Internet is detected, but does not work.

Post by idiotuser » Tue May 15, 2018 9:17 pm

Linux mint. 4.10.0-39 generic x86_64 (64 bit). Cinnamon 3.6.6.

LENOVO (portable) Thinkpad T470.

My internet was working fine before I got home today.

When I plug in the ethernet cable, the computer thinks it is connected without problem. (connected logo shows up)
Similarly, I can connect to the wifi without problem. (connects to the wifi, tells me my connection strength is 82%)

But when I try to visit websites, they get stuck on "Looking up ..." before failing.
The wifi and ethernet are working on other computers in the same house (I am posting from it right now.)

Here are some things I put into the terminal and the output:

Code: Select all

ping -c 3 www.google.com
ping: unknown host www.google.com

Code: Select all

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 2029ms 

Code: Select all

dmesg | grep -i dns
[    1.537468] Key type dns_resolver registered

Code: Select all

sudo service networking restart
(no output, internet does not work)

try this right click on Network Manager Icon and edit connections highlight the wifi one first and edit Under the IPV6 tab switch to ignore.
See if it will connect then. If not I suspect that the problem may be in your router Is there a firewall enabled that you may have to disable or add your machines IP address to in order to gain access?
Also if you could post the output of this command -

Code: Select all

inxi -Fxz
it may be helpful to those trying to diagnose the problem.
