Acer Connected by W-Fi, Excellent Signal, my SSID, will not load webpages?

Well I have a small Acer One Netbook XP, just one of 3 computers. The others are handier to use thankfully. I was looking in the Comcast gateway and saw that there were 2 entries for that one Acer. And they seemed to have some small conflicting info. So I thought I'll just delete them from the Gateway and let the wireless router find them and re-assign the Acer again. I didn't touch a thing on the Acer.

No such luck. It's not finding the Acer and giving it an IP. I cannot get the Acer to communicate through the Ethernet cable or the wireless adapter. I have been to device manager and it says it's working properly. The Ethernet shows as if it's connected but will not load a page. The wireless will just not connect with a red X.

I have Googled and tried about everything I can. You name it I've probably tried it. Does anyone know a foolproof way to undo this?

UPDATE: Now apparently it's saying connected after doing a restore. And says the signal is great and I have an IP address. But it is not showing up on the gateway as a connected device and it will not load a webpage?

So to conclude: I have an this netbook that says I'm connected with an Excellent signal to my SSID wirelessly but will not load webpages. I guess I've more or less said that. Any help greatly appreciated.

Thanks, Jack ":-D
