All Tivos in the house just decided to drop connection to the other boxes in the house. Tivo is no help, they say restart the network (did that), restart the box (yep), force a connection to Tivo (yep) and the final one was to unplug the ethernet cable and plug it back in (WTF)

The boxes all have IP addresses and can connect to the Tivo service and stream from apps like Tivo. I turned on something called "control over network connection" but i think that is for Bolts/Minis and can't figure out how that would affect show sharing between boxes.

All boxes show up in the account dashboard and have sharing checked. Do the media access keys have to match on all boxes? I found one that didn't match the others but that doesn't explain why all of the other boxes don't work.

Hardware is a mix of Bolts and XLs all running the latest firmware. I hate thinking that I may have to default these things and rerun guided setup.
