynamic WEP keys, you can enable WEP without
entering the keys.
For 40-bit encryption, enter 10 hexadecimal digits; for 128-bit encryption, enter
26 hexadecimal digits. Hexadecimal digits include the numbers 0 through 9 and
the letters A through F. Your 40-bit WEP keys can contain any combination of 10
of these characters; your 128-bit WEP keys can contain any combination of 26 of
these characters. The letters are not case-sensitive.
You can enter up to four WEP keys. The characters you type for a key’s contents
appear only when you type them. After you click Apply or OK, you cannot view
the key’s contents.
Note If you enable EAP authentication, you must select key 1 as the transmit
key. The access point uses the WEP key you enter in key slot 1 to encrypt
multicast data signals it sends to EAP-enabled client devices. If you
enable broadcast key rotation, however, you can select key 1 or key 2 as
the transmit key or you can enable WEP without entering any keys.
Step 3 Use the Key Size pull-down menu to select 40-bit or 128-bit encryption for each
key. The not set option clears the key. You can disable WEP altogether by
selecting not set for each key or by selecting No Encryption in Step 5.
Step 4 Select one of the keys as the transmit key. If you select Network-EAP as the
authentication type, select key 1 as the transmit key.
Note Client devices that do not use EAP to authenticate to the access point must
contain the access point’s transmit key in the same key slot in the client
devices’ WEP key lists. However, the key does not have to be selected as
the transmit key in the client devices’ WEP key lists.
