I'm opening this new bug on behalf of an Ubuntu user, bjaglin. Will attach
their relevant debug files and comments they had posted to a bug in Launchpad:

I can't connect at all to my home WPA-Personal AP. I could not get any better results by getting closer to the signal. AFAIK, I was using madwifi under Jaunty on the same hardware, and despite a slow rate that I thought was due to the old 802.11b adapter, it was reliable. I have a rt2870sta USB dongle which had a similar symptom (association to the AP failing); installing linux-backports-modules fixed the problem for it, but not for the built-in adapter.

The same hardware at the exact same distance from the AP works just fine in Win7. If I had no USB dongle, this would be a showstopper for me."

(Ignoring rt2870sta...)

Looks like he associates most of the time, but has trouble getting an IP address via DHCP.  Then the connection drops pretty quickly -- some sort of calibration issue?

I dunno, it goes from connected to 'deauth by local choice' (i.e. NM drops the connection, not mac80211) in just over a couple of seconds.  I've had this kind of thing happen with NM before where using the wpa_s directly would work fine.  Ath5k has a pretty long scan time, I think it might hit some timeouts in NM or something like that.  Or maybe, as you say, dhcp doesn't work so NM bails on the connection.

Comment 6 bjaglin 2009-11-09 18:31:21 UTC

I compiled the latest madwifi from SVN (4100) and tried it on the same hardware, and it did work, even if the speed was not there... However, looking at the logs, it looks like the driver throw a lot of warnings. I am attaching syslog.

Comment 8 John W. Linville 2010-03-04 19:35:59 UTC

The madwifi stuff is a distraction, please don't post it unless someone requests results from specific testing.

Are you still experiencing this issue with 2.6.33?

Comment 9 Julius 2010-05-03 02:02:29 UTC

Hello,

I just installed compat-wireless 2010-04-26 and I cannot get a connection. I'll include more information or debug logs if desired.

Comment 10 Julius 2010-05-03 02:07:03 UTC

My cards pci-id is 168c:0012 so it's a AR5211

Comment 11 John W. Linville 2010-08-13 15:46:21 UTC

I never got an answer from comment 8, so I'm closing this.  Please reopen if the problem persists with 2.6.35 (or later) kernels.
