Take the 2-minute tour ×  I have a dual boot on my PC. I can
access Internet through Windows but cannot do it through Ubuntu.
I was able to connect to Internet on both OSses until some days
ago, when my brother reset my router (or modem, I don't know) to
factory settings and the Internet stopped working on both OSses.
After some tweaking the setting in the DSL setting page in
Windows (, it started working properly without having to connect
manually through the network dialog.  But it still isn't working
on Ubuntu 12.04. Additionally, I can't open the settings page
from Ubuntu but in Windows it opens up perfectly.  In Ubuntu, I
tried doing sudo pppoeconf, but it said that it cannot detect
access concentrator on eth0.  Why am I able to connect to the
Internet through Windows, but not Ubuntu? How can I resolve
this?  share|improve this question Try changing your default
