NTP - Time Server Sync Frequency

Pfter checking my router logs, it appears that the router is synchronising the time with the Netgear NTP server every 30minutes & sometimes only 5minutes after a sync.   Is this expected ?? 1 time...

No, completely wrong. The NTP time sync happens every time the router does connect to the Internet successfully. Best guess, you use an Internet onnection requiring authentication, and the router is configured with a Idle Timeout and Connect on Demand. This is wht kills your Internet connection, and when the next time Internet connection is required, the router does dial-up, and the NTP time sync follows.

My internet is a permanent cable connection & at 7pm at night I would expect the connection to the internet to be running heavily with Sonos, YouTube, kids iPad's, Netflix, Xbox etc.
The household uses internet heavily & has lots of connected devices which was the main reason for wanting the Wi-Fi6 router.

I'll check my modem/router logs tonight to see if it is shows any IP reassignement or internet connection information.
My modem is also assigning the network IP addresses so the RAX80 is in access point mode.

I found a similar post in an old forum for the R8000 router & there was an reply from a Netgear support saying that a time sync every hour was a function of the router.

    My one does it more than every hour but it can't even manage to save device type icons plus of course their android app uses diffent device icons. One would think it was designed / programmed by two teams with different product specifications.

     

    My latest log.
