Okay, so recently(today), wee got a new laptop with Windows Vista on it, and wee have been trying to get it set up our home network.
Right now, all the other computer's connected on the network have XP installed on them. The main computer is a desktop, wired to the router.
Another one is also a wired desktop.
And another one is a wirelessly connected laptop.
Now, wee want to add this Vista one into the mix.
Right now, when you go to Start»Connect to in Vista, it shows our home network, named HOME.
It can connect to the network, but it says it's an "unidentified network" and has limited or no connectivity. It looks like this kind of:

So, I was wondering, how can I connect the computer to our home network?
