Hi,
You need to install firmware files in /etc/Wireless/RT61STA directory. You can download all .bin files from the drivers site or it may be there in source code itself. Don't forget you need to configure rt61sta.dat file and put in same directory. Here listing from my system:
Code:
ls /etc/Wireless/RT61STA
rt2561.bin rt2561s.bin rt2661.bin rt61sta.dat
