Bought used lifetime Tivo HD from reputable seller on ebay. We cannot get thru guided setup. It stalls on "getting info" and says "connection interrupted with code N11" we've tried---wireless connection, wired, phone connection (and a phone connection at a friend's house). It always gets to the same spot and stops. Tivo says they can see it makes a connection, just doesn't hold it. Is this a hard drive problem? We've done power cycling, kickstart codes, router port openings, etc. Trying to decide whether to return it to the seller and find another one or if I'm missing something. Thank you!
