8086:4222 wireless network very slow after upgrade to Ibex (iwl3945)

[Matija Grabnar]

After upgrading to Ibex I noticed an immediate slowdown in my wireless network connections, affecting everything regardless of protocol.

Rebooting into windows or booting from 8.04 live CD restores previous speed, so it's not a hardware problem.

Also, wired port is not affected, so it's not a general networking problem.

The wireless speed is reduced to around 5-7 % of normal speed (100-150 KB/sec instead of 2M/sec, with the wireless transmitter around 6 feet away). Sometimes, immediately after a reboot, normal speed is achieved for a few seconds,
but is then rapidly reduced back to the same low level.

Matija, this seems to be similar, if not the same as bug 271463. Please have a read on the discussion there (maybe my comment about the WPA/WEP will help?).

Bring up your problem in that topic also.

I tried adding the backport modules, but I see no effect. (Though I see a newer version, which also mentions some changes for iwl3945, is still in proposed). Should I try to install that one from source?

Matija Grabnar, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. 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:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc5

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

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.
