6.3 The Cellular Backup Screen
The USB port (at the side panel of the VMG) allows you to attach a cellular dongle to wirelessly connect
to a cellular network for Internet access. You can have the VMG use the cellular WAN connection as a
backup. Disconnect the DSL and Ethernet WAN ports to use the cellular dongle as your primary WAN
connection. The VMG automatically uses a wired WAN connection when available.
