My wifi is working fine. However, when I try to connect using the ethernet, I get no connection. The ethernet is not even present in the settings. I'll list the output of some commands below, along with the things I tried.

ifconfig:

I tried using the network manager through this command: nm-connection-editor. And I added the ethernet connection. However, it didn't work as well.

I tried using this solution, and this one. But nothing worked.

I don't know how, but I have a feeling that this docker connection has something to do with it.

I hope that someone will find a solution. Thanks in advance...

It turns out that your Ethernet is disabled

This may help:

sudo ifconfig enp7s0 up
sudo nmcli dev set enp7s0 managed yes

Then restart NetworkManager:

sudo systemctl restart NetworkManager

We can connect to the Internet via your phone's USB modem or directly plug in the cable for convenience. Then

sudo apt update
sudo apt install -y git build-essential
git clone https://github.com/lwfinger/rtw89.git
cd rtw89
make
sudo make install
sudo mkdir /usr/lib/firmware/rtw89
sudo cp  rtw8852a_fw.bin  /usr/lib/firmware/rtw89/
sudo modprobe rtw89pci

After these steps, you can select Internet in the Wi-Fi menu.
