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 (192.168.1.1), 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
Why am I able to connect to the Internet through Windows, but not Ubuntu? How can I resolve this?
