A few days ago, after a Windows update, my wireless adapter disappeared in such a way that i can't even try to look for wi-fi connections.  As it happened with a similar case here in the forum to Andy Mann,  the machine updated and auto-rebooted overnight, and suddenly I had no wireless adapter in the Device Manager, the Network Settings page had no Wireless section, and I thought it was a Windows update problem.

I tried toggling Airplane mode and rebooting a couple of times, but it didn't help. After shutting down the laptop completely and turning it on again, though,  the adapter suddenly came back  - I don't know which adapter comes with my Inspiron 15, 7559.

The problem is, suddenly, today it happened again, i changed rooms in my house and when i arrived at the living room table, everything was as I'd left it, except that again, the wireless adapter has disappeared, I can't see a Wireless section in Network Settings, and a list of available networks to connect to. I'm using a cable at the moment, but this time it shows no signs of reappearing.

Refreshing ("scan for hardware changes" in Device Manager) doesn't make it reappear either; i updated all possible drivers from windows, delll and intel, rebooted several times, tryied turning it off and on as i did last time, even tryied changing places where the laptop is at, tryied some cmd commands that seemed to fix the problem to people that updated from windows 7/8 to 10, but nothing seems to work for me.

How can i fix this? Please help!

System info: Inspiron 7559, Windows 10 (64-bit) version 10.0.15063.
