Dear Team,

I have a ZTE modem that provides the internet connection.
Connected to it, I have an AX72 router that handles the wireless signal.

On the ZTE (from the ISP), Wi-Fi is disabled.

Every day between 11:00 PM and 12:00 AM, both wired and wireless internet drop. However, when I test the ZTE, the internet connection is working normally.

I’ve already tried changing the port on the ZTE, but the issue persists daily.

To restore connectivity, I need to restart the AX72.
When I connect via cable to the AX72, it receives an IP address but cannot access the internet, and its management interface also becomes inaccessible.

Device details:
AX72 V1 – Firmware: 1.2.8 Build 20250731 rel.60987(5553)

Log entry:
01:13 – This was the time I restarted the device.
