said by cprgolds:@Mike_W -- I have a Roamio and 3 minis hooked up to Frontier. I still use the Frontier router, but I can't see any reason why your plan will not work. I also run a second router off of one of the FTR Router ports. All in all I am very pleased with the Roamio/Minis.
You won't be able to get Frontier's On-Demand or PPV over the TiVo stuff, but that may be a good thing.
Why the Frontier DVR? I'd ditch that too unless you have a specific reason for it.
You didn't mention tablets or cell phone access? TiVo wants to be on the same subnet for wireless to work well.
I didn't want the Frontier DVR, but they said it's free for the first year and they wouldn't give me any credits if I declined it. So I decided to take it for one year, but it might never get used.
I know I won't get any On-Demand programming. Not a huge deal for me, but the Tivo does work with Comcast's On-Demand so maybe I'll change TV providers down the road if the need for On-Demand increases.
Everything will be on the same subnet and I have a slingbox for remote streaming in order to bypass all restrictions.
