Network Modes and WAN Backup
The MB130-4G primarily operates as a 4G LTE Wi-Fi router. It also supports a WAN connection for flexibility.
- 4G LTE Mode: When a valid SIM card is inserted, the router automatically uses the 4G LTE network for internet access.
- Router Mode (WAN Backup): If you have a wired internet connection (e.g., from a cable or fiber modem), you can connect it to the router's WAN/LAN port. The router can then use this wired connection as its primary internet source, or as a backup if the 4G LTE signal is unavailable.
