Bug#677880: iwlwifi: flakey and slow connection, high invalid misc count
Hi. Done. http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2370 The problem is that I think it fails too using WEP encryption. In the dmesg attached you can read: [35089.612272] BUG: Bad rss-counter state mm:880133a4db80 idx:1 val:-2 [35089.612283] BUG: Bad rss-counter state mm:880133a4db80 idx:2 val:2 Thanks for your time Victor.

Bug#677880: iwlwifi: flakey and slow connection, high invalid misc count
Source: linux-2.6 Followup-For: Bug #677880 Dear Maintainer, *** Please consider answering these questions, where appropriate *** Hi there. First, thanks for your time. It seems to be fixed in Linux version 3.4-trunk-amd64 (Debian 3.4.1-1~experimental.1) (debian-ker...@lists.debian.org) (gcc version 4.6.3 (Debian 4.6.3-1) ) #1 SMP Wed Jun 6 10:34:53 CEST 2012 I have tested wifi at home and at work without options. At home (WEP): The invalid misc count goes up very slowly, it has connected without any problem and it has been 1h without disconnecting. Besides speed is always 54 Mb/s and it does not change. At work (no encryption): It does not work without options cfg80211 ieee80211_regdom=EU INFO: Now I'm at home. I think I've turned on encryption at home after I started having problems with wifi. Let me disable encryption and try again. Maybe this is the cause ... :-( Thank you !!! *** End of the template - remove these lines *** -- System Information: Debian Release: 6.0.5 APT prefers stable-updates APT policy: (700, 'stable-updates'), (700, 'stable'), (400, 'testing'), (50, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 3.4-trunk-amd64 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

Since it was an n issue I am now using the second one just for wifi (the first one hangs and has some other problems when I enable its wifi support, although only with linux). The wifi problem I reported has dissapear (it occurs once a week or so) after I upgraded the Lenovo W500 to 3.3.4-1~experimental.1 and decided to install compat-wireless-3.4-rc3-1.tar.bz2 from http://linuxwireless.org/en/users/Download/stable/#compat-wireless_3.4_stable_releases At first it was an small improvement (it disconnected 2~3 times each hour) but then I played with options and with options iwlagn ack_check=1 fw_restart=1 11n_disable=1 bt_coex_active=0 options iwlwifi ack_check=1 fw_restart=1 11n_disable=1 bt_coex_active=0 options cfg80211 ieee80211_regdom=EU it now disconnects once or twice a week. I think Olivier found the same solution for his problem in http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=668547#40 The strange thing is that I've made the options change only in the Lenovo machine, the other machines disconnect once or twice too without any change. I should have tested more, but since it works and I do not know which is the problem I decided to stop making changes. Just let me know if you want me to test something else. If not I think bug should be closed.

Thanks again for your work on this. Please try a 3.4.y kernel (with the stock wireless drivers) from experimental with (1) no special parameters and then (2) whatever parameters seem appropriate to you and let us know the result of each.
