2gb Internet
Noticed huge drop in internet speed, from about 900mbps to 80mbps. Rebooted everything, same thing. Looked at my Motorola MB8611 event log after reboot, found these 2 errors:
| Time Not Established | Critical (3) | SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing |
| Time Not Established | Critical (3) | UCD invalid or channel unusable |
I also found out that even though I supposedly have the 2gb plan, according to my bill since February 2026, Xfinity thinks I only deserve 100mbps. It's been like that since March; behold:
I mean, REALLY?
I definitely need some help with this.

Concern moved here to the Customer Service help section for greater exposure to Comcast corporate employees (The Digital Care Team) for assistance.

To send a "direct message" / "private message" message to Xfinity Support:
• Click "Sign In" if necessary
• Click the "Direct Message" icon
• Click the "New message" (pencil and paper) icon
• The "To:" line prompts you to "Type the name of a person". Instead, type "Xfinity Support" there
• As you are typing a drop-down list appears. Select "Xfinity Support" from that list
• An "Xfinity Support" graphic replaces the "To:" line
• Type your message in the text area near the bottom of the window
• Press Enter to send it
