Bug Description

Reproducible in Lucid/10.04 since 2.6.32-9.13
Not reproducible in Karmic/9.10 (note: linux-backports-modules-karmic-generic *not* installed)

Periodically my wireless device (ar9170-based, usb, 0846:9010 NetGear, Inc. WNDA3100 802.11n) spews phy2 errors in the kernel ring buffer (easily seen in dmesg output) after which I must remove it and reinsert it for it to reassociate with the wireless access point and obtain a dhcp lease.

This symptom occurs regardless of access point (manufacturer, open/wep/wpa/wpa2) configuration. I am able to reproduce this symptom on Cisco, Netgear, D-Link access points both with and without stock manufacturer firmwares.

I'd like to add that I see the same with my NetGear, Inc. WN111 v2 802.11n USB dongle (came packaged with the DG2100N ADSL router). This device uses the same driver and firmware (apparently -- since I found this bug via google).

If I can provide more information than just a "me too", please let me know.

I'm also seeing it on 10.04, kernel 2.6.32-22-generic

Daniel T Chen, 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

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

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.
