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

(no output, internet does not work)
