Warning: no configs for USB devices found!

Have you been using this r8168 network profile the whole time?

I also noticed that what is loaded is 8169.

So you could try blacklisting/removing that module to see if another is used, example:

printf "blacklist r8169" | sudo tee /etc/modprobe.d/blacklist-8169.conf

And/Or have you tried with it removed?

sudo mhwd -r pci network-r8168

yes, i have been using only r8168.

I ran the first command, but I still don’t get the connection.

The first command would blacklist the module … you would then need to reload things, or simply reboot.

I rebooted, but still doesn’t work

Then remove the file

sudo rm /etc/modprobe.d/blacklist-8169.conf

Also check, just in case, the output of

rfkill list

I did.

i don’t understand your problem. Seems, you are connected to the WLAN via IPv4 just fine. Is it not working or do you want to connect via wired Ethernet? In the later case, disable WLAN (not the complete network, only wireless) in the network manager and the system should switch to Ethernet. Or did i miss something?

If WLAN doesn’t work either, could it be that your provider only supports IPv6?

HP

Hello, I have wireless connection, but when I try to connect to Ethernet it doesn’t work. Of course I disable Wifi before pluging Ethernet cable.

so please disable WLAN, connect the Ethernet cable, wait some 2-3 seconds, then send the output from ifconfig -a then nmcli (as before) and from ‘ping 8.8.8.8’. Also make sure the cable is fine, maybe test with a different cable and with different ports of your internet router.

HP

… also:
run
sudo dmesg -w
in a Terminal while you plug in/unplug the cable
it should register … something when things change

Thank you, I have solved the problem. It was router issue :face_with_open_eyes_and_hand_over_mouth:
