Same problem. I see networks, sometimes i can connect! Sometimes can not. If i run few times this script, then i can connect, not every time. But it's better than nothing. Run as root or with sudo:

-------------------------------------------------
ifconfig wlan0 down
rmmod -f rt2800pci
modprobe rt2800pci nohwcrypt=1
ifconfig wlan0 up
------------------------------------------------

options rt2800pci nohwcrypt=1 probably not a special trick.
