The label on the bottom panel of the modem router shows the preset login information, MAC 
address, and serial number.

The modem router lets you access your network from virtually 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. For best results, place your modem router: 

Near the center of the area where your computers and other devices operate and 
preferably within line of sight to your wireless devices.

So it is accessible to an AC power outlet and near Ethernet cables for wired computers.

In an elevated location such as a high shelf, keeping the number of walls and ceilings 
between the modem router and your other devices to a minimum.

Away from electrical devices that are potential sources of interference, such as ceiling 

fans, home security systems, microwaves, computers, or a 2.4 GHz cordless phone and 
its base. 

Away from any large metal surfaces, such as a solid metal door or aluminum studs. Large 

expanses of other materials such as glass, insulated walls, fish tanks, mirrors, brick, and 
concrete can also affect your wireless signal.
