Output of

ping -c3 google.com
ping -c3 8.8.8.8
ip a
cat /etc/resolv.conf

(as text, please).

Thank you for replying
it says:

" # Generated by NetworkManager

nameserver 213.46.172.39 "

If you don’t provide all the detail I asked for then I can’t help you.

If you change your mind and do want help, then also add ping -c3 213.46.172.38 to the list above.

sorry i interpreted your request wrong:
here are the outputs:
ping -c3 google.com:
Name or service not known

ping -c3 8.8.8.8:
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
— 8.8.8.8 ping statistics ----
3 packets transmitted, 0 received, 100% packet loss, time 2054ms

ping -c3 a:
Name or service not known

ping -c3 213.46.172.38:
PING 213.46.172.38 (213.46.172.38) 56(84) bytes of data.

So apparently you don’t have an active connection or don’t have an IP address (which the output of ip a would have confirmed).

Check your cable and your router.

Otherwise, you’re doing something else, like using a VPN, that you’re not telling us about.

The internet works with windows (i have it on the same machine) and i don’t have any VPN installed, so i don’t think it’s because of that

oh sorry i typed ping -c3 a istead of ip a

ip a output is (for the eth port i use right now):
ling/ether 00:50:8d:b2:39:df brd ff:ff:ff:ff:ff:ff
inet 192.169.1.160/24 brd 192.168.1.255 scope global dynamic noprefixroute enp4s1
valid_lft 2048sec preffered_lft 2048sec

That looks wrong, should very likely be 192.168.1.160. Check your router.

10

oh i’m sorry. it is 192.168 i mistyped it

and also i’ve read on the internet that there are problems with my internet card on kernel 5+

Just a tip:
You can select the output from terminal using your mouse and then press Ctrl+Shift+C to copy text from terminal. That text can be pasted here using Ctrl+V.
Similarly, if you need to paste commands into the terminal, then copy from web browser using Ctrl+C as usual, and then in the terminal, press Ctrl+Shift+V to paste.
This will help avoid errors.

What kernel are you using? You can type uname -r if you don’t know exactly.
Is r8168 (or r8169) installed?

13

yea i know… but i cannot post it here when the internet on my pc isn’t working

Please run command

lsmod | grep r816

and show the result.

Last time I used the lts kernel, the r8168-lts wasn’t installed and I had to do it myself.

17

the output is:
r8169 102400 0
libphy 102400 2 r8169,realtek

18

and how do i do that? (i mean i know how, but without internet)

19

Edit file /usr/lib/modprobe.d/r8168.conf to blacklist r8169 instead of r8168. Then reboot and see if your ethernet works.

in modprobe.d there is no r8169.config
