I apologize for the late response. First, try connecting your computer to the ethernet. Next do run the command in the terminal:
sudo apt-get update
sudo apt-get firmware-ralink
This would automatically install the rt2800pci kernel module which would support multiple Ralink's wifi adapters including the RT3290.
Reboot your system afterwards and you should be able to connect to wifi. If not try:
sudo modprobe rt2800pci
Though it should automatically load into the kernel using the above two commands. If you have any problems, feel free to contact me.
My Setup: HP Notebook: HP 14-dk0028wm Current Operating System: Ubuntu 20.04 LTS
