Intermittent loss of internet daily basis
My internet drops for a few minutes on a daily basis.
This started happening when I moved to a new address in the same city.
I own my own modem and support will not authorize a service dispatch to look into this and said I need to contact Arris for support.
Every time my internet drops I see these events on the modem (Arris SB6183)
Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=xx:xx:xx:xx:xx:xx;CMTS-MAC=xx:xx:xx:xx:xx:xx;CM-QOS=1.1;CM-VER=3.0;
Followed by this when the connections starts working:
Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out;CM-MAC=xx:xx:xx:xx:xx:xx;CMTS-MAC=xx:xx:xx:xx:xx:xx;CM-QOS=1.1;CM-VER=3.0;
REG RSP not received;CM-MAC=xx:xx:xx:xx:xx:xx;CMTS-MAC=xx:xx:xx:xx:xx:xx;CM-QOS=1.1;CM-VER=3.0;
My signal levels are:

I believe the T3 time-out error is a loss of communication from my modem to the CMTS and not sure how Arris support would troubleshoot this further. They want $39.99 to open a support case.
Does anyone have any suggestions as to what this error message means and how to get support from Cox?

Wow, Tier 1 by phone is getting pretty bad. The T3 errors are from noise/ingress on the upstream. I think the T4 errors are from you somewhat low downstream SNR but I am not sure. It should be above 35-36 but you power level is on the high side. Are you going through a amp or splitter of any kind? If you have a direct connection I would demand a tech. As long as it is a outside problem there should be no cost. If you are really worried, get Cox Complete Care for a few months to cover the cost.
