Sorry if this has been answered a hundred times. I have a Roamio Plus in the living room connected via wifi (no Moca). Can I add a mini in my bedroom and just use wifi instead of adding Moca to the Plus? Connection speed is very good on the Roamio so I'm assuming it will be fine with the mini. Also, does Tivo still offer lifetime on Mini for $150? I have lifetime on my Roamio if that matters. Thanks in advance ETA: Will I still need a TA for the mini?
