SYNC Timing Synchronization failure - Loss of Sync - Slow Speeds, Drops, etc
Hello,
I have the "Ultimate" Internet tier and over the last few days, my service has been atrociously bad. There are times when I get close to the speeds I am paying for and other times not even close. I was wondering if my power levels on my modem were in-spec?
Also, seeing quite a few of the following log messages in my modem:
SYNC Timing Synchronization failure - Loss of Sync
Started Unicast Maintenance Ranging - No Response received - T3 time-out
MDD message timeout
