That's the one, but if you're going to be doing any large file transfers, you might want to think about an 802.11n router. The current best example of this is the Airport Extreme Base Station, at least according to a couple of comparison articles about a year ago on arstechnica.

The only downside to the Airport is that it has to restart every time you make a config change. Which is silly.
