4.3. NETWORKING MODE
4.3.1. WAN+LAN+4G
In this networking mode, user can access internet through WAN interface and 4G interface. WAN
interface has higher priority than 4G interface to ensure communication and save 4G flows.
When WAN interface occurs problems, router can change to 4G interface to connect internet. In
this mode, user can also connect to router through WIFI.
To achieve this mode, user don’t need to change the router’s parameters. Just connect the cable
to router and insert SIM card, then power the router.
