User Manual
Connect MerryIoT Hotspot
You can connect to the gateway via WiFi interface which the SSID and password printed on the back label by default. The rule of gateway SSID is MerryIoT-xxxxxx where the last digits are the last 6 digits of the MAC address The PC will fetch IP address of range 192.168.4.x except 192.168.4.1 assigned by the AP.
Hotspot Setting
Open the web browser(ex:Chrome) after connect to the gateway via IP address “192.168.4.1”
Now you can configure the gateway through the WEB UI.
STEP 1 : SET WAN
The gateway support either “Ethernet” or “Wi-Fi” connection as the internet backhaul.
STEP 1.1Ethernet Setting
Configure the IP address of WAN.[Static IP/DHCP client]
ETHERNET STATUS – The information of IP address/Subnet Mask/Gateway/DNS.- ETHERNET SETTING – Configure the IP address of WAN.[Static IP/DHCP client]
- Static IP – Setup the IP address/Subnet Mask/Default Gateway/DNS of the static IP.
ETHERNET STATUS – The information of IP address/Subnet Mask/Gateway/DNS.Contact to the network administrator for the static IP address information.
DHCP – The IP address/Subnet Mask/Default Gateway/DNS will be assigned by the DHCP server.
STEP 1.2Wi-Fi
Select “Wi-Fi” to be the internet backhaul connection.
The gateway WiFi interface is the Access Point by default which SSID is “Femto_Lite-XXXXXX” printed on the back label. Administrator can only access to the WEB UI through the Access Point mode to configure the gateway. The gateway will be the WiFi client and won’t access to the WEB UI after enable WiFi interface as the internet backhaul connection.
MANUAL CONNECT–Specify the remote AP SSID and enter the password if necessary.
Click “Join” to accept or “Cancel” to abort.
The gateway will scan the neighbor access point automatically. Just click the SSID for the WiFi connection.
Enter WiFi password if it is necessary for the connection.
Click “Join” to accept or “Cancel” to abort.
