In a few weeks I will be moving to a complex which offers free Wi-Fi. Will I be able to stream movies and get the HD menus on my premiere utilizing the complex's free Wi-Fi? If not, can I get the HD menus on the apartment's Wi-Fi and stream Netflix using a router...or, is it one or the other? One last question: I do realize I have to repeat the guided set-up. I will be going from a Comcast system to Time Warner. Everything works fine right now. Do I have to give up the M cable card to Comcast, or can I keep it and just give the serial number to Time Warner when I do the guided set up?
