This guide will show you how to configure the Vigor2210router to enable 4G communication via an attached 4G USB modem. The 4G modems that this guide will apply to are:

  1. Optus – Huawei E3276 4G USB modem

  2. Telstra Prepaid – ZTE MF823 4G USB modem (use Vigor2120 firmware version 3.7.5.4)

(Vodafone prepaid – K5150 4G USB modem currently not supported)

In the Vigor2120 the USB modem will only run in Backup mode.

Step 1 – Enable USB WAN port

Go to WAN >> General Setup configuration menu.

Select Yes for Enable option.
