        Yes, I need help, I see lots of T3 time out and T4 reboot of modem automatically happening, the issue is not getting resolved for me

      SNR isn't great but it's technically within specs. I don't know if I trust those power levels. All channels perfectly 0 dBmV doesn't seem possible. Maybe someone from Cox can confirm those levels. This doesn't look like an easy answer.

    I've checked the surrounding area and not showing any issues the would be affecting the modem. Check the modem signal levels and they're not at the levels we like seeing them. You mention you have tried different modem. Have you check the coax cable and make sure there are no kinks and the conductor (copper pin ) is bent or just try swap the coax if you have a spare?

      I tried different coax (new fresh out of pack no kinks) and also tried another room, got different power level but still same disconnect

        You posted firewall/router logs but you need to post cable modem logs. Also look at the high error rate on channel 2/927 MHz. Possible RF ingress.
