Message #107791
[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.

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.
