I have observed the Wireless LED blinking on and off several times and all others are off during normal operation.  Modem will automatically reboot successfully after that happens.  This has been happening quite often lately.  Attached is the latest event log.

    You’re having line issues according to the logs. 

    Got a screen snip of the cable connections page (shows upstream/downstream values)

    Here is a snip of latest values.  I have noticed the SNR as low as 27.5 dB just a few days ago.

    well, that shows 1 of the many channels. 

    But even based on that and the log, you have line issues. your signal is a bit high and more than likely has issues. Check the coax within the home to make sure there isn’t any issues. If there’s not, the ISP will need to check it.
