The people with whom it has not work at all, the device has a power switch at the back directly via the power jack, small round button. Did I also wondered why the unit does not work at the beginning. Press this button first. Otherwise the receiver does it all automatically. Reception is good to very good, except for the HD channels here freeze on the images, the sound, and so on, apparently the HD Encryption is too complex for my power lines. As accessory for the basement or bedroom where no antenna connections are available, it is best, not suitable for HD channels and PayTV, lack of card slot.
