Can't connect to internet

[KoolAidMan]

I recently had to get a new motherboard for my PC. It was working fine online with the old one before it broke, but when I put my new board in the internet at my house wouldn't work. I figured it was something I had to setup so I took the PC to school without much thought. The school network worked immediatly when I connected. Now I am home for break and I can't connect to the internet here. This computer downstairs works, but my computer connected to this connection does not. I called my internet service provider but they couldn't find anything wrong. They mentioned that it seems like something is wrong with the ethernet card and the IP address, but the few things we tried in command prompt didn't do anything.

My computer recognizes that it is in fact connected, when I connect the wire it says it's a good connection, and tells me when I disconnect it, so it doesn't seem like the connection is the problem. I tried using the repair runction in the network options, but it told me that it could not setup the IP address.

Anyone have any ideas on what to do about this? I am pretty much lost when it comes to this sort of thing.

i assume you are connected to a broadband router. go into command prompt (start > run > cmd) and type in ipconfig/all. make sure that your computer has an ip address and all spaces are filled out (default gateway, dns, subnet, etc). if everything is filled in, your computer should be able to connect to the internet, since other computers in your network are able to.

Do an ipconfig /all on the machine that is working ok and your one and post the results

In General, you can debug the Network Settings of a computer by following these steps.

Step One. Check the Network parameters in the Computer's Device Manager. Make sure that the Network Card drivers are installed correctly; i.e. there is No IRQ conflict, and No Ghost installation. http://www.ezlan.net/faq#ghost

Step Two. Verify Basic network setting in the OS: http://www.ezlan.net/Installing#verify If the above two Steps indicates that every thing looks good but functionally it does not work.

Step Three. Check (and repair if necessary) the Socket Layers, Winsock, and or refresh the TCP/IP Stack. http://www.ezlan.net/clean#refreshnet

If need to Reinstall; Log to this page it have a lot of links to instructions for Windows Network Installation -http://www.ezlan.net/Installing.html

I did ipconfig /all on the good computer here, and it has everything filled in, but it says something about 'IP Routing Enabled...No.' Doing the ipconfig on the one that doesn't work comes up with a whole lot of wierd things like ffe$ type stuff, big long strings of that where IP address should be. Is there maybe a modem setting I need to change? I didn't know, but apparently my parents got a new modem while I was at school. Also, it's a cable internet connection with a Linksys router. The working computer is also running through the router.

Try running the latest version of the Winsockfix ... see if that helps ... if not, reinstall the Windows TCP/IP stack
