Bug Description

this problem comes and goes since 9.04, bit rate goes from 54MB/s to 1MB/s very dinamically... even at 1 meter of the AP. It was quite decent in 10.04 but I upgraded to 10.10 and it's close to unusable again. `sudo iwconfig wlan0 rate 54M` solves the problem during a few minutes only. linux-backports-modules-wireless-maverick-generic didn't help either.

Alejandro Mery, thank you for reporting this and helping make Ubuntu better. 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? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

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

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

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
