Event Log with Continual - Started Unicast Maintenance Ranging - No Response received - T3 time-out
Hey All - I came home tonight to some unresponsive internet (<10mb down and 0.03 up) and when I checked on the event log, it had the dreaded "Started Unicast Maintenance Ranging - No Response received - T3 time-out" message occuring over & over. After repeated power cycles, signal resends, etc., it would clear up for 10-15 minutes then back at little to no performance. Four hours later of troubleshooting, I couldn't make any headway with phone tech support as I own the modem (that was the initial response of its the modem's fault).
In years past when this has occured, the only way I've gotten this straightened out after many calls & tech support visits was eventually getting new line drops. Was wondering if there was any ideas on what how I can help point tech support in the right direction or talk to the team at Comcast to get this properly diagnosed as the base tech support can't see anything on their end.
After doing more reading tonight around the upstream & downstream levels, it looks like downstream power is a bit high across the board, but all else is in acceptable tolerances. Any ideas on what I could do to try & get this straightened out (again) or anything that can be done on my own?
