Atheros Wifi card, CCX not supported for WLC 6.0

Laptop Fujitsu with Wifi adapter : Atheros AR9285 , lastest driver v10.0.0.52 April 2012

Win 7 32bit pro

WLC 6.0.196.0 and AP 1142 , associated in 802.11G or N

WPA 2 preshared key.

WLC Roaming parameter : minimum RRSI  -80dbm, roaming hysteresis 2dB, adaptive scan threshold -70dBm, transition time 5sec.

The laptops are supposed to be compatible with CCXv5 program, but in WLC (and two controllers CT-5508) the client is not seen as CCX client compatible !

So roaming is bad. Even with a very good and dense wifi coverage (no coverage hole detected), because the laptop still stay associated with a far AP (until -90dbm), instead of roaming with the nearests APs (-40dbm !!)

Does someone has any idea , or experience with CCX compatibility ?

Many thanks

I suggest you move this to the wireless community.

Atheros are supposed to be compatible with CCX. If they appear as not compatible on the WLC then contact the vendor. Make sure if the CCX option can be enabed/disabled from the client. Make sure that the Aironet IE is enabled on the WLAN to which the client is connected.

For the roaming thing it is fully client dependent. You need to refer to the vendor to investigate why the client does not roam when the old signal become too weak and how to improve this.

Upgrading to a later WLC version will also be better. Better support with CCX etc.

You need to tweak your wlc configuration. If your environment is high density, disable the lower data rates. Disable everything below 11mbps on the 2.4 and everything below 12mbps on the 5.

If you don't know what is best practice, then download the wlc config analyzer and load one of your show run-configs and it will tell you what you needs to adjust. This should help a lot.

Then worry about ccx on your client.
