Please be gentle - I'm a complete technical numpty.

Got myself a nice shiney new laptop so that I could move around the house and still have intenet access. I'd tried a wireless network for 2 PC's some time ago and gave up!
You can imagine my delight when a friend loaned me two power plugs and explained how easy they were to set up. I was even more delighted when I plugged everything in and it actually worked. So far so good. Delight turned to dismay when I tried to power everything up the following day only to find I had no internet connection on the laptop. I have rebooted, switched cables, to no avail. The router is showing an amber light on the port which is connected to the PC - the PC still has internet access. It used to have a green light on the port connected to the powerplug, but somewhere along the line I've lost that.

Tried Belkin customer support - I really don't think the bloke had a clue what I was on about. He suggested it was the network card in the PC that might be faulty, however I switched to an old PC that has a relatively new network card in it and the problem is the same.

Any ideas? This is more frustating than if it had never worked at all.
TIA
