 N600 Wireless Dual Band Router WNDR3400v3
•Away from electrical devices that are potential sources of interference, such as ceiling 
fans, home security systems, microwaves, computers, or the base of a cordless phone or 
2.4 GHz or 5 GHz 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.
When you use multiple access points, it is better if adjacent access points use different radio 
frequency channels to reduce interference. The recommended channel spacing between 
adjacent access points is 5 channels (for example, use Channels 1 and 6, or 6 and 11).
Prepare the Router
To ensure proper heat dissipation and for router stability, it is important that you connect the 
stand and place your router in an upright position.
To prepare your router for installation:
1.  Carefully peel off the protective film covering the top and sides of your router.
