Hello friends, Taringueros!
Good to start, in this post I will explain how to solve a very common problem that occurs in Windows 7 (Especially in Notebooks that are connected to a network by Wi-Fi, when you want to connect by broadband, the PC to the network jumps this error, for example my case), which is an error that occurs when we try to connect to the Internet through a broadband modem. They say that the error is because in this windows, the Raspppoe.sys file. Well I personally had this problem and in my case this file did not produce the problem, I could solve it in a very simple way.
The problem apparently on my computer was that windows had disabled the local area connection.
