This is an old revision of the document!
This driver doesn't need to be patched anymore.
ifconfig ra0 down rmmod rt2500 wget http://rt2x00.serialmonkey.com/rt2500-cvs-daily.tar.gz tar -xvzf rt2500-cvs-daily.tar.gz cd rt2500-cvs-xxxxxxx/Module #xxxxxxxxxx is a number which represents the driver date and revision make && make install modprobe rt2500
NOTE: This will download the Enhanced Legacy version of the driver. The Next Generation version will NOT work with Aircrack-ng currently.
Make sure to load the driver with modprobe (not insmod) and to put the card in Monitor mode before bringing the interface up.
You also need the following each time you want to use the device in monitor mode:
iwpriv card rfmontx 1 iwpriv card forceprism 1
The forceprism corrects the power being shown as “-1”. It has to be run each time you run aireplay-ng.
