[Bug 1296504] Re: iwl3945 wireless connection becomes unreliable
Ok, I swapped out my old Intel 3945abg card with a new intel 5300bgn wifi card. Reliability seems to have increased, but problem still occurs. See attached for dmesg output of dropout with new wifi card installed, including two instances of wireless disabled by hardware switch. It leads me to believe that the problem was at least partially hardware... I will test the new mainline kernel and report back... ** Attachment added: dmesg output with recurrence after hardware swap https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1296504/+attachment/4429004/+files/dmesg.txt ** Summary changed: - iwl3945 wireless connection becomes unreliable + intel wireless connection becomes unreliable -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1296504 Title: intel wireless connection becomes unreliable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1296504/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1296504] Re: iwl3945 wireless connection becomes unreliable
ethanay, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-3.XY-rcZ Where XY and Z are numbers corresponding to the kernel version. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-3.XY-rcZ Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags added: latest-bios-a15 ** Description changed: - Dell XPS m1330 with Intel Wireless ABG - - uname -a: Linux ethan-XPS-M1330 3.2.0-60-lowlatency-pae #62-Ubuntu SMP - PREEMPT Tue Feb 25 00:32:18 UTC 2014 i686 i686 i386 GNU/Linux - what I expect: wireless connectivity to be reliable and consistent what happens instead: wireless connection cuts out, recovers, re-establishes connection. sometimes (rare) requires disabling / re-enabling via hardware or software switch. sometimes (more rare) hardware fails completely until reboot (removing and re-inserting module fails -- hardware disappears to the system until reboot). This problem will occur without a suspend / resume cycle. This problem appeared recently, within the last month or two months of kernel updates. I think the next step in debugging would be to test reliability against previous kernel versions. - some relevant dmesg: + some relevant dmesg: keyboard: can't emulate rawmode for keycode 240 iwl3945 :0c:00.0: BSM uCode verification failed at addr 0x3800+0 (of 900), is 0x, s/b 0xf802020 iwl3945 :0c:00.0: Unable to set up bootstrap uCode: -5 iwl3945 :0c:00.0: MAC is in deep sleep!.
