I am brand new to Linux and am having trouble with my PCI Wi-Fi adapter and the drivers associated with it. I recently downloaded the 21.04 version of Ubuntu and made the switch from Windows. Once it installed, my existing PCI card that came with the laptop stopped working (Realtek RTL8111E Ethernet LOM is the device name when I run lspci -nnk | grep 0280 -A3).
When I searched for answers and solutions I found WiFi adapter not found Realtek 10ec:8852 on Ubuntu 21.04 and followed along to no avail or internet. I tried other available forums and solutions (too many to mention here) downloading different drivers and git repos. Now I am afraid I am doing more harm than good. Like I said, I am brand new to the Linux world so be gentle. Below are a few screen captures of a couple of useful commands from the terminal that might give everyone more information.
$ nmcli device

// There was other but didn't seem necessary
How can I get my Wi-Fi working?
ls -R | grep rtworls -R | grep rtlin/libor/lib/modulesyou can find them, I tried starting them but I dont know where to go from there. – The Floating Brain Jan 01 '22 at 05:09
