Daily Upload Failure / Intermittent Sync Loss
Service Issue: Daily Upload Failure / Total Sync Loss
Time Window: Daily at approximately 6:30 PM
Prior Troubleshooting:
I have already had two technicians out to my home. They checked my signal, but because the issue is intermittent and time-of-day specific, they were unable to find a fault during their visits. It has become clear that this is issue somewhere else.
Technical Diagnostics:
My modem logs are currently flooded with the following critical errors during the outage windows:
SYNC Timing Synchronization Failures: Failed to acquire QAM/QPSK symbol timing.
Consecutive T3 Timeouts: Persistent "No Ranging Response received" (16+ consecutive instances).
Request for Escalation:
Because two residential technicians have already cleared the house, I am requesting that this be escalated to a Maintenance/Line Technician.
Thank you for your help in finally resolving this persistent issue.
