IoT devices constantly disconnecting
I’ve had the same network setup for a few years, but it seems like since moving last year, most of my IoT devices won’t stay connected to the network (Ecobee, cameras, door lock, printer). When I reboot the access points, they’ll reconnect for ~1-6 hours before dropping again. I have the same ISP and everything else is the same pre- and post-move. Other devices are perfectly fine, like computers, phones, and Apple TVs.
I did a lot of research and tried everything I came across, but nothing has helped and I’m at a loss. Am I missing something? Could the access points be defective?
Setup: Omada router, software controller, EAP670, EAP610
Things I’ve tried:
-Created a separate network with only 2.4 enabled for the IoT devices
-Confirmed roaming was disabled
-Confirmed MLO was disabled
-Always on the latest firmware
-Rebooted and reconnected the IoT devices a lot
-Tried locking the devices to a specific access point
-Tried using just one access point
-Changed channels and tried auto
-Assigned static IP addresses
