Networks A most complex and interesting problem

My dad has an old P3 HP laptop with an integrated 10/100 ethernet and a Motorola wireless 54 card. I have a network consisting of a Linksys router with several PCs on it and a Motorola wireless AP/router combo set up as a separate subnet. Connected to the Motorola is an Xbox and a PC. All of these can access the internet.

The laptop fires up. I plug it in with a piece of cat5 to the Linksys, and wirelessly to the motorola. Both cards have an IP address. I can access any computer on my network, but I can't access the internet. I figure it might just be an IE problem, so I try to ping google. Nothing. Well, maybe it's a DNS problem. I find the IP for google and ping that IP. Nothing.

Any ideas? This one really stumped me. Too bad my Net+ was more about memorizing acronyms than troubleshooting problems...

 

which router are you using to access the internet, the motorola or the Linksys?

 

Linksys

 

Make sure your Internet settings are referring to the linksys router then, perhaps that's causing a problem.

 

and if you don't wirelessly connect to the Motorola? does it work then?
