wireless internet connection problem?

I just got a Netgear router from staples (one they highly recommended). I set it up and for the most part it is working okay. We have a laptop and a PS3 in the house. My boyfriend's connection on the PS3 is not that great, he plays call of duty mw2, and the connection has been lagging and it shows his connection is only one bar. My laptop gets the connection fine and I am having no issues. How can I make it so he gets a better connection? All the settings on the PS3 are fine, and the NAT type is open.
