This even happens with distribution and the latest kernel 2.6.36. It is possible to reduce the frequency by using ping but it doesn't fix the problem. Often only removing the iwlagn module and adding it again fixes the problem. With 2.6.36 in general but also in openSUSE 11.4 it is even worse and ping doesn't help at all. It seems to be a firmware problem since the latest one http://intellinuxwireless.org/iwlwifi/downloads/iwlwifi-6000-ucode-9.221.4.1... fixes the problem for me. Atm openSUSE 11.4 has the same 6000. firmware as 11.3 Since the api is compatible it should even be easily possible to fix the bug in 11.3 too through updating the firmware. According to similar bug reports (http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2214) it doesn't happen all the time with this card and every router but it is known and like I mentioned fixed at least in my case with the latest firmware. dmesg output: [ 144.276155] iwlagn 0000:02:00.0: Received BA when not expected [ 144.311555] iwlagn 0000:02:00.0: Received BA when not expected [ 144.427298] iwlagn 0000:02:00.0: Received BA when not expected [ 144.444577] iwlagn 0000:02:00.0: low ack count detected, restart firmware [ 144.444582] iwlagn 0000:02:00.0: On demand firmware reload [ 144.534753] iwlagn 0000:02:00.0: Stopping AGG while state not ON or starting [ 144.534759] iwlagn 0000:02:00.0: queue number out of range: 0, must be 10 to 19 [ 169.235024] iwlagn 0000:02:00.0: Aggregation not enabled for tid 0 because load = 0 lspci output: 02:00.0 Network controller: Intel Corporation Centrino Ultimate-N 6300 (rev 35) Reproducible: Always Steps to Reproduce: 1.Get a laptop with Intel N 6300 WLAN card (for example Thinkpad X201) 2.Use the 2.6.36 Kernel because the frequency of connection dropping is much higher with it 3.Use the Internet or ping to check when it fails Actual Results: After some time the connection drops and you can't access the Internet or router anymore Expected Results: No connection problems at all. -- 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.
