The AC750 mywifiext Netgear wifi range extender is the EX3700 model with excellent connectivity throughout your home or office. It has two external antennas to give better signal in all the areas, taking away all the dead zones. The wifi range extender works like a bridge or a gateway between the router and the wifi enabled devices that are not in the wifi signal zone. The range extender takes the wifi signal of the router and retransmits it with its own network to each and every nook and corner.
