Question: What encryption should be used for 802.11n?
Product and Software: This article applies to all Aruba controllers and ArubaOS 3.2.x and later.
Every 802.11n client has to connect to 802.11n AP with AES encryption if it is using 802.11n rates.
If you set up a TKIP/WEP SSID with HT enabled, no 11n client will connect to it with 11n rates, unless "allow-weak-encryption" is set in the HT SSID profile. If WEP and TKIP are used, the transmission of A-MPDU aggregates will be disabled. This is scheduled to be implemented in a 184.108.40.206FCS.
