You mean you are unable to connect the WiFi network, or the WiFi is connected but no internet access?

For orange Internet light issue on the router:

    1. Unplug your router from the modem, and connect your PC directly to the modem to verify the Internet status of your ISP.

    2. Reboot the ISP Modem and the Router, you must firstly power on the Router, once the router's fully powered on, power on the modem.

    3. Login to the web UI of the router via http://tplinkwifi.net and set it up following the Quick Setup.

    4. If your PC has Internet when connected to the modem, but the Router still doesn't, please go to Advanced > Network > Internet > Mac Clone to clone the Mac address of your PC.
