I bought a new USB wifi adapter after my old one broke down. The one I bought was recommended as working on Linux but it’s not. I have no wifi at all. Wifi adapter is tl-wn722n

Try another usb port and then do lsusb again.

Looks like you got the RealTek one as described in the amazon review

Driver is here
it requires me to compile the driver which i dont know how to. What now?
Compiling is easy, its troubleshooting code that wont compile that can be hard.
If you dont want to compile the drivers you could return the adapter for a different one.
ive lost my waranty.
You should already have DKMS.
sudo apt install git
git clone https://github.com/lwfinger/rtl8188eu
cd rt18188eu
follow the instructions from there and see where you get.
Or just install windows to use the adapter.
/s
couldnt help myself
So it somehow fixed itself after i plugged in and unplugged ethernet cable which was connected to my laptop with wifi, do you know what happened?
Well before when you did lsusb it wasnt even showing up so maybe it was just a fluke or bad usb connection.
I came here to post this,
Sold these at the shop I used to work at, customers had trouble running on linux and this always worked.
Seems like it’s fixed now.
