Can ping default gateway but cannot access internet

[Guest Anosh]

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!

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 http://www.google.com

ping 74.125.39.104

You should NEVER connect to the internet without a firewall enabled!

 

Are you running IE7 and did you just install the most recent Cumulative

Security Update for IE?

 

What anti-virus application or security suite is installed? What

anti-spyware applications (other than Defender)? What third-party firewall

(if any)?

Re: Can ping default gateway but cannot access internet

 

Thank you all for your replies. The issue has been resolved, it was

some misconfiguration on the DLINK router although I am not sure what

exactly. I have a static IP from my cable provider, and I had set the

router to use a static IP. My ISP suggested changing it to obtain IP

address via DHCP and that seemed to resolve the issue (even though my

static IP settings were identical to the DHCP settings).

 

The reason I had my windows firewall off on the machine is that my

router should act as a firewall so there's no reason to leave the

windows firewall running which in my opinion is more of a hindrance

than help, especially while troubleshooting issues like this.

 

Thanks again!
