Basically this question is related to How do I get a Ralink RT3290 wireless card working? But I have no reputation to comment there.
Answer in mentioned question successfully get me through driver installation. But then whenever I enable WiFi AND disconnect ethernet (so I assume only when traffic starts going through this connection) I get kernel panic error. How to deal with it?
EDIT: Sorry, I was gonna add more info, but apparently messed up.

Couldn't find smarter way, than just a photo of my screen
