Every morning for the past few days the tv connected to the main modem box is not working. I get a source message and make sure it is connected to cox then I unplug the box for several minutes and reset the wifi. The message on the box says boot and it take over an hour and several attempts with this procedure before the tv connects. The other tvs are able to work but saved recordings are not available until the main box finally connects. I think the main box is going bad.
