HOWTO fix rt2500 in Hardy (bug #190515)

[cpbotha]

On my setup, the iwconfig wlan0 54M (or 11M) only works temporarily. I'm not talking about rebooting (I integrated the necessary invocation with my /etc/network/interfaces), but purely as a function of time spent connected. After a while, speed drops back down to a miserable 70kbytes/s. No amount of iwconfig wlan0 54M (or 11M) can then fix it.

I've now built and installed the legacy rt2500 drivers from the last daily CVS tarball: http://sourceforge.net/projects/rt24...ar.gz/download following the instructions in the initial post.

Things seem to be stable, I'll report back if I find otherwise.

many thanks aykito, i've followed your very simple steps and now my ralink card works like a charm!!

I am trying to follow it on Karmic and got this:

Hi Foxy123,
this bug is supposedly repaired in linux-backports-modules-2.6.28 so in theory you dont need to recompile the drivers again, check the bug documentation

[foxy123]

It is still a problem in Karmic. I will reopen the bug.

I also see poor performance with the rt2500pci drivers, and no better after installing the backports package:

paul@locke:~/downloads/rt2500-cvs-2009041204/Module$ dpkg -l |grep backport
ii  linux-backports-modules-2.6.31-13-generic  2.6.31-13.15                                                Ubuntu supplied Linux modules for version 2.6.

More importantly, I'm also struggling to build the rt2500 module:

Has anyone got the old rt2500 module to build on a 2.6.31 kernel?

no, I cannot.

[foxy123]

I wonder if anyone tried to compile 2.6.32 kernel as the fix is supposed to be there?
