For that specific log you sent, code 17 is "Association denied; access
point is resource-constrained".  That basically means the problem is not
your problem, the AP is overloaded and there's not much you can do.  I
guess it would be helpful if wpa_supplicant would simply blacklist that
AP for a while, or if the supplicant could get information out of the
kernel (it can't yet) about the real association failure and then try
another AP.

But the end result is that it's the AP's problem, not a problem with
your machine.

We need to do better with telling you, the user, why something doesn't
work, and that's happening slowly with the new supplicant dbus interface
and the supplicant's nl80211 driver.
