Comment 14 for bug 210725

Forgot to inculde this!
If you tried to compile the Ralink driver before or used ndiswrapper, you should do some steps before compiling the patched version.

Stop networkmanager:

sudo /etc/init.d/networkmanager stop

sudo ifconfig ra0 down ## Or wlan0 instead of ra0 if ndiswrapper was used
sudo modprobe -r rt2860sta ## or ndiswrapper instead of rt2860sta

Remove old config file as User, not root:

rm -fr ~/.gconf/system/networking/wireless/networks/*

Restart, and you should be able to log in a new network..
