Vauge Error Connecting to Internet

Question

I bought my macbook pro yesterday and am a little on edge since I'm already having problems with it. I bought the macbook pro yesterday afternoon. I came home and immedietly booted it up. It ran through the first time boot stuff just fine, even when it got to the internet connections part, airport quickly connected to my home network without a single problem. I played around with it for a few hours, doing NOTHING that would affect any network connection settings. I plug it in to charge and go out to dinner. When I get home, it is disconnected from the internet, and cannot connect. I simple try to reconnect, but it vaugely says that there is an error connecting to network "home". After this I run network diagnostics tools over and over, still it no avail. It says I need a password to access the network, and I know for a FACT that my network does not have a password, let alone any other security features. All my pc's, which are connected to the network wirelessly, work just fine. It is impossible that another network is interfereing because I live on a twenty acre farm, hince the no need for network security. See basically, my network is operating as it always does, so I know the router is not the problem. Since I know virtually nothing about macs, I figured I would post here and hopefully someone could give me a solution.

i certainly hope this isn't the case but you should check out these topics if you haven't seen them yet. you may be experiencing what others are also having trouble with. there are a lot of MacBooks and MacBookPros having connection problems these days. and also a lot that are not, just to be fair.
