Hello all, recently I bought a new Powerline since my old one had some problems. Setup was easy like always, but I have experienced a problem - after pairing, wneh the power and Powerline LED are solid on, the Ethernet LED start blinking turning Internet on and off. Sometimes it will light on for couple of seconds but then it will start blinking on/off again resulting in no internet connection. Can you help me trouble shoot this? 

I tested in different sockets, different cables. My internet card in computer is fine, since other TP-Link products with wired connection works fine.
