Wired network shows connected, but internet doesn't work.

sudo lshw -C network

shows following in terminal :

I also tried by disabling secure boot, but it doesn't work too.

on ifconfig it shows :

Note:) I have read most of similar threads/questions here before asking this. None of those works for me

Please help me resolve this issue.

  • You do not have ip address on enp1s0. Do you have dhcp server on wired network? – 2707974 Oct 2 '17 at 7:05

    If you don't have dhcp server on lan you must provide ip, nm, gw and dns manually for wired connection. – 2707974 Oct 2 '17 at 8:32
  • yes dhcp on wired network. – mcjoshi Oct 2 '17 at 13:59
  • Can you give me output from command nmcli connection show enp1s0 – 2707974 Oct 11 '17 at 8:23
  • It says : Error: enp1s0 - no such connection profile. – mcjoshi Oct 11 '17 at 8:43

What happens when you do the following?

sudo /sbin/modprobe -v -r r8169
sudo /sbin/modprobe -v r8169

If your r8169 comes back into service, then:

Had your machine previously suspended?  That is a well-known weakness

in the r8169 kernel object: suspend followed by resume seems to disable the r8169 driver for some reason, going back a few years.
The 2 command lines above work-around that.
I wound up creating a systemd service to automate the work-around for my laptop.

  • After trying this it just prints : rmmod r8169 and rmmod mii.. Athought when i connect my pc to a router using lan cable, it works... but when i connect it to port directly, it shows connected to wired network but internet doesn't work – mcjoshi Oct 18 '17 at 7:00
