This document is the installation guide for the TP-Link TL-R406 wireless broadband router, which introduces how to connect the router, set up the computer, and connect to the Internet.
The guide starts with hardware connection instructions, showing how to attach the ADSL or ISP broadband line to the WAN port, check the SYS and WAN indicator lights, and place the router on a flat, ventilated surface. It also lists the items included in the package such as the router, power adapter and warranty card.
Next, it explains how to set up a computer’s network parameters, run the router’s web‑based setup wizard, choose the appropriate WAN connection type (PPPoE, static IP or dynamic IP), and configure LAN settings. Additional sections cover resetting the router to factory defaults, using the router as a switch, and common troubleshooting steps for login issues and connectivity problems. This manual is written in Chinese.

Disable DHCP on the secondary router, set its LAN IP to a free address such as 192.168.1.254, and connect a LAN port of the secondary router to a LAN port of the primary router.
Ensure the computer is connected to one of the router’s LAN ports, the LAN and router IPs are in the same subnet (e.g., 192.168.1.x), and that the web browser is not set to use a proxy or dial‑up connection.
