3.1 Connect MerryIoT Hub

You can connect to the gateway via WiFi interface which the SSID and password are printed on the back label by default.

WLRGFM-100 - Figure 4

Figure 4 – Back Label

The rule of gateway SSID is MerryIoT_Femto_Lite-xxxxxx where the last digits are the last 6 digits of the MAC address

The PC will fetch the IP address of range 192.168.4.x except assigned by the AP.

3.2 MerryIoT Hub Setting

Open the web browser(ex: Chrome) after connecting to the gateway via IP address “”

STEP 3.3.2 Wi-Fi

Select “Wi-Fi” to be the internet backhaul connection.

WLRGFM-100 - Note The gateway WiFi interface is the Access Point by default which SSID is “MerryIoT_Femto_Lite-XXXXXX” printed on the back label. The administrator can only access the WEB UI through the Access Point mode to configure the gateway. The gateway will be the WiFi client and will not be able to access the WEB UI after enabling the WiFi interface as the internet backhaul connection.
