EZR13 WiFi extender has 2x WiFi antenna sockets and 1x PoE sockets.
The WiFi antenna sockets are N-female connectors on the top side. The PoE socket is on the down side.
From left side, there are DC socket, Reset button, PoE & WAN, LAN, Indicators, and USB.
There are four indicators on the EZR13 extender. From up to down, the left sides are system & Wi-Fi, and the right side are WiFi relay & WAN. Below are the indicator descriptions.
This light indicates that the extender is receiving power. If it's lit solid green, then the router has booted successfully.
The extender system is booting up. The system indicator flashes while resetting or flashing the firmware.
No light at all indicates that the extender is not receiving power. Check the PoE socket connect to the motherboard and check the PoE adapter. You might need to test an alternate power socket if the router doesn't power on.
This light indicates that the modem is sending a Wi-Fi signal. If the light is on the green, you should be able to see and connect to the Wi-Fi network.
If you are connected to the Wi-Fi hotspot, it will flash green to indicate data going to and from the extender. If the extender is connected to another Wi-Fi hotspot (Wi-Fi relay), it will also flash because it has the data flow.
If it's off, your extender is no longer sending a Wi-Fi signal. You can log in to the extender admin and turn on the Wi-Fi master hotspot.
Relay & WAN
These lights indicate the extender is connecting to another WiFi hotspot via WiFi relay or WAN on LAN cable.
