Intermittent Internet Connection

I am experiencing intermittent connection. I checked my modem SNMP Event log and it is filled with

"Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=e8:6d:52:45:25:e2;CMTS-MAC=00:1b:d5:fe:be:c5;CM-QOS=1.1;CM-VER=3.0; "


"Dynamic Range Window violation." for at least the past week.

It's been really hot here lately

Anyone translate for me?

    A T3 event indicates a time out in upstream communication. A few of these are normal but if they become frequent enough problems will be very noticeable and could be an indication of a signal or modem issue. Are there any cable splitters you can try bypassing to see if that helps?
