Ralink RT2571WF
The RT2571WF Wi-Fi chipset can be found in the following devices:
- D-Link DWL-G122 (not rev E1 !)
- D-Link WPA-110
Drivers are included in Linux kernel > 2.6.29, but firmware must be downloaded from serialmonkey website at this address.
Kernel configuration
- Wireless network must be configured by selecting these options in make linux-menuconfig:
[*] Networking support --->
Wireless --->
<*> Generic IEEE 802.11 Networking Stack (mac80211)
- Finally, select the chipset :

<M> Ralink rt2501/rt73 (USB) support
Wi-Fi configuration
First mount the module:
# modprobe rt73usb
Then copy the firmware named rt73.bin (found in Module directory of rt73-cvs archive) in apf /lib/firmware directory. If /lib/firmware doesn't exist create it.
mkdir -p /lib/firmware tftp -g -r rt73.bin <yourIP> mv rt73.bin /lib/firmware
Your Wi-Fi module driver is ready, you can now connect the dongle and after go further with the Wi-Fi configuration.
