I have DSL with a modem supplied by my telco. It has four ethernet ports on it. If I want to add wi-fi. Can I just get some kind of gizmo (and what is it called) plug that into one port and be good to go for providing a wireless connection to a stand alone internet radio.
Telco will do it, but they charge to set it up and charge "rental" on the dsl/wifi gateway for as long as I have it.
