How to make evry room phone jack receiving the DSL signal?
My house every room has phone jack. If one room is connected to the phone service, all other rooms phone jacks can receive the phone signal. Now I installed the ATT DSL in one room but other rooms phone jacks cannot receive the DSL signal by connecting the Modem. I do not know why. Can you explain it? Is it possible to make every room phone jack receiving the DSL signal by connecting the modem? I can move the modem to any room.
