Spent a few hours on this one and it's driving me crazy. My dad has been running Ubuntu 14.04, 16.04 and now 18.04 on his laptop for ages and had no issues with the RT5390 WiFi Adapter.
It was working in 18.04 just fine and then nothing.
It doesn't appear in the output of lshw -C network, just the Ethernet card.

Tried running both answers from this section even though it's horribly insecure.How to install wifi driver Ralink RT3290
Any ideas? Could this be an actual hardware failure since it happened so suddenly? Thanks.
EDIT: As requested here's an output of just lspci -nnk
