valid ip adress no internet connection

Specs: Windows XP
Hi i just recently got at&t internet set up at my house and have a modem which i can access the internet on from my laptop and desk top computer. Yesterday the internet on my desktop, which is an older dell working on windows xp, was working fine and then after turning the computer off and turning it back on the internet just stopped working. It shows that I am connected to the internet through my modem still but ie just says ie cannot display the page. Im aware that it might be a firewall problem so I just went and uninstalled any anti virus that was installed on the computer and still nothing...I called at&t and went through steps with them to no avail They said I had a valid ip address and we reset all ie settings but still nothing. I can access the interenet from my laptop just fine so I dont know what to do! please help!

Go to a command prompt and type ipconfig /all and post the results.

If you are a using a router, which with two computers you probably are, all you ISP can telll you is if your router is getting a valid IP address. The ISP cannot tell is the router is passing a valid IP address onto your computer. ipconfig /all will tell you.

Im aware that it might be a firewall problem so I just went and uninstalled any anti virus

So why did you uninstall your Anti Virus. An Anti Virus is not a fire wall and will not block a network connection in the same way as a firewall can. Reinstall your anti virus, it is unlikely to be the problem

Is your Network adapter disabled?? Look in Device Manager for any item that may have an icon next to it showing that item to be disabled.

EDIT: StuartS beat me to it.

Okay I did that and it says
Ethernet adapter wireless network conection 2:
ip address.....
subnet mask....
default gateway....

and when I ping a website it just saysping requesst could not find host.

I uninstalled it bc the tech at at&t said it could be my firewall on my anti virus and the firewall on the modem could be blocking eachother or something like that but now i cant reinstall it bc i cant get onto the internet

I think the tech is clutching at straws. A firewall wont stop you pinging other computers but it will stop other computers from pinging you.

The ipconfig numbers look fine.

Log onto the routers management interface via the default gateway at 192.168.254 and check that you are actually connected. You can see there is you are getting an IP address from your ISP. There is usually a diagnostic screen that will tell you if there is a problem
