BleepingComputer.com: Laptop can't connect to the internet, but can connect to router

My laptop has Windows XP, and now can't connect to the internet through the ethernet cable through the router. The wireless works just fine. It can connect to the router, but that's it. My other computers on the network (all of which have Windows XP as well) connect just fine, so it's something having to do with the settings on the laptop, I think.

The diagnostic tool through IE6 gave this:

Problem solved!
Since I can't delete this topic, I'll just post my solution.
I went to Network Connections > Local Area Connection > Properties > Internet Protocol (TCP/IP) > Properties and clicked both options to obtain automatically. I had forgotten that I changed these settings for a game.
