Comment 13 for bug 594866

I tried something more in the KISS idea today: download the daily-live amd64 and did this:

ifconfig wlan0 down
lsmod | grep rt
rmmod rt2800pci
rmmod rt2860sta
rmmod rt2800lib
rmmod rt2x00usb
rmmod rt2x00pci
rmmod rt2x00lib
modprobe rt2860sta
ifconfig wlan0 up

and then I could connect to my WPA protected wireless network, still in the live image. Will try the installed system later.
