5. Operating Modes
The NEWFAST NF-RE516 typically operates in Repeater Mode, extending the range of your existing Wi-Fi network. It can also function as an Access Point (AP) if connected to your router via an Ethernet cable, creating a new Wi-Fi hotspot.
5.1 Repeater Mode
In Repeater Mode, the extender wirelessly connects to your router and amplifies its signal, extending coverage to areas with weak or no Wi-Fi. This is the default and most common operating mode.
5.2 Access Point (AP) Mode
To use AP Mode, connect the extender to your router using an Ethernet cable. The extender will then create a new wireless network, converting your wired connection into a Wi-Fi hotspot.
