Unable to ping own IP address.

[drew06371]

Hi,

Thanks in advance for any help,

I have a Dell Inspiron 4100 Laptop Service Tag 8S11811 running Win XP Home SP2.
It has an onboard NIC - 3Com 3C920 (according to Device Manager)
The network is made up of a DSL modem, a Netgear MR814v2 wireless router, and a PC that is running fine.

Symptom:
Unable to browse the Internet or Network Neighborhood.

So far,
I can ping 127.0.0.1
I can NOT ping the local address
- It won't return the ping whether the IP is given via DHCP or manually set up
I can ping the router
I can ping an address on the internet
I can ping a name on the internet – www.google.com

So far I have...
Rebooted the laptop and the router
Disabled the windows firewall
Used system restore to go back a few months
Reset the TPC/IP stack with the ‘netsh int ip reset netlog.txt’ command
Deleted the network card in device manager and reinstalled it with the latest driver.
Gone into Internet Options-LAN Settings- and unchecked all the boxes so there’s no proxy.
I’ve tried using the internet setup wizard.
I’ve used MSconfig to disable most then all of the startup programs.
I’ve used netdiag /test:winsock to verify winsock is good

What can I do without reinstalling windows??

you might configure something in the services that stop you in browing the network neighborhood. follow this step.

1. click start
2. select and click run.
3. type "msconfig" and press enter.
4. select the services tab
5. click enable all.
6. click apply and ok restart your computer.

Can you send and recieve emails?

I am sure you have done this but make sure that any third party firewall is turned off.

I am not able to send or recieve emails,
I tried enabling all of the services,
Then I changed all of the services to thier default status.

The only firewall software on the computer is the windows firewall and it is turned off.

Sorry these are simple things but you say that the network is wireless, have you tried connecting wirelessly? Have you tried changing the network cable?

It seems that you have spent a few days on this problem already and not to much advice is helping. From my experience you should bit the bullet and reload windows. In 2 hours time (as long as it isn't the network cable or the network port on the router that is causing the problem) you will be up and running with the problem solved!
Good luck

I have tried swapping cables between the pc and the laptop. Both cables are fine.
I didn't suspect the cable, only because I can ping yahoo with no problem.
I have tried to connect wirelessly and the symptoms are the same as when using the network cable.

I would have normaly reinstalled windows a while ago, but I really wanted to diagnose the actual problem. Also, it's not my laptop and there are a lot of files on it with no way to back them up. There isn't a cd or dvd burner on it.

I think it's a problem either with winsock or the tcp/ip stack, so I was looking for a way to verify those two componets are working correctly.

OK. When you get sick of waiting then you could get a 1GB USB Pen and back up to that. In the meantime can other computers on the network view your laptop and any shared files?

check the protocol that you are using. you should used the client for microsoft network[B] in the network property configuration. If not, try to add it by adding additional client protocol to the netowork property. cheers!

I have run out of time to try to find the cause of the problem, so I went ahead and reinstalled windows. Everything is working fine now.
