Intermittent Wi-Fi speeds - dramatic slowdowns

My Wi-Fi connection speeds vary throughout the day from over 800Mps to less than 2Mbps on devices that are stationary throughout the house.

Motorola MB8611 modem keeps restarting - firmware issue

I have owned my own Motorola MB8611 cable modem since September 2022, and since the middle of December 2022 it has been restarting multiple times per day. After a lot of troubleshooting, I figured out that it is related to the firmware, aka software. With Firmware 8611-19.2.20 it is stable, but then

DOCSIS 3.1 Modem not provisioned correctly (DOCSIS 3.0 QAM 256 Channels vs DOCSIS 3.1 / OFDM)

Why is new Motorola MB8611 is providing lower upload than the old MB8600?

XB7 vs XB6 initial performance disappointment

My wired download speed on the XB6 was over 1100 Mbps. The wired speed on the new XB7 caps out at 950 Mbps. Is this modem relatively deficient, or has the overhead cushion on my gigabit service been eliminated? The wireless speeds are also not as robust throughout the house as the service I enjoyed
