The requirement for both the L7920 and L7921B SSIDs mention "fast, secure roaming." When you see that with a 7920, or a 7921 prior to 1.3(4), it will be WPA/TKIP with CCKM. Keep the whole requirement in mind, not just the "most secure form of encryption."

It will fail when it roams. But WPA2 CCKM with 7921 on a single AP it will work. That might confuse things. If I would have an question saying use the most secure. I would check the firmware, and if older than 1.3(4) then I would go to my proctor and explain to him that WPA2 isn´t supported for roaming and ask if he minds... regards.

On the solutions guide this says you must run wpa/tkip to support CCKM, but I seem to be running 1.2(1) software on my 7921 an am able to connect to my SSID that is running WPA2/AES CCKM. I thought if you have cckm enabled on the wlan that the clients connecting must support cckm. Has anybody else seen this? Am I missing something?
