Have had this modem since Oct 2025. About a month ago, started getting frequent brief drops (~1 per hr). Doesn’t last long typically. Have checked with Xfinity a number of times when this happened and they show no issue with their line.

Would it be possible for you to connect a computer directly to the gateway using an Ethernet cable? This would help us determine if the internet drops only on the Wi-Fi, or if it affects both Wi-Fi and hardwired connections.
Make sure that the gateway is placed in an open area to minimize Wi-Fi congestion.
Also we recommend checking the cable signal levels within the gateway. If the signal levels are out of the acceptable range, they can lead to the kind of rebooting issues you're experiencing.
When the signal levels are within the recommended range, your gateway can maintain a stable, high-quality connection to the internet
Please refer to the link below for instructions on how to check your cable signal levels:

If you find that the signal levels are not within the recommended range, we suggest contacting your Internet Service Provider (ISP) to have them reviewed and adjusted as needed.
