How to reconfigure wifi after mistake?
My wifi was suffering badly in the past week. Very slow speeds and lots of interruptions. I know found out that the problem was with the modem and not with Ubuntu.
In the mean time I used this answer to remove my intel driver and reinstall it. BUT it failed. It left me without a functional driver. I tried running modprobe, reinstall the kernel, copying the backup files of the drivers back, all to no avail.
Now I'm left without a network adapter, and without a functional driver.
How can I restore the system to its original state?
Background:
lspci -nnk | grep 0280 -A3

You installed backport-iwlwifi which evidently was incompatible in some way with your Ubuntu version. It was suggested that you uninstall it:
cd backport-iwlwifi
sudo make uninstall
Uninstalling the backport package allows the original in-kernel modules to reclaim your device.
