Thank you for reading this. I am about buy a new cordless phone set. I don't want to cause interference with my current (PowerMac 2.7) airport card, my Linksys wireless router nor whatever upgrade I may hve to get (new Airport Extreme card/unit/?) to work with Apple TV. The reality is I barely ever use the home phone, so quality is not important to me. What is vastly more important is not interfering with wireless computer/Mac stuff. My understanding is that wireless routers and such use the 2.4 frequency but may go to 5.8. Should I just play it safe and get a 900mgh (?) phone. Thank you for reading this. I know my terminology may have been incorrect. I greatly appreciate anyone's thoughts/advice.
