Make sure you set the IP Address and DNS servers to DHCP (automatic)

Is the new computer getting an IP address? what is it?

If not, make sure the router is giving out enough ip addresses, you need to go into the router setup to be sure.

Or you can give it a static IP address, like 192.168.1.99 (or any number below 99, but not 1 because its taken by the router)

But then you will have to put in the DNS servers too, I think they are like 65.32.2.130 and 65.32.2.136

Make sure your gateway is set to 192.168.1.1

Hope that helps
