Trouble with Ubuntu 20.04 and a TouchSmart 310PC

As soon as I updated to 20.04, my wifi started getting dodgy. It was rather annoying as it was intermittent. I had recently updated from 18.04 (32 bit) to 20.04 (64 bit). I have no idea why I using 32 bit software, but the upgrade solved more problems and 20.04 is obviously nicer. Running back to 18.04 (32 bit) was not optimal, so I needed to get this fixed. 

It turns out that 20.04 doesn't have the kernel module for a Ralink RT3090 wifi card loaded, but it is available. Sigh.  

You need to do it manually like so: 
echo "options rt2800pci  nohwcrypt=1" | sudo tee /etc/modprobe.d/rt2800pci.conf
sudo modprobe -rfv rt2800pci
sudo modprobe -v rt2800pci
