What wireless router is best to work with streaming games and video?

I want to get my Wii wireless capability working on my TV. Want to set up a wireless router that is robust enough to handle online games and possibly video. I have a budget of about $250 and want the best bang for the buck I can find. Thanks in advance for your suggestions.|||check out the Cisco 610N. Good signal strength, with dual channel. A little more complicated to set up than some, but worth the extra effort.
