The NETGEAR 3700, or NETGEAR WNDR3700, operates on both the 2.4GHz and 5.0GHz frequencies, enabling the router to output a strong signal strength to computers and other network-capable devices in the area. Other devices close by, however, like cellphones and microwaves, can interfere with the signal strength if the router functions on the same channel. Changing the channel on which the router broadcasts its signal can boost the signal strength of the NETGEAR 3700. Confirming that the NETGEAR WNDR3700 is functioning in the correct mode will also ensure that the router outputs the best signal possible.
