Theoretically, 802.11 g is good for up to 300ft, but that all gos out the window when you throw in walls and what not. 802.11 n is faster and supposedly more resistant to interference. So if you are doing a lot of work over wireless within your network, N is the way to go. But you probably will not see any difference in internet connectivity. You can pick up a quality N adapter for less than a some G models so I would look around. If you just need a WAP to get to the internet stick with G and save some cash on not having to get adapters.
