What is disadvantages to broadband over power line?
Please be informed that a Powerline is a device that converts Internet connection into an electric signal for it to be transmitted through a wire. So, if you house uses different wirings for each room or each place inside your house, then there is no way that a Powerline connection will work on your system. Circuit breakers can also be affecting your connection. If your house is indeed using the same wirings that connects to every power outlet in your house but you have a lot of circuit breakers that could filtering the electricity passing through those wires, then a Powerline will not also work in the type of connection you want.
