That's really odd; that patch (the don't-send-empty-extended-rates-IE
patch) shouldn't have anything to do with this behavior, if it did you
wouldn't get associated to the AP in the first place I think.  You're
100% sure that this patch is causing the problem?  Can you post the
output of running wpa_supplicant with the "-dddt" flags and also post
the 'iwlist scan' output for your AP?
