Gateway router Vigor 2830 is 192.168.10.1

AP Router Vigor 2830 as Switch Router is 192.168.10.2

In order to set up schedules on the Switch router I need to have the time correct. I have the switch router lan 1 connected to a lan of the Gateway router. DHCP is disabled on the switch.

Am I correct in thinking that the NTP time will only update if the second (switch) router connects via WAN port? How can I get round this? Any time the second router is re-booted, it of course, looses the correct time.

I'd imagine the routers make an internet request for time (NTP), so as long as there is a valid connection is should be fine. In my experience, it can take the router a while to update the time (I assume it tries to get the time before the connection is established and then goes into a wait loop before trying again).

My AP902 gets its time from pool.ntp.org and it's connected to the router via a LAN port so I don't see why your AP router shouldn't do the same, unless it's internally configured to only get it via WAN for some reason?

You're calling it a "Switch router" so are you using it as a switch only and no routing / no WAN ports ?

Correct. It's an AP only.

In that case once the "switch" is rebooted, it should pick up the time automatically via its LAN connection (assuming it has a valid network config), although I have to confess to never testing that.
