Firstly, in order to obtain Internet, please complete the next steps:

    1) Power off your modem, connect the Router's WAN port into your modem using an Ethernet cable.

    2) Power on the Router, when the Router is fully powered on, power on your modem.

Since the Router is designed to be plug-and-play, it should already have Internet when you complete the above steps, the default Internet connection type is "Dynamic IP" or "DHCP".

If your ISP provides different Internet connection types such as PPPoE, you will have to manually configure it to obtain Internet.

Through the web management interface of the Router (recommended)

    1) Connect a PC to the Router, either connecting by Ethernet, or connecting to the default Wi-Fi of the Router, the network name looks like TP-Link_XXXX, the default Wi-Fi password can be found on the label of the Router.

    2) Open a browser on your PC, type "http://tplinkwifi.net" in the address bar, access the router's web management interface, you will be asked to set an admin password, please remember this password well.

    3) Follow the instructions on the web page to setup your new TP-Link Router, the Internet connection details can be obtained from your Internet Service Provider.
