Internet Connection Problem

[otter]

I have 2 machines, laptop and desktop, connected to the wired router. I can access the internet from the desktop. I can not from the lap top. This includes from a IE browser, Outlook and IM. I can get to the router log in page from the laptop so it seems the lap to is talking to the router. The laptop also recognizes when the network cable is unplugged or plugged in. Laptop also has a wireless network card. We do not have a wireless router.

The settings on the laptop have not been changed. I have tried different cables, powering off the router.

The router is connected to a DSL modem using SBC DSL.

IP address is 192.168.1.100
Default gateway is 192.168.1.1
DHCP server is 192.168.1.1
Sub net is 255.255.255.0

My DNS server is 172.16.0.1.
I can access the Linksys router configuration page with a browser
I can not get to the internet using a browser
I can not ping www.google.com etc.
I can ping the Default gateway is 192.168.1.1

When I change the DNS server to 192.168.1.1
I can access the Linksys router configuration page with a browser
I can not get to the internet using a browser
I can ping www.google.com etc.

I downloaded winsockfix and lspfix and they did not work.
I ran reset and rebuilt ip stack, did not help

Other laptops work on same cables, etc.

Any other ideas or things to try?

DNS server address provided by your isp might have to be put in to the router
it should have a place for primary and secondary dns server addresses
get hold of your isp documentation and see if they are required it or not
you may have the numbers wrong for sure 192.168.1.1 is wrong for a dns server that is a private address


this is all i could find on the dns server you have listed
