I recently bought this router and 2 D-Link DWL-520+ cards. The router is in the basement of my house. It is connected by ethernet to a computer with dialup internet. I am trying to share files and the internet with this. I have the 2 other computers upstairs with the wireless cards. The computers are side by side. But I can only get a good signal in one of them. The other doesn't pick the signal worth a ****. Is there a way to get this to work? And how would I share the internet? All computers are running Windows XP Pro.
