Installing wi-fi drivers on Ubuntu 12.04 for Ra-link corp

gistfile1.txt

First check your wifi hardware

    $ lspci | grep Network

Download the driver source http://www.ralinktech.com/en/04_support/support.php

Extract the tar file to your home directory, `cd` to the extracted directory

    $  nano os/linux/config.mk

And change the values 

     HAS_WPA_SUPPLICANT=y
     HAS_NATIVE_WPA_SUPPLICANT=y

Now save the file.

Now install it with:

    $ sudo make && sudo make install && sudo make clean

Now you need to blacklist the existing drivers:

    $ sudo gedit /etc/modprobe.d/blacklist.conf

Add the following lines

#Wireless drivers conflicting 
blacklist rt2800pci
blacklist rt2x00pci


Now: 
    $ sudo modprobe -rfv rt2800pci

and:

    $  sudo modprobe -v rt3290sta

And your wi-fi will start working as normal again
