ifconfig rausb0 down rmmod rt2570 wget http://homepages.tu-darmstadt.de/~p_larbig/wlan/rt2570-k2wrlz-1.6.1.tar.bz2 tar -xvjf rt2570-k2wrlz-1.6.1.tar.bz2 cd rt2570-k2wrlz-1.6.1/Module make && make install modprobe rt2570
Make sure to load the driver with modprobe (not insmod).
Note that this driver currently does not work on big endian systems, such as the PowerPC. Attempting to run “ifconfig rausb0 up” will cause ifconfig to use 100% CPU power, bringing your system to a crawl and never actually working.
There are reports of the aircrack-ng tools freezing and/or stop working.
Here are a few things to try:
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”).
