Default gateway ping returns error

July 22, 2010 at 04:05:27
Specs: Windows XP SP2, Intel Core 2 Duo 3.00GhZ processor/ 2 GB RAM
I use broadband through LAN cable directly plugged in to my ethernet port through a USB to LAN connector. While trying to connect to internet through a client software provided by my ISP, I'm getting a message "Couldn't contact server". I pinged using my IP address, default gateway and DNS server address, IP address ping returns a reply, while, Default Gateway ping and DNS Server ping returns "Request timed out" error.

Service provider personnel told me that it could be due to IP conflict, since, being an amateur, I didn't know about networking a lot and initially I configured my internet connection by inserting the USB to LAN connector in all of the 4 USB slots in my laptop till I came to know that it creates a conflict.

Now, I have re-inserted the USB to LAN connector in all the USB slots in my laptop and manually uninstalled the USB 2 LAN driver. I also erased the IP addresses from all the USB slots except one, from which I'm trying to connect to the internet.

To my little knowledge, it should solve the conflict issue and I should be able to connect to the internet now.

But I'm getting the "Couldn't contact server" error now also.

One more thing. When I'm trying to right click on the Local Area Network icon at the bottom right most corner of my monitor and clicking REPAIR, it's saying "Windows could not finish repairing the problem because the following operation could not be completed:
Clearing the ARP cache
For assistance, contact the person who manages your network."

I'm at loss. Can anyone tell me what should I do to get working on internet?

My system specs:

INTEL Core 2 Duo processor 3.00 GHZ
2.00 GB RAM
DELL INSPIRON 1525 laptop

You shouldn't need software from your ISP. The driver for the adapter should be sufficient. I use a USB to Cat5 adapter on one of my machines & all works well.

All machines should be connected to the LAN ports on the router or a switch before the router.

For all you write djsinha you never mention what you are plugging into for internet access. Modem? Router?

If there was a ip conflict it would have been clearly evident to you from the splash screen message saying ip conflict. I see no mention of you seeing this.

This being the case the tech was guessing.

I would be more inclined to believe that you are putting in an invalid static ip when you should be set for dhcp [auto assigned] or you physically are not connected to the router [bad interface/cable/usb converter]

Did you confirm the ip settings with the ISP?

@ Guapo: The software is just a client interface module. I can do without it also. And I dont' use a router. A laptop and the lan cable plugged into the ethernet port. Thats it!!!

Now, since the ethernet port on my laptop stopped functioning, I use a simple USB to LAN connector. No router, no modem. A laptop and the lan cable only. Simple...

@ Wanderer: I use a laptop and lan cable. As simple as that. No router. No modem.
And, I was getting an IP conflict message, which I resolved succesfully. Auto assigned DHCP doesn't work. I use the IP address given to me by my ISP. And I have double checked the IP address, Default gateway and DNS Server address - all the addresses are correctly set in by me.

I am totally lost. If there is no router & no modem, where does the other end of the cat5 go & how can there possibly be an IP conflict without a router?

It's because djsinha is on a lan and doesn't understand what is beyond the wall socket he plugs into.

"which I resolved succesfully"

Guess there is no need for our assistance now.
