Note When you enable TKIP, all WEP-enabled client devices associated to the access
point must support WEP key hashing. WEP-enabled devices that do not support
key hashing cannot communicate with the access point.
Note To use TKIP, the Use Aironet Extensions setting on the AP Radio Advanced page
must be set to yes (the default setting).
Tip When you enable TKIP, you do not need to enable broadcast key rotation. Key
hashing prevents intruders from calculating the static broadcast key, so you do not
need to rotate the broadcast key.
Follow these steps to enable TKIP:
Step 1 Follow the steps in the “Setting Up WEP” section on page 4-9 to set up and enable
WEP. Select either optional or full encryption for the WEP level.
Step 2 Follow this link path to browse to the AP Radio Advanced page:
a. On the Summary Status page, click Setup.
b. On the Setup page, click Advanced in the AP Radio row under Network
Ports.
Step 3 Select Cisco from the Temporal Key Integrity Protocol pull-down menu.
Step 4 Make sure yes is selected for the Use Aironet Extensions setting. Key hashing
does not work if Use Aironet Extensions is set to no.
Step 5 Click OK. TKIP is enabled.
