You may find that your Belkin F6D4050 (v1 or v2) wireless usb dongle just won't work! Well here's the solution.

The Solution

Note: You need the rt2870 driver which is already included with kernel 2.6.29 and up.

First, use lsusb to check that the device ID number is 050d:935a or 050d:935b (v1 or v2, respectively):

[sdenne@marsrover ~]$ lsusb
Bus 002 Device 003: ID 050d:935b Belkin Components

Now create these two files:


Now add the following to /etc/udev/rules.d/network_drivers.rules (that first file you just created):

ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="050d", ATTR{idProduct}=="935a", RUN+="/sbin/modprobe -qba rt2870sta"

Then add the following to /etc/modprobe.d/network_drivers.conf (the second file you created):

install rt2870sta /sbin/modprobe --ignore-install rt2870sta $CMDLINE_OPTS; /bin/echo "050d 935a" > /sys/bus/usb/drivers/rt2870/new_id

Pay close attention to any occurrence of 935a in the lines you've just added. If your device ID is F6D4050 v1, leave occurrences of 935a as-is with the letter a at the end. If your device ID is F6D4050 v2, change the last letter of 935a to b. The letter must match with the output that you see when you use lsusb.

That's it! Now reboot and you'll have wireless capabilities! woo hoo!

Note: to undo everything that you've just done, simply delete the two files you've created.


The Belkin F6D4050 V1(000) device supports 802.11n (I'm not sure about the V2 device), however using the rt2870sta driver I was only able to connect using 802.11g. The solution to get this working is that you need the RT3572STA driver. As of 2.6.36 this isn't included in the Arch kernel distribution, but you can download it from Ralink's website and compile it yourself.

Before compiling, you need to set some options in os/linux/config.h:


Then compile as usual:

 make && sudo make install

To set it up just follow the instructions about, but substitute rt2870sta for rt3572sta. I was able to use exactly the same netcfg configuration, just replacing wlan0 with ra0.
