We have WISM controller running version 4.2.130. We are attempting to use an SSID with either A or G radio. This is not working for A radio but works for G. Looking at debug, i see that there is no dhcp info on the failed A radio connection. The client gets limited connectivity messege with that 169.x.x.x address indicating no dhcp. Once doing more testing, I figured that A radio works with WPA2 with TKIP. It does not work with WPA2 with AES. Is there a known issue or bug with AES, 802.11a, and DHCP?
Any help is appreciated.
