Today is Saturday 6 November. I wanted to give you an update to the rebooting issue. Today, the box did not reboot once. The same thing happened last Saturday morning as well.
I really do not think it is an electrical issue, unless it is also caused by the construction outside of my apartment.,
It seems pretty obvious to me, that there is something wrong with the cables outside the building,. Every morning there is work happening, the cable box reboots. Whenever there is no work happening, the box has no problems.
