![]() It could be the ISP or the modem defective but not as likely. Generally this is caused by cabling issues. There was no system overload, at the time only two devices were using the network. ![]() This error message is DOCSIS event message is R04.0, Ranging Request. Typically, this indicates an occasional, temporary loss of service, but if the problem persists, check for possible service outages or maintenance activity on this particular headend system. The cable modem is resetting its cable interface and restarting the registration process. T4 ( Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received )Įxplanation: The cable modem did not receive a station maintenance opportunity in which to transmit a Ranging Request (RNG-REQ) message within the T4 timeout period (30 to 35 seconds). This error message is DOCSIS event message is R03.0, Ranging Request. 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. Noise could also lower 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. This typically is caused by noise on the upstream that causes the loss of MAC-layer messages. The cable modem is therefore resetting its cable interface and restarting the registration process. I looked it up and this is what I came up with :Įxplanation: The cable modem has sent 16 Ranging Request (RNG-REQ) messages without receiving a Ranging Response (RNG-RSP) message in reply from the CMTS. ![]() Mon Jul 14 10:41:35 2014 Critical (3) Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out CM-MAC=b0:77:ac:92:7c:2e CMTS-MAC=00:01:5c:22:04:0c CM-QOS=1.1 CM-VER=3.0 Mon Jul 14 11:40:05 2014 Critical (3) Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out CM-MAC=b0:77:ac:92:7c:2e CMTS-MAC=00:01:5c:22:04:0c CM-QOS=1.1 CM-VER=3.0 Time Not Established Notice (6) WiFi Interface set to Channel 6 (Side-Band Channel:N/A) - Reason:INIT I am getting this text in my router event log: How do i fix this?
