There are a lot of warning traces from mac80211.c. The other interesting thing is the following: [ 367.389096] wlan0: deauthenticating from 00:03:52:e3:0e:10 by local choice (reason=3D3) [ 367.416312] cfg80211: Calling CRDA to update world regulatory domain [ 369.367667] wlan0: direct probe to 00:03:52:2c:01:00 (try 1/3) [ 369.565008] wlan0: direct probe to 00:03:52:2c:01:00 (try 2/3) [ 369.764891] wlan0: direct probe to 00:03:52:2c:01:00 (try 3/3) [ 369.964768] wlan0: direct probe to 00:03:52:2c:01:00 timed out [ 381.310339] wlan0: direct probe to 00:0f:61:1a:0c:50 (try 1/3) [ 381.508071] wlan0: direct probe to 00:0f:61:1a:0c:50 (try 2/3) [ 381.707955] wlan0: direct probe to 00:0f:61:1a:0c:50 (try 3/3) [ 381.907788] wlan0: direct probe to 00:0f:61:1a:0c:50 timed out [ 393.250073] wlan0: direct probe to 00:03:52:2c:01:00 (try 1/3) [ 393.447810] wlan0: direct probe to 00:03:52:2c:01:00 (try 2/3) [ 393.647700] wlan0: direct probe to 00:03:52:2c:01:00 (try 3/3) [ 393.847576] wlan0: direct probe to 00:03:52:2c:01:00 timed out [ 405.183177] wlan0: direct probe to 00:0f:61:1a:1d:30 (try 1/3) [ 405.380906] wlan0: direct probe to 00:0f:61:1a:1d:30 (try 2/3) [ 405.580773] wlan0: direct probe to 00:0f:61:1a:1d:30 (try 3/3) [ 405.780658] wlan0: direct probe to 00:0f:61:1a:1d:30 timed out There is another thread title "iwlagn is getting very shaky". It makes me wonder. Where did you get your kernel from. From you dmesg I see: Linux version 3.1.0-rc6-gbee709a (nico@brief) I tried to locate the SHA1 bee709a but it is not in my repository. I want to look what the warnings from mac80211 mean. Gr.
