Hello GEO714
I see you are getting T3 timeouts which may be a issues with noise on the cable lines they may need to send a tech out to check your lines.
T3 Timeout ( Ranging Request Retries Exhausted )
Explanation: The cable modem has sent 16 Ranging Request (RNG-REQ) messages without receiving a Ranging Response (RNG-RSP) message in reply from the CMTS. The cable modem is therefore resetting its cable interface and restarting the registration process. This typically is caused by noise on the upstream that causes the loss of MAC-layer messages. Noise could also raise the signal-to-noise ratio (SNR) on the upstream to a point where the cable modem’s power level is insufficient to transmit any messages. If the cable modem cannot raise its upstream transmit power level to a level that allows successful communication within the maximum timeout period, it resets its cable interface and restarts the registration process. This error message is DOCSIS event message is R03.0, Ranging Request

sending a *jpg in hope a Netgear Guru / Tech could confirm that captured channels and the levels that my c3700-100nas have locked onto are the signal strenght sent from ISP. Or am I having problems with modem capturing the signal. Was charged a fee last week, yet not positive they troubleshot problem, just swapped out a splitter and left.
What does your error log show
is there another log file other than Advanced>Admin>Logs ? only showing Dos attacks from Ping of Death. and DHCP issuing IP's to my wifi devices.

this was captured when internet failure last week. Am I looking at Downstreaming channels signal strenght / captured from ISP ...Upstream was extremely high and unlocked. Downstream unlocked channels and dBmv -15, -14, ... my understanding is if Upstream dBmv is above 45-50 this causes Downstream and connection failures.
