We have one main box and 3 mini boxes. The left light on ALL the mini boxes is blinking green. This started a few days ago. It is not happening on the main box -- only the minis. TV channels and DVR seem to be working okay.
I have followed all suggestions to fix -- rebooted ALL boxes and router. More than once. The lights restart as normal, then in a few minutes start blinking green again.
Any idea how to fix this?
