Are N Routers for wireless use only?
Wifi N and Wifi G are the two main wireless networking standards
commonly used today. So when making you decision WIFI N vs. G, the
ideal solution to this is to get a dual band router that can deal
with both the 2.4 GHz band and the 5GHz (Wifi N) band
simultaneously. Wifi N can operate on 2.4 GHz but will only operate
at the speed of the lowest device on the network.
