I also noticed that this actually doesn't happen always. It seems to happen only at some locations (might be some weird AP<->wifi interaction).

I'm encountering the same problem. Using iwlagn, wpa_supplicant hangs for a few seconds when the router changes the wpa key. During this time, no network connection is existing. Setting "key lifetime" in the router configuration to a long period, e.g. 60 min, reduces the problem. System: Opensuse 12.1, wpa_supplicant v0.7.3. Log: WPA: Key negotiation completed with 00:0f:b5:18:b4:11 [PTK=TKIP GTK=TKIP] CTRL-EVENT-CONNECTED - Connection to 00:0f:b5:18:b4:11 completed (auth) [id=0 id_str=] WPA: Group rekeying completed with 00:0f:b5:18:b4:11 [GTK=TKIP] CTRL-EVENT-DISCONNECTED bssid=00:0f:b5:18:b4:11 reason=15 Trying to authenticate with 00:0f:b5:18:b4:11 (SSID='xxxxx' freq=2457 MHz) Trying to associate with 00:0f:b5:18:b4:11 (SSID='xxxxx' freq=2457 MHz) Associated with 00:0f:b5:18:b4:11 WPA: Key negotiation completed with 00:0f:b5:18:b4:11 [PTK=TKIP GTK=TKIP] CTRL-EVENT-CONNECTED - Connection to 00:0f:b5:18:b4:11 completed (reauth) [id=0 id_str=] WPA: Group rekeying completed with 00:0f:b5:18:b4:11 [GTK=TKIP] CTRL-EVENT-DISCONNECTED bssid=00:0f:b5:18:b4:11 reason=15 -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I have an Intel Centrino Ultimate-N 6300 [8086:4238] (rev 3e) with a 802.11g AP in WPA-PSK mode and I'm using kernel-desktop-3.1.0-1.2.1.x86_64. This is a regression over 11.4 where everything is working fine. I've tried the 11n_disable=1 option as suggested in similar reports but that did not bring any improvement. I'll attach iwevent and kernel messages as well as the wpa_supplicant logfile which cover one hour this morning during which the connection stalled four times at 10:32, 10:42, 10:57, and 11:11. I can reproduce this reliably so please let me know if you need further info. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Is this still reproducible with latest kernel. Like from kernel:head or kernel:stable: http://download.opensuse.org/repositories/Kernel:/HEAD/standard/ http://download.opensuse.org/repositories/Kernel:/stable/standard/ ?

If so, I suggest to report this on intel wireless (ilw@linux.intel.com) and linux wireless (linux-wireless@vger.kernel.org) lists.

Running kernel 3.1.9-1.4, the problem described in #5 does not occur anymore, even without using the workaround "swcrypto=1" provided by #10.
