http://www.dailylinuxnews.com/blog/2014/09/install-ralink-rt3290-wifi-driver-in-ubuntu-linuxmint-elementaryos/

From the link:

1. Before installing we need to install the package called dkms which can be done by running the following command,

    sudo apt-get install dkms
   

2. Download the package from this link at your own risk.

3. Now open terminal and browse to the directory to which you downloaded the file in the previous step. Lets say that you downloaded it to your “Downloads” directory. If so then you can browse to the “Downloads” directory by running the following command,

    cd $HOME/Downloads
   

4. First we have to extract the file rt3290sta-2.6.0.0.dkms.tar into the directory /usr/src. To do that, run the following command from the directory which has the tar file

    sudo tar -xvf rt3290sta-2.6.0.0.dkms.tar -C /usr/src
   

5. Browse to /usr/src directory,

    cd /usr/src
   

6. Now we install the patched driver using the following command,

    sudo dkms install -m rt3290sta -v 2.6.0.0 --force
   

7. Restart the computer and the WiFi should be working.

Steps to Remove

In case if this issue is fixed in the kernel and then you want to to remove the patched driver completely, run the following command and restart the system.

sudo dkms remove rt3290sta/2.6.0.0 --all

Note:

If you face problem after a kernel update, then remove the driver, reboot the system and then install the driver, reboot the system again.
