Expanding your home network
Apple AirPort Express Base Station Wireless Router is a good and inexpensive way to expand your network's reach within your home, especially if you already are using an AirPort Extreme (abbrev. Extreme) primary LAN (local area network) router.
First, locate the AirPort Express (Express) physically where you think it will do the most good--e.g., the other end of the house yet within signal range of your primary router. Any wireless router should be place high up near the ceiling of the room in which it is located in order to obtain the greatest signal range.
Next, plug in the Express and return to your Mac computer, where you will find and open the AirPort Utility app. The app will almost immediately find the Express and ask whether you want to add it as a bridge router to your present network. Answer 'yes' and the connection is made. The Express will repeat synchronously the data signals received from the Extreme and transmitted by users on your LAN.
Adding an AirPort Express will not increase the speed of your network, since it is limited by the speed of data transferred through the Extreme. However, you should find that you have full signal strength available for wireless devices throughout the house now, especially in areas where before signals were weak, intermittent, or non-existent.
The price of an AirPort Express is inexpensive compared to the benefits it offers, and for Mac users, it could not be easier to set up and use. I strongly recommend this approach to extending the range and strength of your LAN.
