I was following random tutorials attempting to create a private Wifi network on my laptop that would forward my ethernet internet connection on my laptop to other devices on my private network. Clearly I didn't know what I was doing and after some really poor attempts I attempted to undo all my changes and at the moment I'm still suffering from the issue of trying to get my wireless interface to connect to my wifi again. For now I can only use USB/Ethernet tethering to connect to the internet.
However the network interface is still listed and recognizable.

I can attach additional info upon request, can show running services too. Lost links of all tutorials I attempted (sorry) but here's two of them:

I know this is a software (most likely driver) issue because I dual boot on this computer and on my Windows OS I can still access the internet.
Thanks again!
