Hello,
We have a VMG4381-B10A with Cincinnati Bell. The modem regularly drops the internet connection. it appears to be mainly when an iphone or a macbook is used. The drop time is from a few seconds to a minute. It can happen very quickly. The drop is best detected by Net Uptime monitor which pings 3 websites on 1 second intervals. We have had Cincinnati Bell out here numerous times. The signal levels and all are fine. The modem has been replaced multiple times. They have tried turning off IPV6. Nothing has helped. The issue is generally not seen when just a PC is active. This renders the Apple devices almost useless for a number of applications.
here is one sample of drops:
