without internet in LL 4.8 - I am a new user

Document the issue

1. Can you add a screenshot and / or the exact error message LL sends?
   
2. What is the result, if you have entered the following command in "Xfce Terminal"?
   

Code:

ping -c6 8.8.8.8

Check hardware connection
Some basic checks. Do not say "It has worked yesterday." or "I have not changed anything with the cable." You have to narrow down the reason of your problem.

1. Check, if the cable is plugged in correct: Remove it and add it again at both ends!
   
2. Do you have a second computer, which can be connected by the same cable with the internet? Try it to check, if the cable is ok.
   
3. If there is another cable, working fine with another computer, try it with the computer under Linux Lite.
   

I hope that those answers will at least help other forum members to find a solution for you.
