BUG: Router reboot causes DHCP errors
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
When the ER605 router is rebooted clients with static IP reservations receive incorrect IP addresses from the default IP pool.
Basic stuff this, do NOT issue IP addresses via DHCP until the static list has been loaded. I suspect this happens during the provisioning cycle when the router is rebooted, just carless testing/programming.
Fix it.

What's the current firmware version of your ER605?
Have you tried the latest beta firmware 1.2.2 Build 20230208 provided in this solution post?

Thank you for providing the device info. It seems that the issue is reproducible with a router reboot. How many clients are configured with DHCP Reservation? Would all of the clients configured with DHCP reservation obtain random IP addresses instead of the reserved IP? Or the issue only exists with some certain clients?
To better assist you, I've created a support ticket via your registered email address, and escalated it to our support engineer to look into the issue. The ticket ID is TKID230236078, please check your email box and ensure the support email is well received. Thanks!

All of my clients (70+) have DHCP reservations. I have a 1 hour DHCP lease time and it looks like it's is only those clients whose lease needs to be renewed during a router reboot/adopt cycle (about 5 mins) that get an incorrect IP
My guess is that the DHCP addresses are being handed out as soon as the router is rebooted but before it is adopted by the controller and the DHCP reservations list is transferred.
Out of 70 clients, 20 were given 'incorrect/IP Pool' addresses during the reboot.
