I am just surprise about this problem ! my internet connnection is boardband connection in which my isp "worldlink" has given me a device which had kept in the terrece and the wire from tht device is connected to the addapter and from which it is connected to my pc . And the problem is that the internet works fine in windows and ubuntu bt it doesnt works in backtrack . To solve it i went to worldlink office . There nobody knows how to use linux so i try myself by typing "pppoeconf" in terminal n i was surprised that it get the connection n works fine bt when i come home n try the same thing it doesn't works??
