Thanks very much for your help. This is now a SuSE posting! No windows were opened in the making of this post!
I found a SuSE.com page entitled 'Setting up an Internet connection via Cable Modem' and although I couldn't follow those intructions either (I'm trying, honest I am) I knocked out the eth0 card and it then kinda reconfigured using the eth1 and suddenly I was on!!!
I'm so chuffed, plus I'm impressed by the speed you guys came up with advice. Well done.
