Chapter 1 Introducing the VMG
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 VMG to wirelessly access the Internet via a cellular network. The cellular
WAN connection is a backup in case the DSL connection fails.
To set up a cellular connection, click Network Setting > 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 VMG using the Maintenance > Firmware Upgrade screen.
File Sharing
Use the built-in USB 3.0 port to share files on a USB memory stick or a USB hard drive (B). Use FTP to access
the files on the USB device.

Media Server
You can also use the VMG as a media server. This lets anyone on your network play video, music, and
photos from a USB device (B) connected to the VMG's USB port (without having to copy them to
another computer).
