Wired network and Knoppix 6.7.0 and 6.7.1 not working on Dell Latitude D520 laptop

[elie]

Hello,

I am trying out the Knoppix 6.7.1 on the dell latitude laptop but no internet connection through the wired built-in Ethernet. Knoppix 6.7.0 has the same problem. I can connect fine with other Live CD boots such as Knoppix 5.1.0, Debian xfce latest, wary puppy 5. I am new to Linux and I am not sure were to start. I would like to be able to use Knoppix if I can get the wired network issue ironed out. Thanks.
