Hi McG

If I understood your description I had a very similar configuration to you.

I had similar promblems...after much checking, testing and trialling I solved the problem by unhooking my desktop from the wired connection and plugging it into the Belkin wireless one.

Since then I have had no problems and have recently added another laptop to the network which still works like a dream.

My ISP is BT.

Cheers
