I had a similar problem with a Ralink-driver (2570). See bug https://bugs.launchpad.net/ubuntu/+bug/237144.
I was able to get my network running again by downloading the latest drivers from serial-monkey http://rt2x00.serialmonkey.com/wiki/index.php?title=Main_Page.
I looks that the proper driver is not shipped with the kernel, so I have to recompile the project each time I upgrade to a new linux-kernel
