how to install rt73 driver for dwl-g122 rev. c1 in ubuntu

For C1 version (ID 07d1:3c03) you use the ralink chipset driver (use lsusb command to see).

Steps for install:

1. start the system with the device disconnected to avoid conflicts

2. install the correct driver

- download serialmonkey driver: http://rt2x00.serialmonkey.com/rt73-cvs-daily.tar.gz

- extract and install (read file README for details). To install execute in the console:

cd /driver-folder/Module
sudo make
sudo make install
sudo modprobe rt73

3. unloads the modules in the system start that do not work correctly (use lsmod command to see while device is connected)

- edit file /etc/modprobe.d/blacklist:

sudo gedit /etc/modprobe.d/blacklist

- adds the lines:

# causes the conflict with the correct driver rt73
blacklist rt73usb
blacklist rt2570

4. connect the device and temporally unloads the modules to avoid to restart:

sudo rmmod rt73usb
sudo rmmod rt2570

5. if there is not errors, configures your connection with the network administrator and ready

This is the sort of thing that is best suited to our Tutorials section. I am closing this in the hope that you will submit it there.
