Angry Solved: XP laptop cannot connect to the Lan internet
Story: Alright so I recently brought my laptop with me to Florida. We have lan setup here. However I cannot connect to the internet whatsoever. My laptop does say it's connected however it just won't connect. Now the wierd thing is that my sister's laptop will connect to the internet with the SAME ethernet cord and the SAME ethernet jack that I used to try and connect mine.

Side Information:
OS: XP
Ibm thinkpad laptop

I recently uninstalled my avg antivirus software thinking that might be the problem
I also decided to turn off my firewall
Both didn't work

Thanks in advance for any help

Click Start, Run and in the box, type: cmd then <Enter>.
In the block command box that should open, type: ipconfig /all then <Enter>
Other than the IP address, verify that the rest of the numbers are the same between yours and your sister's laptops. You should have the same Default Gateway, DHCP and DNS servers, etc.
Let us know if things are substantially different.

Yeah things are substantially different. First of all my computer doesnt even list any of those things that you said. However my sister's computer lists them all. I can't even find the things your talking about on my computer. Would you like a screenshot of both screens to see what im talking about? Or would I be giving out important personal info?

If you right-click on My Computer and click on Properties, then on the Hardware tab, then on Device Manager, do you see any yellow "!"s or red "x"s? Is there a Network Adapters entry? Anything in it?

If you double-click on the Intel network connection, does it say "This device is working properly"?
Did you power up with the laptop plugged in or under battery power?

Yes it says this device is working properly. And to answer your other question I have tried the laptop both plugged and unplugged.

A wireless network adapter doesn't have anything to do with a wired connection. Is there no wired adapter listed in Device Manager?

When you did the ipconfig, did anything indicate that a cable was unplugged?
Try ipconfig /renew and see what happens.

I take it there is no wireless network available. Did this laptop work previously?
Did you inadvertently disable the NIC in BIOS setup?
You may need to try to download the NIC drivers using the other laptop and transfer them to yours, perhaps with a Flash drive.

Oh yeah one more thing. You know those two computer icons that light up at the bottom of your screen when you plug the ethernet cable in. Well in my computer, only one of those computer's light up where as on my sister's both of them light up. I dont know if that helps but just providing some more info.

I never did play with my laptop's BIOS settings. But I could prolly transfer the drivers on my sisters comp over to mine. I just don't know how. Would it still work if they are different computers? Ill take a look at her device manager and see what I can find.

If there's no wired network adapter listed in Device Manager and there are no unknown devices listed, then the adapter is probably shot. You'd have to buy and install a replacement.

A completely different computer's drivers won't help, and the problem isn't driver-related if there's nothing at all listed in Device Manager.
