Client will not connected to WPA2-PSK network, but will if open

I'm dealing with an Oxinet III device which has a Gigabyte GN-WI01GS wireless card in it. The device will seemingly connect to our WPA2-PSK (AES) secured network, but trying to ping the device is not successful. The device's GUI will show that it is connected to the wireless, then it will change to disconnected. The devices work fine on the old Enterasys wireless we had here. This behavior is exhibited by 3602i connected to a 5508 (7.3.101) and also with an 1131AG connected to a 5508 (6.0.202.0).

I keep seeing "Invalid RSN Descriptor code (254) from mobile 6c:f0:49:a8:6f:2f" in the client debugs. I googled and saw a post that suggested that we may be hitting bug CSCsv21872 (https://www.cisco.com/en/US/docs/wireless/controller/release/notes/crn521780.pdf) but I'm not sure if it has been resolved. I would think that it would be fixed by version 7.3.

Attached are the client debugs from the 6.0.202 controller and the 7.3.101 controller. They look pretty much identical. Below is the WLAN config.

I appreciate any help I can get.

That defect shows as fixed in 6.0.182.0 code, so you shouldn't be seeing it on 6.0.202.0 or 7.3 code

for that device how old are the drivers?

Few things I would just change:

Load Balancing................................... Enabled <---Disable this!!!!

Band Select...................................... Enabled <--- Disable this since you have 802.1b/g only defined in the WLAN

CCX - AironetIe Support.......................... Enabled <---Disable this too for now

Thanks,


Scott

This has been resolved. Turns out the device said it could support WPA2-PSK using AES and TKIP, but it wasn't true in practice. I switched it to WPA-PSK using TKIP and it works fine.
