How to setup Vodafone 3G USB Modem with DrayTek Router?

 
 
Setup Guide:
 
Introduction
 
With the latest firmware, a 3.5G HSDPA USB modem (such as the Vodafone USB modem) can plug into the Vigor2910 USB port and operate as one of the WAN ports. Load Balancing (the internet traffic is spread across multiple WAN ports) and Fail-Over (when the secondary WAN is used only when the primary WAN is not available) are both supported. Because 3.5G uses wireless which has a very good mobile coverage, it can make an effective emergency backup connection.
