Dell :: Cg814wg V2 - New Laptop Says It Is Connected To Wireless Network But It Isn't

My wife just bought a new Dell Intel Centrino. I can't seem to get it to connect properly to the wireless router/modem. It is a Netgear cg814wg v2.  The wireless status shows that the computer is connected to the internet. But yet the only thing I can seem to do is searches on Google. Any other site that I try to visit does not open. If I plug the laptop into the modem directly with a Ethernet cable it works flawlessly. So it seems that the laptop can communicate with other computers on the network, but I just don't have any internet. Or very limited internet. And I've tried this in both IE and Google Chrome. 

I'm not a computer/wireless network genius, but I've spent hours trying to troubleshoot this issue with no success. I've reset the modem. Unplugged the modem. Typed config/all and all the other ones I found suggested online in the command prompt. Checked the settings on the modem itself and on the laptop. I Still can't seem to get it to work. I have 3 other computers in my house that all work just fine wireless. They are all older computers with XP on them.  I also found out that the wireless adapter in the laptop is a N 1030 adapter. But I don't know if that is compatible with my modem or not. 

Well I became convinced that the problem was with the Netgear itself and I needed a newer model. I contacted Comcast whom supplies the modem for me and told them my situation. She basically told me that I needed to contact Dell Technical Support to see if the laptop was set up or equipped with what it needed to be used with my Netgear setup. Well, she said something that sounded a lot better than that.
