Can a Cisco Aironet 802.11b AP support WPA2 and AES?
Cisco Aironet 802.11b APs do not support WPA2 and AES.
WPA 2 is supported on this equipment:
Aironet 1130AG AP series and 1230AG AP series
Aironet 1100 AP series
Aironet 1200 AP series
Aironet 1300 AP series
Note: Equip these APs with 802.11g radios and use Cisco IOS Software Release 12.3(2)JA or later.
Note: WPA 2 and AES is also supported on Cisco Aironet 1200 series radio modules with the part numbers AIR-RM21A and AIR-RM22A. However, the Cisco Aironet 1200 radio module with the part number AIR-RM20A does not support WPA 2.
Note: Cisco Aironet 350 series products do not support WPA 2 because their radios lack AES support.
