If you have a means for capturing wireless sniffer traces of the frames
exchanged between the AP and these various station devices, it would be
useful to take a look at what the exact differences in the Association
Request frame contents. For the nl80211 interface case itself, it would
be interesting to see what is the exact information element that makes
the AP misbehave, e.g., by removing them one by one (this might be
either in wpa_supplicant or kernel) until the association succeeds.
