Help Needed for Ubuntu 20.04

I have some issue with my ubuntu 20.04.

I recently Dual Booted my PC.
I had a issue with Wifi : It was disconnecting and reconnecting every few minutes, so I used this link

I followed the steps mentioned in the Answer by scriptdwarf

Now Ubuntu says there are no Wifi adapters at all
How do I revert back to the previous drivers?
