Just got a powerline adapter TL PA511 from my uncle. I am using TL-PA4010P at my home already. At first the TL-PA511 will connect to my TL-PA4010P but after 30 seconds it will just shut off. I tried pressing the pair button and it would do the same exact thing. But now, everytime I plug it in it will not show any led lights, however if I plug the PA511 to my computer, the Power LED will start blinking, and in Windows be detected howver in tpPLC it won't be detected. Any suggestions on what to do?
