Overall, a very good dongle.
WPA/PSK and WEP works flawlessly.
WPA2 works to some extent (occasionally loses connection)
|What doesn't work:|
I have noticed using WPA2 (as with all distributions of Linux). Occasionally the network will appear to drop, and it will be impossible to obtain a carrier signal from a router for a short while, even after rebooting and resetting the router.
|What was done to make it work:|
When hot-plugged, i have found that all kernels as of =>2.6.31 will forcibly load the wrong modules causing a collision, resulting in non-working hardware.
Easy fix for driver collision is this;
Add the following lines into /etc/modprobe.d/blacklist.conf
Then unload those modules (or just reboot) and hotplug the wifi dongle, and check `lsmod | grep rt2' for the rt2870sta module. If it is the only one listed, then WPA/PSK and WEP connections should work flawlessly.
Recommend to reconfigure router to WPA/PSK in order to get a perfect and secure wifi connection.
Another thing to take note of, is that the windows(xp) version of the driver works via ndiswrapper, but only use it as a last resort.. i have noticed the transfer speed to almost drop 50% when downloading files compared to the native linux driver.
