The bluetooth/WiFi adapter (Marvell Avastar 350N (88W8797)) from the Surface Pro is not working anymore. It was working fine a couple days ago. I followed this user's post and it still wouldn't work. I have tried different fixes that I could find here on the forums but nothing worked.
Could it be related to Ubuntu turning it off to save power? On windows I was having the same issue and I disabled that option and it immediately started working again.
