I just discovered that  "iwconfig wlan0 ap auto channel auto" is the
one causing the problem on 2.6.29-rc8. Remove the line and it'll
associate to the AP. Just tried on two different APs a few times, and
it seems to behave that way. If I execute the "auto" command, it'll
fail to associate, but works fine with the patch.

Jeff.
