Do you have other APs around? I'm wondering if the driver select other
strong signal APs.

Another try is to set a different sensitivity with (iwconfig sens xx).
The current roaming threshold is 8 (means start roaming if we detected 8
lost beacons) and disassociate threshold is 3 times of the roaming
threshold. Try to see if a bigger value makes it better for your case.
