I don't see anything obviously wrong with your configuration. And yes, WPA is expected to work regardless of the underlying channel. > wlan0: CTRL-EVENT-DISCONNECTED bssid=00:0b:6b:23:35:a5 reason=15 Reason 15 means the WPA 4-way handshake timed out from the AP's point of view. This indicates the AP is unable to receive any (or some) frames sent by the client during the WPA authentication phase. Can you run 'ifconfig ath0 debug' on the AP and show additional lines printed to dmesg while a client tries to connect? Can you show the output of 'netstat -W ath0' and 'netstat -I ath0' twice? Once from before the client tries to connect, and once after. Are you sure that communication on 5 GHz works well in general? Does an unecrypted network on 5GHz perform worse than a 2GHz one? What is the packet loss rate for a ping to the AP's IP address on unencrypted 5GHz?
