Are you facing intermittent connection issue using direct connection or the issue is happening only on the Wi-Fi connected devices?

In Wi-Fi both the networks are affected 2.4 and 5G as well or only one?

when the internet drops did you noticed the LED on the modem is going off or changing color or flashing?

I lost internet through both WiFi signals and wired connections. Multiple times daily. Only resolve is manual restart. No change on LED until restarted.
