No problem, I now suggest you do the following:
-
Run the command “
sudo pppoeconf
” again and see if you made a mistake when entering your username and password. -
Start the live CD and run the command “
sudo pppoeconf
” in live mode and see if it connects, if it does; you know that there is a problem with the installed system, I would recommend at this point to do a fresh install and run the command once more if necessary after the installation process has finished. Only do a fresh install with an active internet connection!.
