Introduction

The TP-Link Travel Routers provide dual-mode USB connectivity (configured as USB Modem Mode for 3G/4G dongles or USB Tethering Mode for mobile devices) to establish reliable internet access via their USB interface. This article provides step-by-step instructions for configuring the router to these two modes effectively.

Configuration

In 3G/4G/5G USB Modem mode, the router shares the data from a 3G/4G/5G USB modem with other devices. And in USB Tethering mode, the router shares a mobile device’s cellular data with other devices. The two modes are suitable for travel.

If it doesn’t match your network environment, identify which operation mode is suitable for you first.

QA

Q1: Can I still use the USB sharing function when the router is operating in USB Modem Mode/USB Tethering Mode?

A1: No, the USB sharing functionality is unavailable during USB Modem Mode or USB Tethering Mode operations.

Q2: When using a mobile phone to log in to the web management interface to configure Tethering mode, is it possible to use the same mobile phone as a tethering mobile device and connect it to the router's USB port via USB cable?

A2: No, the mobile phone cannot simultaneously function as both a configuration device for the router's management interface and a tethered internet source. When activating Tethering mode, the USB interface dedicates its resources exclusively to establishing modem functionality, which conflicts with the concurrent requirement for administrative access to the web interface.
