Hello, everyone!

For the past 3 days, I have been experiencing recurrent (every few hours) disconnection of the WAN of the router with the LED indicator for WAN turning orange, despite the functional internet connection on computers directly connected to the ISP modem-router. I have not needed to reboot the modem, just the router, to restore the connection. However, I have tried rebooting both the router and modem as well but it hasn't helped.

The router was purchased just last August, and had been working well before, This issue was first encountered after I enabled the reboot schedule last Saturday (Sept 19), which I set to 4AM on Sunday. I've already disabled this feature, but the issue persists.

I have already updated the firmware since the issue started, and have tried the community recommendation to clone the MAC address of this computer that I had connected directly to the modem-router, but neither have helped.

Each time this happens, system log of the router says 3 things, all "Type: Led Controller" and "Level: Info":
1 - [1413] Start to run LAN_ON
2 - [1413] Start to run WAN0_OFF
3 - {1413} Start to run WAN1_ON

I'm attaching a screenshot here for reference. Please note that the system time was not updated until the last reboot.

Hoping to hear your suggestions. Thank you!
