Unused, nearly new, powerline kit for Lan connection over existing home electric circuit. For example from 5G router to a distant computer. Fast reliable connection, very simple to pair them. I could not use them as I wanted in my home configuration, this is why I am selling. I am using similar devices in another flat and they work very well. I have a 5G router near a window so the signal is weaker on other side of apartment. This allows you to make a Lan connection from the router via the power circuits. Please do your research to see if it will work in your home setup. I can not take returns. The power line can only work in the SAME ELECTRICAL RING MAIN. If you have multiple separate ring main in large house this may not work in all the house. Please check your electrical setup before purchasing.
