Linux Mint 20 Wi-Fi adapter cable not plugged in

Unix & Linux Asked on November 17, 2021

this is a self built computer, I have a wifi adapter that works in Windows and has a Linux driver. I have installed it, but no matter what I do the wired cable unplugged in networks is the only item I see. I have to tether on my phone to get internet connection. I have followed the step by step guide on Realtek to install the driver manually and it still will not detect. This is an RTL8111/8168. dkms status seems to have nothing there when executed. I also have a usb bluetooth adapter that is working fine. The wifi adapter is not working.

Here is the rfkill output:

$ rfkill list all
0: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no

Here is the sudo lshw -C network output:

and here is the ifconfig output:

Hi It seems to be a problem with the 5.4 kernel. Install 19.3 Linux Mint with 4.6 kernel and wait until 5.8 kernel comes out.
