I have a Lenovo Thinkpad T420, with "Intel(R) Centrino(R) Advanced-N 6205 AGN"
wireless card. wheezy is installed. I sometimes connect to one of two
different wireless networks, both unsecured (I configure the wireless through
/etc/network/interfaces). In both instances, the connection will drop several
times per day, without any provocation. Another wheezy install on different
hardware had no such problems. I imagine the issue is with the wireless card,
as that seems to be the most relevant hardware difference between the new laptop
and the old laptop.
The network interrupts are strange, in that they leave essentially no
trace in 'dmesg'. Things do register via 'iwevent':
2011-07-13 22:08 [root@******* miforbes]# iwevent
Waiting for Wireless Events from interfaces...
23:27:39.200445 wlan0 New Access Point/Cell address:Not-Associated
after this event `iwconfig' shows no essid associated with wlan0:
2011-07-14 20:23 [~]$ /sbin/iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
wlan0 IEEE 802.11abg ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=15 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:off
The "normal" output of 'iwconfig' is:
2011-07-14 20:44 [root@********* miforbes]# iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
wlan0 IEEE 802.11abg ESSID:"********"
Mode:Managed Frequency:2.412 GHz Access Point: **************
Bit Rate=48 Mb/s Tx-Power=15 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
Link Quality=43/70 Signal level=-67 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:61 Missed beacon:0
so it seems like the signal strength is decent.
Restoring the essid with 'iwconfig wlan0 essid ******' fixes the
problem, no need to even restart dhcp. Interestingly, the last thing that
appears in dmesg before the disconnect is always

(the below dmesg output has this happen twice, note the afs server
losing internet access).
Various searches indicate to me that cfg80211 is reseting the
connection, and that this is causing the problem. However, I cannot
identify why it is being called.
I have tried several things to fix this. I've tried the options:
options iwlagn 11n_disable=1 11n_disable50=1
as well as
options iwlagn swcrypto50=1 swcrypto=1
and
options cfg80211 ieee80211_regdom=US
in modprobe.d conf files (currently these are all enabled). Initially crda was not even installed, and I
took this as the reason the wireless was failing, that is the dmesg just
showed:
[12626.267794] cfg80211: Calling CRDA to update world regulatory domain
[12758.689580] afs: Lost contact with file server 18.9.60.13 in cell athena.mit.edu (all multi-homed ip addresses down for the server)
[12758.689590] afs: Lost contact with file server 18.9.60.13 in cell athena.mit.edu (all multi-homed ip addresses down for the server)
without crda actually being run. So I installed
crda.deb and iw.deb from the repository, but this only produced more verbose output in dmesg
with regards to what crda was doing.
I have also upgraded my firmware from the version in wheezy, to the latest
version from the firmware homepage http://intellinuxwireless.org/.
The disconnects seem to happen during network inactivity as well as
activity (including leaving a ping running).
I thought at one point it might be some sort of power management issue, but this
doesn't seem to make sense given the reliable connection to cfg80211, which I
don't think has a connection to power management.
It seems likely (but I haven't tried) that a network configuration daemon (networkmanager,wicd) could
solve this problem by reconnecting on each disconnect, but this seems to only
mask the issue.
I've had a remarkable lack of success in finding similar bugs, and am not
entirely sure that cfg80211 is actually the problem. However the following
URL's seem vaguely similar to my problem:

http://www.devheads.net/linux/fedora/user/how-can-i-stop-network-scan-cfg80211.htm
Any help would really be appreciated.
