I have purchased a Roamio Pro and a Mini. The Roamio will be in the living room and the Mini in the study area. I have a wi-fi set up in the study. Does everything I need to get set up and going come pre-packaged in the Roamio and Mini? Stated another way-- will I need to buy anything else? For previous Tivo set-up I needed to purchase a wireless adapter. Will I need any MOCA adapter? I am aware that I will need one cable card (from Comcast). I do not plan to use any ethernet cable or other cables from the router to either the Roamio or Mini.
