Kernel 3.2 works fine. The first symptom was: "deauthenticating from 00:1f:3f:d0:65:73 by local choice (reason=3)" Then, by using debug=0x43fff as a module parameter, messages like the following are in the log file before the disconnect: I iwl_enqueue_hcmd Sending command SENSITIVITY_CMD (#a8), seq: 0x09CD, 52 bytes at 205[13]:9 I iwl_enqueue_hcmd Sending command SENSITIVITY_CMD (#a8), seq: 0x09CE, 52 bytes at 206[14]:9 I iwl_enqueue_hcmd Sending command SENSITIVITY_CMD (#a8), seq: 0x09CF, 52 bytes at 207[15]:9 I iwl_enqueue_hcmd Sending command SENSITIVITY_CMD (#a8), seq: 0x09D0, 52 bytes at 208[16]:9 I iwl_enqueue_hcmd Sending command SENSITIVITY_CMD (#a8), seq: 0x09D1, 52 bytes at 209[17]:9 Another thing I noticed is that the disconnects are happening (most of the time) every 20 minutes and 18 seconds. The connection is established immediately after the disconnect. This is also not happening with every access point, but unfortunately with the one at home. The logfile of the AP states that my client did not respond in time and ie being disconnected because of that. The access point settings are wpa2 psk, ccmp, channel 1, 11n enabled. According to the iwlwifi module, my card is a 6205AGN, REV=0xB0 . Please let me know if I can help with more information. Best, Philipp Dreimann
