Since March 3, all channels on QAM 114 have been intermittently pixellating or freezing, making those channels unreliable or unusable. STB's reset, cables checked, ONT rebooted, nothing worked.
Since 5/8/20, these channels have been completely unusable.
Does anyone know if this is a known issue, or why only one particular QAM is having problems when all the other channels are fine?
