It is hardly used, hasn't had the right name in a long time, is getting a huge amount of spam etc, but more importantly most iwlwifi issues are discussed on linux-wireless (&lt; at &gt;vger) anyway. When this list is used, it's usually just one of many CCs. Additionally, there's the ilw email alias to reach the driver maintainers.

What happens is that my intel 6300agn wifi card drops the connection after a certain amount of time (usually 45m to 2h), if it connected to a 802.1X network. I tested this on two different 802.1X networks, both configured as EAP- TTLS+PAP+TKIP. One of them showed very predictable disconnects after exactly two hours, the other does not seem to be predictable. It also affects a bunch of other notebooks with different intel wifi cards. Note that when I say "drops the connection", I mean that no data packets can flow through wlan0 anymore (no ping, all connections drop), but wpa_supplicant still "thinks" it is connected. Restarting wpa_supplicant fixes the problem. It was a huge pain in the ass to bisect, but I eventually found the first bad commit: commit 5a3d9882b84edf5fa8e8ca33a5d6df25e2e727a5 Author: Johannes Berg &lt;johannes.berg&lt; at &gt;intel.com&gt; Date: Fri Jul 15 13:03:12 2011 -0700 iwlagn: rewrite HW c</pre> Fabian Henze 2012-01-31T22:38:40 http://permalink.gmane.org/gmane.linux.drivers.ipw3945.devel/7597 <pre>Hey Dave, Can you please try to patch attached to this thread.

I can see you are hitting PASSIVE_NO_RX, meaning that the uCode complains that you are trying to Tx on a passive channel on which it hasn't heard any beacon yet. But then we finally get a beacon there, and open the queue again. Anyway, can you try the attached patch ? Note that I have no real way to test it (I have to admit I haven't even compiled... I am not in my office). I hope it might help. ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!

Since Intel has stopped supporting iwl3945, no firmware fix has been possible. It has been workarounded by disable_hw_scan=1 as default, with the penalty of network performance being lower and frequent 'hangs' on the connection. I was able to trigger the firmware error by doing "iw dev wlan0 scan passive". By comparison, "iw dev wlan0 scan" does NOT trigger the firmware error. Having activated firmware debugging, it would seem a firmware error occurs when a full passive scan is done. If all channels 1-140 are scanned passively, a firmware error occurs. If at least one of those channels is actively scanned, no error occurs. Where should I look next?
