2nd Laptop Will Not Connect To Internet Through Router

[JackieP]

Hi I'm having an aggravating problem. I have a D-Link wired EBR-2310 router and 2 laptops: A Dell running on XP, and the other is a Compaq running on Vista. The Dell will connect to the internet just fine, but the Compaq will not. When I try I get a "Page cannot be displayed, server not found" error (or something like that). I tried both Firefox and IE.

When I connect directly through the modem, it's fine. The weird thing is I can log into the router with the Compaq. I've reset the router and power cycled the modem (Comcast) dozens of times, I've even formatted the hard drive.

I don't know what else to do. I'm not a computer expert and don't want to do something that will really screw things up.

Comcast was not much help

As for D-Link, I bought it about 2 years ago so I don't know if I can get tech support.

Is there any more info you need from me?

Any help or suggestions is greatly appreciated.

what are the IP addresses you are getting on these computers when they are both connected?

start > run > "cmd" > ipconfig
