Wifi and bluetooth disappeared

Wifi adapter disappeared

Product: HP Pavilion G-6 2231Tx
Operating System: Microsoft Windows 10 (64-Bit)

My Wifi adapter suddenly disappeared after a restart. Now it does not appear in the device manager. There is no trace of a Wifi adapter whatsoever left in my laptop. All of this happened over night when the laptop was in shutdown state. I tried installing drivers but even that did not work. I tried to run Ubuntu on a USB to check and found no trace of a Wifi adapter even on Ubuntu. Ethernet works fine but keeps refreshing itself every 10-15 minutes. I've tried restarting the system several times and that is not working. Please suggest a solution to this problem.

When troubleshooting wireless, it's important that your system is fully updated by opening a terminal, CTRL+ALT+T. Using a wired internet connection, please run:
Code:

sudo apt update
sudo apt dist-upgrade

and reboot if necessary.

If the issues persist, it is recommended that you install pastebinit, by running:
Code:

sudo apt install pastebinit

This will enable the wireless script to, upon your approval, upload the obtained data to pastebin, creating at the same time a link to it in your terminal, permitting you to paste it to a forum thread.

Once that's done, download and run the wireless info script, which will gather information to help diagnose your system. You can run it using this command:
Code:

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \
chmod +x wireless-info && \
./wireless-info

It will create the file "wireless-info.txt" at the location it is run from, and depending on its size, an additional archive called "wireless-info.tar.gz". If you prefer, you can post the file directly to pastebin yourself. Sensitive information like MAC addresses and WPA/WEP keys are masked automatically.

If you aren't able to connect to the internet with the affected system, including via a wired connection, just navigate to
