Chapter 8 Security Setup
Setting Up WEP
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. If MIC is also enabled on the access
point, the key must also be selected as the transmit key in the client
devices’ WEP key lists.
Table 8-1 shows an example WEP key setup that would work for the access point
and an associated device:
Because the access point’s WEP key 1 is selected as the transmit key, WEP key 1
on the other device must contain the same contents. WEP key 4 on the other
device is set, but because it is not selected as the transmit key, WEP key 4 on the
access point does not need to be set at all.
The characters you type for the key contents appear only when you type them.
After you click Apply or OK, you cannot view the key contents. Select Not set
from the Key Size pull-down menu to clear a key.
Step 5 Select Optional or Full Encryption from the pull-down menu labeled Use of
Data Encryption by Stations is.
