Lan works OK internet fails

Specs: Windows XP
Using a Belkin N wireless router I can establish a working LAN between 2 desktop PC's both connected to the router via ethernet and a laptop connected via wireless. All PC's can access shared folders and access the internet.

Because of poor wireless reception at end of house I wish sometimes to connect the laptop using ethernet and 'HomePlugs'. But to set things up I am connecting the laptop to the router with a long ethernet cable. When I do this I have been able to establish a working LAN connection but can not manage to get an internet connection.

I see a WAN Internet connection listed on the two desktops and on the laptop when connected by wireless but NOT on the laptop when connected via ethernet. I guess this is the problem but how do I set up a WAN for this ethernet connection?

The WAN connection is done by the router which is working. Anything after that is done by NAT. When you connect the laptop by Cat5, disable the wireless NIC. If you still don't have internet, run from a command prompt,
ipconfig /all and post the results.

Thanks for your prompt reply. I don't quite understand the reference to 'wireless NIC'.
Is this anything to do with the function key that disables wireless capability?
Will experiment in the maorning.

Yes, it does. You only want one interface enabled at a time. Use the function key to shut the wireless adapter (NIC), when you connect using the cat5 cable .

I tried shutting the wireless adaptor without success but traced the problem to an inaccurate Default Gateway address. Thank you for your interest in my problem.
