@David-TP
Hi David, thanks for your reply.
As requested, this evening I rebooted the router so I could take a screenshot of the internet status before it gets connected (as always, it's taking a long time to reconnect and is still offline). Below the screenshots of the internet status.


Below are the system logs from last night until midday (the router connected during the night and has been online all day). The logs show the time it actually connected to the network (2025-08-28 02:46:57) because it correctly updates the date and time from the internet (the previous date was 2016). It seems there were a few short disconnections of a few seconds during the day, but it reconnected right away on its own and I didn't notice.
