I have come to this place because i cant get my pppoe on ubuntu 12.10 to work an am pretty new to this so please bear with me.

with sudo pppoeconf i get the following message:

"Sorry I scanned 1 interface, but the Access Concentrator of your provider did not respond.Please check your network and modem cables.Another reason for the scan failure may also be another running pppoe process which controls the modem."

Unnecessary to say it is connected via cable.I have found another similiar case in this forum, but my connection neither did work with windows i had earlier with this computer.There I though it was a problem with the "raspppoe" driver but that might have been wrong in retrospect.
