I've been having an issue with my powerline kit where the connection drops out after a few hours. All three lights are green on both devices when this happens. I have contacted the tech support via email and have not heard back after they said they would elevate the issue to someone who would know more about it. The strange thing is the way you go about fixing this problem. I have TP-PLC installed and to regain the connection, I have to enable and then disable the power saving mode on both devices and then it will work again until who knows when. I've noticed when this happens Windows recognizes it as a new network most of the time so the network I am connected to is "Network 14".
