Internet interruptions

I have been experiencing drops in internet over the last several days. Under my modem event logs there are errors such as T2 timeout, T3 timeout, and SYNC Timing Synchronization failure - Loss of Sync. I can sent a screen shot to show the numbers if need. Thanks.

    Your signal levels would be more useful, specifically your upstream. It needs to be below 50dB. Also, any splitters in the house between the street and the outlet the modem is on?

      No there is not splitters in the house. Here are the upstream numbers

        Looks like a issue with the OFDMA channel. Not only is the power level on the low side but it isn't locked and is the same frequency of your first channel(36.8Mhz). My guess is they are growing pains of a mid-high split upgrade. Have you tried a factory reset of the modem? If so, I would suggest a technician.
