If you haven't found a driver for your Ralink wireless network device under Ubuntu, then this tutorial may be useful for you. We will help you install drivers for the following currently supported wireless network adapters:

  • RT3090
  • RT3092
  • RT3390
  • RT5390
  • RT5392 
Under Ubuntu 11.10 or any older version, open the terminal and install this PPA and the dkms package with the following commands:

sudo add-apt-repository ppa:marko-techytalk.info/ralink-wireless

sudo apt-get update

sudo apt-get install rt5390-dkms

To prevent your Kernel from loading undesired driver modules (not the rt5390sta kernel module), then edit the /etc/modprobe.d/blacklist.conf file with this command:

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

At the end of the file, add these lines:

# Blacklist conflicting kernel modules
blacklist rt2800pci
blacklist rt2800lib
blacklist rt2x00usb
blacklist rt2x00pci
blacklist rt2x00lib
blacklist rt2860sta
blacklist rt3090sta

Press CTRL+Q and save your file, then reboot your system. You can now test your wireless network adapter. For any bug or updates, you may check the creator's repository here.
