RBR50. DVR does not work with AT&T U-Verse

- The DVR came with the AT&T U-Verse set-up. It is part of my TV setup. I use the Record button on my remote to record and the DVR button on my remote to see the list of the programs I recorded. It is not a separate installation,

-.I use the DVR option to record TV programs for viewing later.

- The DVR always works when I don't have the Orbi connected.

- I have done nothing to change the AT&T modem. I plugged the Orbi into the AT&T modem per directions.

- I have done nothing to change any internet connection.
