A wireless N router is a router that supports the new 802.11n wireless standard. The N standard is superior to most other existing wireless standards because it uses multiple frequencies in order to create several data channels that allow faster download speeds. The standard also calls for the ability for a wireless N router to be able to combine strong and weak signals in order to create a consistent signal where there might not have been one previously. Even though a wireless N router supports all of this functionality, the receiver used on a laptop or device must also support the N standard in order to work properly.
