U-verse recordings disappearing

We recently upgraded to fiber after they continuously kept hounding it’s about it. That required moving all of the equipment to a back bedroom and every since we have made the switch it has been nothing but a disaster! We had 80% or more of recordings and all of a sudden that started  randomly disappearing until they were all gone. They sent us a new dvr box and all was good for a couple of weeks and it started again. When we go to recordings it says they are unavailable and when they show back up, a number of them have disappeared. They will all be gone by the end of the day. Anyone else have this problem and how do we fix this?  Thank you!
