AC1900 Cable Modem Voice RouterPosition Your Modem RouterThe modem router lets you access your network from anywhere within the operating range ofyour WiFi network. However, the operating distance or range of your WiFi connection canvary 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 otherdevices 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 Ethernetcables for wired computers. Place the modem router in an elevated location, minimizing the number walls and ceilingsbetween 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-Base of a cordless phone-2.4 GHz cordless phonePlace the modem router away from large metal surfaces, large glass surfaces, insulatedwalls, and items such as these:-Solid metal doors-Aluminum studs-Fish tanks-Mirrors-Brick-ConcreteWhen you use multiple access points, it is better if adjacent access points use different radiofrequency channels to reduce interference. The recommended channel spacing betweenadjacent access points is five channels (for example, use Channels 1 and 6, or 6 and 11).Hardware Overview13
