Router Label
View the label on the bottom of the N750 wireless gigabit router to identify the security PIN, serial 
number, port connectors, status lights, and default login information.
Positioning Your Wireless Router
The N750 wireless gigabit 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 router. For 
example, the thickness and number of walls the wireless signal must pass through may limit the 
range. For best results, place your router: 
• Near the center of the area where your computers and other devices will operate, preferably 
within line of sight to your wireless devices.
• 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 N750 wireless gigabit router and your other devices to a minimum.
• Away from electrical devices which are potential sources of interference, such as ceiling fans, 
home security systems, microwaves, or the base for a cordless phone. 
• 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.

Failure to follow these guidelines can result in significant performance degradation 
or an inability to wirelessly connect to the Internet.
