No Wifi adapter found?

Question

I'm using ubuntu 18.4. My system froze and did a reboot, since then my wifi is not working. I tried the solution suggested in this question but to no avail. I have dual boot with windows and it's not working in windows either. Here is the output sudo lshw -class network

I'm voting to close this question as off-topic because this appears to be a hardware issue (board not working) and not a Unix/Linux issue — Stephen Harris, Dec 28 '18 at 15:25

From the output of lsshw, where it says network DISABLED and from the telltale of Windows not working, it seems obvious it is hardware related.

You pressed the hardware switch/button to disable the WiFi adapter service by mistake. Press the switch again. WiFi should come up on its own, if not, reboot afterwards.
