Cellular WAN (3G/4G) Backup
Connect a supported cellular USB dongle with an active SIM card to the USB port. This adds a second
WAN interface and allows the Zyxel Device to wirelessly access the Internet via a cellular network. The
cellular WAN connection is a backup in case the DSL/Ethernet/Fiber connection fails.
To set up a cellular connection, click Network > Broadband > Cellular Backup.
To update the supported cellular USB dongle list, download the latest WWAN package from the Zyxel
website and upload it to the Zyxel Device using the Maintenance > Firmware Upgrade screen.
