Since Ralink does not patch the driver and the current version does not work, I provided a patched file that you can download and install following this steps
download the patched file from my private Google Drive directory.
open a terminal (Ctrl+Alt+t) and cd into the folder where the file is downloaded, e.g. cd ~/Downloads.
type
sudo tar -xvf rt3290sta-2.6.0.0.dkms.tar -C /usr/src
to untar the content in a system directory
you should now get a password prompt where you type the sudo password and press Enter.
once the files are all extracted type
sudo dkms install -m rt3290sta -v 2.6.0.0 --force
to install the driver with dkms
enter sudo password again and ensure that install is completed successfully (it will take some time).
reboot.
Enjoy Wi-Fi with your RT3290 :D
