Hi Im pretty much noob with phones and any issue I google it but I havent found anything at all... I'm really desperate

I use my LG G2 as a WIFI Adapter on my desktop (USB Tethering) but suddenly when I connect my phone it says "Network cable unplugged". I re-installed the drivers and now the adapter wont even show up.... and windows would show up with "No driver found"

USB Composite Device................Ready to use
CDC Serial............................................ .... No Driver found
LGE Android Phone..........................No Driver Found
CDC ECM............................................... .....No Driver Found

I even installed "LG-Mobile-Driver_v3.13.2" and nothing... I saw some stuff about flashing and stock but I have no idea what is that.... I dont even have my phone rooted nor have apps or games (I just use it for phone calls and facebook) is there any easy way to fix this? Not even installing the drivers from the phone works (it has an option for that)

Im really desperate as I need my desktop with Wifi and cant afford buying an adapter (foreign student here)
