Comment 2 for bug 2022826

More information:
I'm now getting my wired connection option not being available and also not shown with ifconfig. Also, my wi-fi connection hangs on trying to connect. I've tried various answers referred to below.

ifconfig enp2so:
enp2s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

ifconfig shows for wlp3s0:

sudo lshw -C enp2s0 shows nothing

sudo lshw -C wlp3s0 shows nothing

lspci -nn shows for Ethernet:

I found a webpage:
https://tutorialforlinux.com/2021/05...based-systems/

I followed the instructions and installed realtek-r8125-dkms package OK. On rebooting, I followed the instructed procedure (shown when installing the package) of Enrolling a MOK, creating a password and then entering it when requested on the reboot. But worse in that the Wired option is not shown when trying to connect to internet via router. And my WiFi (using Router) is not working so I'm posting using my Android phone as a Hotspot. Will I have any hair left soon!

I've found another webpage:

I've tried both answer 1 & answer 2. Still no improvement after either.
