This is an old revision of the document!


This driver doesn't need to be patched anymore.

ifconfig ra0 down
rmmod rt2500
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 <interface name> rfmontx 1
 iwpriv <interface name> forceprism 1

The forceprism corrects the power being shown as “-1”. It has to be run each time you run aireplay-ng.

When to use this driver?

See this message.

If you have a ralink chip in an USB device that chip is a RT2570 or RT73 and you need “rt2570” driver or “rt73” driver, “rt2500” driver is for PCI/PCMCIA devices.

Using legacy drivers (or ASPj mods) interface name is ra0 for PCI/PCMCIA and rausb0 for USB devices, if you have wlan0 and wmaster0 interfaces you are using new rt2x00-mac80211 driver (rt2x00 has various modules, for USB devices are “rt2500usb” and “rt73usb”, unload them and load “rt2570” or “rt73”).
