Slow Internet - Errors coming from Motorola Modem

I'm experiencing internet slowness and I've had a technician come to check the wired connection to the house and he stated there was no issue. I'm experiencing slowness and drops with a wired and wireless connection. I checked my event logs in the Motorola Admin portal and saw a lot of Critial(3) and Warning(5) messaged:

• Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out
• SYNC Timing Synchronization failure - Failed to acquire FEC framing
• MDD message timeout

Are there any configurations I can change on my Modem or Router to deal with these errors? Working from home has been a nightmare the the internet dropping throughout the day.

Here is my setup:

• Modem: Motorola 24x8 Cable Modem, Model MB7621, DOCSIS 3.0
• Router: R6700v2 — Nighthawk AC1750 Smart WiFi Dual Band Gigabit Router

Any thoughts, comments, or advice?

Thanks!
