Every 2 days at around 22:00 WAN gets reconnected (Internet stops working for a short time) and I get those lines in general log.
I am using RT-AC87U with Merlin firmware 380.59_beta2. WAN lease time is 4 days.
I tried other firmware versions (Merlin and Asus).

WAN Connection Type: Automatic IP.
DHCP query frequency: Aggressive Mode.


I appreciate any help that you can provide.

Anyone?

Flash the 380.59 final and do a full reset to factory defaults followed by a minimal and manual configuration of the router to secure it and connect to your ISP.

You may also want to turn off all network equipment after having performed the above and physically unplug all devices from the AC power too for 30 minutes to an hour or more.

Then,

Plug in the modem (wait 5 minutes).
Plug in the router (wait 5 minutes).
Plug in any switches you may have.
Turn on any wired devices (computers, NAS, etc.).
Turn on your wireless clients.


Be wary of using the very latest Asus firmware as it may prevent you from flashing other firmware to test with.

I was getting hit by this error several times a day after a recent firmware upgrade. Once I changed the DHCP query frequency -> Normal Mode, the errors went away. The default for me was Aggressive Mode prior.

I am using RT-AC87U with Merlin firmware 380.59_beta2. WAN lease time is 4 days.

It is standard practice for clients to attempt to renew their leases once half the lease interval has expired.
