Public bug reported: Binary package hint: linux-ubuntu-modules-2.6.22-14-generic
Wireless works initially and then craps out - maybe after several minutes. The encryption key no longer shows in iwconfig output for my wireless interface (wlan0). I get messages in /var/log/kern.log like: Apr 4 22:26:00 lin4 kernel: [ 695.272000] iwl4965: Microcode SW error detected. Restarting 0x82000000. There appear to be several others related to this (although some of this might be the LED which doesn't come on on my machine at the moment even though wireless does work (at least initially): Apr 4 22:26:00 lin4 kernel: [ 695.772000] iwl4965: Error sending REPLY_BT_CONFIG: time out after 500ms. Apr 4 22:26:01 lin4 kernel: [ 696.272000] iwl4965: Error sending REPLY_RXON: time out after 500ms. Apr 4 22:26:01 lin4 kernel: [ 696.272000] iwl4965: Error setting new configuration (-110).

Apr 4 22:26:03 lin4 kernel: [ 698.272000] iwl4965: Error sending REPLY_TX_LINK_QUALITY_CMD: time out after 500ms. etc etc ------------------------ I'm using a dell vostro 1400 uname -a is: Linux lin4 2.6.22-14-generic #1 SMP Tue Feb 12 07:42:25 UTC 2008 i686 GNU/Linux lspci is: ... Intel Corporation PRO/Wireless 4965 AG or AGN Network Connection (rev 61) ... I'm using gutsy gibbon. lsb_release -rd: Description: Ubuntu 7.10 Release: 7.10 I thought the problem was NetworkManager; but after killing it off and using wpa_supplicant manually I still get the same type of problem. So I *think* the problem is iwl4965 kernel module - ie package: linux-ubuntu-modules-2.6.22-14-generic I ended up on this page: http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1490 I think after first looking at a debian bug report that was similar (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=461924). Comment #9 on the intellinuxwireless.org page recommended I get the latest module code and recompile the modules against my kernel. Which is what I did and everything works smoothly now. In more detail: Went to http://linuxwireless.org/en/users/Download. Downloaded compat-wireless-2.6.tar.bz2. Unpacked - which created folder: compat-wireless-2008-04-04/ with the source code etc. Read the instructions and compiled (you need your kernel headers istalled obviously before you do this). The new modules get installed into: /lib/modules/2.6.22-14-generic/updates/ ie the module for my system: /lib/modules/2.6.22-14-generic/updates/drivers/net/wireless/iwlwifi/iwl4965.ko I think the script moves the old wireless modules into a subdirectory (ie the ones not in the 'updates' section). I ran depmod -a; then did a modprobe on the new iwl4965 and it worked. No more error messages and no more dropouts. If I'm right about this, then I think you guys really really really need to put through some kind of patch. It just looks bad when something sort of works and then falls over and then you have to trudge upstairs and plug a blue cable into your machine. And even now, I avoid gnome NetworkManager even though it may not have been the culprit. If I'm not right about this then... I guess it's red-face time. This may be similar to another bug for iwl4965 #194091.
