WAN is StarLink. WAN DHCP seems to recycle every 2.5 minutes. Lease duration would be issued/controlled by ISP? Or is this an ER7206 issue? WAN on-line detection check is set to 3 minutes. SFP WAN is also in use to a second SL terminal, but doesn't exhibit this issue. This doesn't seem transient. All 168 pages of Event log capture this. Any ideas?

@Clive_A My ISP I use on this router is talk talk who also have a lease time of 15 minutes, please see the dhcp traffic capture from a mirror of the lan port. Don't think there is anything wrong other than the default of having the logging enabled is annoying with such frequent requests.

@RF_Dude Since the last firmware update of my ER605 to 2.2.3 my DHCP lease is on 15 minutes, i.e. the device is trying to get a new IP every 15 minutes.

@CAP-Team I am getting exactly the same issue and it is ever since I updated to 2.2.3

It always was renewing the lease even before you upgraded!. Its just that 2.2.3 now logs it by default so you notice it!, unless you disable the log.
The DHCP lease time is defined by your ISP.
