I got a new laptop, and after I plugged in my network cable, I couldn't connect to the internet. what do I need to do? I'm attached to a router, and the other computers work fine. One strange thing is the router assigns the laptop an address of *.*.*.105, where the other computers have like 2, 3, 4. What do I need to do? I've already run the network setup wizard, and that didn't change anything.
