Your Netgear AC1200 setup wireless range extender on a wireless repeater or Extender Mode can be done by connecting with a non-Netgear router to your Nighthawk router. It helps to expand your WIFI coverage. Netgear Nighthawk extender repeats your existing WIFI signal instead of broadcasting a new one. After boosting your existing network range, the Netgear Nighthawk extender speeds up your WIFI up to 1900 Mbps and 700 mW with high-powered amplifiers.
