Cannot find wireless network

Hi

I purchased a MacBook Pro today. I have an iMac. I connect to the Internet via a NetGear wireless router. My son has an xBox that also connects to the Internet this way.

However, I cannot find the network when I started setting up my MacBook. I rescanned several times and couldn't find it. There were other networks from the neighborhood but not mine.

I tried going into Other Networks. I checked the name of the network on my son's xBox and I checked the name and password via Key Chain Access. I was also able to get the password from Key Chain. I tried both network names as well as the password but it wouldn't work. I tried again when Network Configuration asked me if I wanted to access a closed network but no dice.

What am I doing wrong?

Oops, Mods, I apologize. I meant to put this in the MacBook Pro section. Sorry. Please move.
