Position Your Modem Router

The modem router lets you access your network anywhere within the operating range of your

wireless network. However, the operating distance or range of your wireless connection can

vary significantly depending on the physical placement of your modem router. For example,

the thickness and number of walls the wireless signal passes through can limit the range.

Additionally, other wireless access points in and around your home might affect your modem

router’s signal. Wireless access points are modem routers, repeaters, WiFi range extenders,

or any other device that emits a wireless signal for network access.



To position your modem router:

1.

Place your modem router near the center of the area where your computers and other

devices operate, and within line of sight to your wireless devices.

2.

Make sure that the modem router is within reach of an AC power outlet and near Ethernet

cables for wired computers.

3.

Place the modem router in an elevated location, minimizing the number walls and ceilings

between the modem router and your other devices.

4.

Place the modem router away from electrical devices such as these:

•

Ceiling fans

MAC address

WiFi network name (SSID)

Serial number

Password (key)
