H820 - LED Light Information

LED Light sequence on boot-up

When the router is first powered on, the following light sequence is a good indication that the modem is set-up normally. WAN & LAN will come ON briefly then go OFF. The LAN will come ON and then flicker with traffic, the SYS led will come ON for approx. 1 Minute, then will start to flash consistently, then Wi-Fi LED will come on.

When a factory reset is performed on the router, this sequence above is also a good indication that the modem has reset correctly. Please see article on Factory Reset. 

If the router is experiencing issues, and the lights/ light sequence is different from the above this may be an indication of a fault.

Signal strength and internet connection

If a SIM card is inserted and the antennas are receiving signal, the signal light will flash blue. Once the correct APN settings of the SIM are entered into the router, an internet connection will be established and the cell light will stop flashing and be solidly ON. 

Signal Strength Indication - The signal light will flash blue when there is signal. The faster the flash, the stronger the signal. (see table below for details). More details of signal strength is found in the web GUI. Status > Network.

Information on all LEDs

-       If LAN cable is connected and transmitting data, it will be flashing.

-       If WiFi is enabled, the WiFi light will be solid on, and flickering if transmitting.

-       If VPN tunnel is not connected, light is off. If VPN tunnel is connected, light is solid.
