Description (partial)


The Cisco AP does not transition properly from PSK to No Security mode.  When this transition occurs, 11n stations are not recognized as all MCS rates are absent (sh dot11 ass all).  From a protocol perspective, the .11 frames are correct however the AP code does not appear to be working as expected.

11n clients no longer 11n capable.  Will not support 11n Tx.


AP SSID set to use WPA2/AES/PSK.

Change SSID to use WPA2/Open
