5.3 Set Failover connection
5.3.1 Overview
By configuring the Failover function, you can set parameters of the internet connection mode
other than the current one. If there is a network failure, the router will automatically switch to an
available internet connection mode, therefore ensuring an uninterrupted internet access for clients
under the router.
Before setting the Failover function, ensure that you insert a SIM card into the router, and connect the
WAN port of the router to the internet at the same time.
To access the page, log in to the web UI of the router, navigate to Internet Settings, and locate the
Failover Settings part. This function is disabled by default.
When the failover function is enabled, the page is shown as below. You can configure the failover
connection by referring to Access the internet through the WAN port.
5.3.2 Example of setting up Failover connection
Scenario: You used to insert a SIM card in the router to access the internet, but you install a smart
home gateway after subscribing to the broadband service recently.
Goal: Set the router to access the internet through the broadband, and use the SIM card as backup
in case of broadband failure.
Solution: Connect the broadband to the router and insert the SIM card into the router, and
configure the Failover function.
Assume that the ISP provides a PPPoE user name and PPPoE password for setting up internet
connection.
