The powerline LEDs light up on both the adaptor and the extender, except for the internet light. The TP_LINK network appears in my list of Wi-Fi options, but when I select it, I have no internet connection. I've confirmed that the internet is coming through the Ethernet cable by connecting it to my laptop. I've also followed all the troubleshooting suggestions on the website, including rebooting the powerline units and the modem. Yet I am still unable to obtain internet on the extender. Has anyone found out how to overcome this issue. I just bought this unit and hate to have to return it.
