Just beware, if you’re in a place where you can only get DSL and coax or fiber are not available - Powerline does use the same frequencies as DSL and both the power cables and your landline are unshielded wires. So there will be cross talk and powerline can and probably will affect your DSL connection. Also depending on your cables and the powerline adapters you use, you may disturb radio stations in a wider area around your house.
