Wifi Disappears Fix
Recently got the Alpha 15 B5eek. Had a random BSOD and then afterwards my wifi disappeared from the laptop. Tried rvery fix under the sun. From drivers to reinstalling windows. It became obvious that it was a hardware problem. Was going to get a new one under warrant but tried this fix and it worked. Probably obvious and well know but it took me forever to find.
Unplug everything from laptop, including AC. Press and hold power button for at least 60 seconds (use a timer). Give it time to be shut down. Power it back on and all the hardware should reset itself. My wifi reappeared.
