Position Your Modem Router
The modem router lets you access your network anywhere within the operat\
ing 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 rou\
ter. 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 rang\
e extenders, 
and any other device that emits a wireless signal for network access.
Position your modem router according to the following guidelines:
• 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.
• 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 wa\
lls and ceilings 
between the modem router and your other devices.
