Use The Extenders In Access Point Mode - NETGEAR EX3920 Quick Start Manual

Use the Extenders in Access Point Mode

You can use the extenders as WiFi access points, which creates new WiFi
hotspots using a wired Ethernet connection.
1. Plug an extender into an electrical outlet.
Wait for the Power LED to light green. If the Power LED does not light,
press the Power On/Off button.
2. Use an Ethernet cable to connect the Ethernet port on the extender
to a router Ethernet LAN port or a remote Ethernet LAN jack with LAN
access.
The extender joins the LAN and creates a WiFi hotspot.
