Something like this:
rt2800 firmware not loaded
SIOCSIFFLAGS: Operation not permitted
The raison is that on the firmware has been removed from the 2.6.30 kernel image.
So, ensure you have in /etc/apt/sources.list the following line:
deb http://ftp.us.debian.org/debian squeeze main contrib non-free
If you have not it, insert and give aptitude update...
After give the following:
aptitude install firmware-ralink
This will solve your problem.
Bye.
