Installation of Ralink RT3290

  • fork this repo
  • cd into it
  • compile the driver
  • install the driver

comand for that (it will ask your user password to apply changes to system):

git clone https://github.com/pkeeper/rt3290sta.git
cd rt3290sta 
make  
sudo make install
sudo modprobe -r rt2800pci 
sudo modprobe rt3290sta

Now you need to make it load on startup. Blacklist the rt2800pci driver in /etc/modprobe.d/blacklist.conf and add rt3290sta to /etc/modules.
