Comment 27 for bug 429370

For me, the bug was fixed by installing the drivers from ralink, available at:

http://www.ralinktech.com/support.php?s=2

(mine are RT2860PCI/mPCI/CB/PCIe(RT2760/RT2790/RT2860/RT2890, version 2.3.0.0 of 01/29/2010)

Install instructions for who needs them, for the rt2860:

 * unpack the files, say in ~/ralinktech
 * edit the file ~/ralinktech/Makefile, so that shortly after "ifeq ($(PLATFORM),PC)", it reads:

LINUX_SRC_MODULE = /lib/modules/$(shell uname -r)/kernel/drivers/staging/rt2860

 * open a terminal, and enter:

cd ~/ralinktech
make
sudo make install

* restart your computer

Before you start, make a backup of the file

/lib/modules/$(shell uname -r)/kernel/drivers/staging/rt2860/rt2860sta.ko

as it gets overwritten by make install.

You have to redo this everytime the kernel gets updated.
