In the Ezhotspot Extender, there is a built-in failover feature.
With the Ezhotspot Extender, you can concurrently:
1. Connect a LAN cable from a ADSL/Cable/Fiber Modem to the WAN port of the Ezhotspot Extender
2. Wirelessly connect to to a remote wireless network
3. Connect a 3G/4G dongle to the USB port or tether a smartphone to the Ezhotspot Extender
all at the same time!
The priority is by default configured as such; WAN ---> Wireless ---> USB manner.
This priority can be overrride by using the Gateway Override function.
For example, when you have both an existing wireless joined connection and a 3G/4G dongle connected, the priority is always given to the wireless connection. When you lose the wireless connection to the remote hotspot, the internet is automatically switched to the 3G/4G. When you have joined to a new remote wireless network, the internet again is reverted back to the remote wireless hotspot. This ensure that no 3G/4G data is unnecessarily used.
Note: The failover will not automatically revert back to a wireless network. A new wireless scan and successful joining is required before the the gateway is switched back to the remote wireless network
