Position Your Modem Router
The modem router lets you access your network from anywhere within the operating range of
your WiFi network. However, the operating distance or range of your WiFi connection can
vary significantly depending on the physical placement of your modem router. For example,
the thickness and number of walls the WiFi signal passes through can limit the range.
For best results, place your modem router according to the following guidelines:
•
Place your modem router on an upper floor of a multifloor home or office.
•
Place your modem router near the center of the area where your computers and other
devices operate, and within line of sight to your WiFi devices.
•
Make sure that the modem router is within reach of an AC power outlet and near Ethernet
cables for wired computers.
•
Place the modem router in an elevated location, minimizing the number walls and ceilings
between the modem router and your other devices.
•
Place the modem router away from electrical devices such as these:
-
Ceiling fans
-
Home security systems
-
Microwaves
-
Computers
-
Baby monitors
-
Base of a cordless phone

Place the modem router away from large metal surfaces, large glass surfaces, insulated
walls, and items such as these:
-
Solid metal doors
-
Aluminum studs
-
Fish tanks
-
Mirrors
-
Brick
-
Concrete
When you use multiple access points, it is better if adjacent access points use different radio
frequency channels to reduce interference. The recommended channel spacing between
adjacent access points is five channels (for example, use Channels 1 and 6, or 6 and 11).
Install and Activate Your Cable Modem
The most common way to cable your modem router is the simplest, without any other routers
or gateways on the same network. You can also cable the modem router to another router or
gateway and log in to the modem router to specify this setting.
Cable the Modem Router
The modem router comes configured to work as both a modem and a router. You can share
your Internet connection without connecting the modem router to a router or gateway.
