Laptop connects to wireless network, but can't "go" online?

Hello. I am running a wireless network in my house, and everything connects just fine, except for my old laptop. My new laptop, my PSP, my Playstation 3, they all connect just fine to the network. My old laptop has had no problems being on the wireless here before, just recently. It says it is connected, but when I try to open my list of nearby wireless networks, it says "Windows cannot configure this wireless connection". Also, no programs can connect to the net, like I.E., Firefox, MSN Messenger, etc.. Nothing will actually go online. Any ideas? I am running Windows XP Pro on the old laptop.
