Any help of step in the right direction would be much appreciated

Did you power cycle the CM after you cleared the MAC address and selected "Obtain an IP address automatically"? You need to. Some people also suggest power cycling the router as well so they are both off together. It should not be necessary but it won't harm. (If you plug the CM back directly to the PC, you will need to power cycle the CM again).

Yes I did power down the Modem and the router, but made no difference!!

Something seems very wrong here, but I can't put my finger on it. Can you post a screen dump of your set up?

Have you disabled WAN1 and/or set any load balance properties?

yes I have disabled LAN 1 and all load balancing properties, also disabled the firewall to pass everything!! As I am setting this up for my brother in-law I have taken the router and linked this on my LAN, I shall send you the screen dump!!! of the current configuration

how can I send you a screen dump!!!
