I am currently using a wireless setup with a The D-Link Xtreme N Gigabit Router (DIR-655).
D-Link DIR-655 Xtreme N Gigabit Router
It was a little pricey but I have no problems whatsoever using this router for everything from PS3, laptops, to Ipod Itouch's. Definitely needed to protect the wi-fi due to the strong output. I would recommend this to anybody that wants to go the wireless route.
