Just be aware that for any N-class router that is set to accept connections from either G- or B-class devices as well as N-class, that once a slower device connects the speed for ALL devices gets lowered to that level.

For example, say that two N-class devices are connected to an N-class router. They will both enjoy N-class speeds. Later a G-class device (like the N900) connects to the same router, all three devices now are "dragged down" to the G speed as long as the G device is connected. As soon as the G device disconnects the connection speed will increase back up to N-class.

This is a hardware limitation of all routers. Some have dual-channel capability, so they can service two classes of devices at the same time without affecting the higher speed devices, but they're a lot more expensive.
