Hi,

I'm stumped by a networking issue I'm hoping someone can help with. I
have a Windows XP Pro (SP2) computer connected to the internet via a D-
Link 524 Wireless router and a cable modem connection. I also have a
VoIP phone adaptor connected to the same router.

Here's the problem. For some reason the VoIP phone adaptor connects to
the internet just fine, however the computer does not.

The router's address is 192.168.0.1
The computer gets an IP of 192.168.0.100 (assigned by DHCP).

I have verified that the computer's default gateway is set to
192.168.0.1. If I ping yahoo.com, it resolves the correct address
206.190.60.37 but is unable to ping yahoo.com and says Request timed
out.

I tried doing a tracert yahoo.com and it gets to:
Tracing route to yahoo.com [206.190.60.37]
over a maximum of 30 hops:

1 <1 ms <1 ms <1 ms 192.168.0.1

And fails from then onwards.

Surprisingly enough the VoIP device works fine and I am able to make
and receive calls.

I have tried changing the computer's IP address statically to
192.168.0.200. It made no difference.
I've considered the possibility of the VoIP device having its own DHCP
server running that interferes with the DLINK router and changed the
DLINK router to use the 192.168.10.1 subnet. It assigned the PC an IP
of 192.168.10.100 but the issue still persists. The VoIP router
continues to work without any issues.

The Windows Firewall is turned off on the XP machine and the service
is disabled. I have tried reseting winsock by using the command line:
netsh winsock reset and restarted the computer. This has not helped
either.

What would cause the machine to see the default gateway but not the
internet? Would appreciate your advice.

Thanks!
Anosh

A good starting point would be to post the output you get from
this command:
ipconfig /all

You should also report what happens when you ping some site
other than Yahoo, e.g. Google, both by name and by IP address:
ping www.google.com
ping 74.125.39.104
