I have a USB wifi adapter and I don't seem to make it work. it working before (2 months ago) but now it's not. running
lsusb returns the driver:
Bus 001 Device 009: ID 0bda:b812 Realtek Semiconductor Corp. USB3.0 802.11ac 1200M Adapter
I'm not sure if the adapter is broken or I need a new driver and I looked on the internet and couldn't find and suitable driver for it.
Any help is much appreciated. I have already tried the solution here but didn't work. I think it's for some old drivers
