Seems my solution (turned temporary other problem) I found was to go to Safe Mode, enable it there, not show a change, reboot back to normal, get stuck, try unsuccesfully to load everything a few times, enter repair mode, get stuck on scanning and repair is complete for 5 hours, shut off, restart it, and now eveyrthing works.   On the plus side, I now know where my wifi adapter is in my machine.  Didn't think it'd be so small.
After a 2 hour break of non-use, I returned to find Chrome frozen, and my computer offline. Diagnosis says my WiFi is disabled.  But there's no way to re-enable it because every time I try to enable my WiFi Adapter, it freezes my computer instead. How do I enable my WiFi so I can use the internet? F12 does nothing, and I can't connect through Ethernet. Modem is too far away on a different floor. I'm using Windows 10 Home and have a Qualcomm QCA9377 802.11ac wireless adapter, no Killer.
