My concern was to convey my music files from my computer to my HiFi who was removed in a house with thick walls and several levels. I did not very conclusive tests first, since the sound was often cut, but that installed PLC adapters on which I could connect terminal, I could solve the problem without difficulty. So in short distance wireless, it works very well; greater distance and thick walls, using Powerline. The mode job is not super clear, but a little fiddling you get there because ultimately it's not complicated at all. I do not regret my purchase.
