ralink rt2501 don't work (can't connect or connection unstable)

[Nicolás Garay Tapia]

apparently it don't happen on ubuntu previous to 8.10, but I only have this information from google, so I can't say if it is a regresion or not.
Note that I'm reporting with the official kernel of ubu ntu 10.4, but I tested with the mainline kernel and the same ocurs.

Hi Nicolás,

If you could also please 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.

Ok, I tested the lattest kernel 2.6.35 rc1 for ubuntu lucid and the daily 2.6.35-999 and in bot the problem continues.
Here is the output of the uname command and an attach of some tests:

Why was changed to expired? I sent all the requested information and noone asked me for more info, Also, the bug is still present on ubuntu kernels.
I understand that it is not an usual hardware, but some other people are speaking about this on aircrack forums, unfortunately they don't report the bug an prefer to buy an other wireless card.

I still have this problem with lucid where my rt2501 doesn't work

Nicolás Garay Tapia, 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.
