[NWA130BE] - NTP sync delayed

Maverick87

Hello,

I've an NWA130BE that use an internal NTP server.

As per image, the current datetime is 20/08 @ 11:23AM instead the AP have 19/08 @ 23:23.
The uptime is more or less 3hrs

This is the System log after power up the AP:

My network goes down in the night, and wake up on morning.
The problem is that the AP finishes booting before 192.168.100.1 is available, so NTP effectively fails to sync. The problem is that there don't seem to be any retries for the next 3 hours.

I've collected the information, if you would I'll send on PM.

Thank you

This is when the AP start syncronization:

As you can see the system as "started" at 19/08 20:36 (8:36PM) and the sync was successfully completed at 20/08 02:35AM, so 6 hours after the system start-up.
So, if the NTP don't sync at first time, the system wait 6 hours to retry to sync.
I've collected the logs, as before if you would the log, ask me :)

I blocked the NTP powered off the AP then on it kept time so either you power off your AP longer over night that time does not keep or you changed the time set back to NTP that not up yet for time to be wrong? or maybe the battery in your AP is not good to keep time moving when off?

Hi Peter,
No, I don't think so.

192.168.100.1 is the firewall interface that also acts as an NTP server.

Probably, since when I shut down the infrastructure at night, I turn off everything (including the AP and firewall), the AP finishes booting before the firewall can distribute the precise time.
So the AP probably uses a default time (it's exactly the last time in UTC format — I've shutdown my network on 19/08 10:35PM UTC+2 Rome/Europe, in UTC 8:35PM) when it can't find the NTP server.
The problem is that the firewall then goes up and running, providing the correct time, but the AP doesn't resynchronize.
