Internet Connection Problem

[Guest]

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?

Greetings! I figured up your small network, it seems and im
sure that your laptop is connected to your neighbors wireless access
point or wireless router. Try to access the routers setup page using
your laptop wirelessly and check the exact model number on the Setup
page and double-check the model # on your wired Router and you can find
it at the bottom of the router if it matches. The reason why you cant
get online eventhough you have valid ip address-192.168.1.100, it is
because you can have DNS of 172.... perhaps you are using the static IP
from your DSL modem, try to check your TCP-IP settings on you wireless
connection and set it back to Obtain IP and DNS address automatically
and repair the connection.

Thank you.

I could not access anything using the wireless connection. I dis-abled the
wireless connection and the same thing.

When I look at the Linksys Status page here is what it has

(MAC Address: 00-06-25-84-03-1D)
IP Address: 192.168.1.1
Subnet Mask: 255.255.255.0
DHCP server: Enabled


WAN:
(MAC Address: 00-06-25-84-03-1E)
IP Address: 172.16.1.33
Subnet Mask: 255.255.0.0
Default Gateway: 172.16.0.1
DNS: 172.16.0.1
0.0.0.0
0.0.0.0
DHCP Remaining Time: 0:50:49

Could the DNS cache be an issue?
