If sounds like the AP may have had an issue if the country IE is no longer present and by the quick looks of your output it could have been.. so unless you're confident of the AP I would think this is an AP bug. If its a STA bug for sure though we certainly need to address the issue on 2.6.35 even if 2.6.36 has a proper fix of ignoring the IE altogether. > P.S.  My thread about the AP that works on 2.6.34 but can't associate > most of the time on 2.6.35-rc6 is the same AP but with the new > firmware.
