I recently purchased a TiVo Roamio OTA - 1 TB with All-in (Lifetime) Service I can't get it to work. I keep getting stuck on the setup page where it says downloading info then I get the error: connection interrupted. I get this with the wireless or ethernet cable hooked up. I called the internet provider to have the ports opened like the error says re-started the router & still the same thing I can't get his god dam thing to work. technical support told me to return the box so I did & got another one & it's doing the same exact thing. other things in the house work fine on the wireless system. what's the problem? any ideas? I got spectrum high speed internet & the router is new....
