rt2400pci unusably low bandwidth

[Alejandro Mery]

Binary package hint: linux-image-2.6.27-7-generic

This was supposed to be fixed in 2.6.25 but it was not. The offered solution is to build the rt2400 "legacy driver" by hand, but that isn't a solution on a distribution "for humans".

in 7.10 it detected 54Mb/s as all there other machines in the house, now only 1Mb/s and in 8.10 it doesn't accept to be set to anything higher than 11M

I have the very same problem, but with the ath9k-driver (AR5008).

Got the same problem with rt2500pci, the speed is only 1Mb. Executing 'sudo iwconfig wlan1 rate 54M' sets the rate to 54Mb:

Hi mnemoc,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/karmic . If the issue remains, please 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 289811

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.

you have to be kidding us. after more than 17 months since the report
