lost ip address

Specs: Windows XP
I rebooted my hp windows xp computer and am now unable to connect to the internet. I get an error saying the ip addess is invalid. When I do ipconfig, no information comes up. I have tried several different commands, etc. and still get nowhere. I spent two hours on the phone with my isp tech support and they are telling me it's a computer problem, not theirs. My other Dell xp computer is on the same dsl modem and is doing just fine.

Try uninstalling your network adaptor by going to the device manager, highlight the name of the ethernet and uninstal. Reboot and windows will detect the new hardware, make sure you have fresh driver for it. good luck

How are you connected to the inetrenet (DSL, CABLE, DIAL-IN)

DIAL and Sometimes CABLE (if your router is in Bridge Mode) the Public (iNTERNET) IP address is given to your NIC (network Interface Card) of your computer.

With DSL the Public IP Address is at the outside of your Modem. Your Modem will NAT the address (translate) to the inside with a Private IP Address. THe modem wil give an IP Address in the same range to your NIC on the computer.

If their isn't one the following could be the problem

1. No cable attached or cable is defect
Check if lights are flashing on modem and PC nic

2. Your NIC in the PC is Disabled
Check at Network Connections

3. NO IP address is given to your NIC (PC)

Open dosbox and type: ipconfig / renew

check with ipconfig /all
