Slow internet speed Sync Timing Synchronization failure

I’ve been experiencing a slow speed of internet for quite awhile now. I just checked my event log, it seems I have a recurring issue. About 20 instances of the below error:

SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing;;CM-MAC=[Edited: "Personal Information"];CMTS-MAC=00:00:00:00:00:00;CM-QOS=1.0;CM-VER=3.0;

any thoughts on what it might be?

If you want to troubleshoot this yourself, please see Internet Troubleshooting Tips. If you still need help, please post your Internet plan speed and the following information from your modem or gateway:

model number
downstream power levels and SNR
upstream power levels
event log (Be sure to remove or blot out any MAC addresses. Forum security processing considers them "personal information" and may prevent the event log from posting if these are present.)
