A few months ago, I reconfigured my home network with Omada and set up two access points: EAP225 Outdoor and EAP245. I have three Wi-Fi SSIDs enabled: Home, IoT, and Guest.

Recently, I’ve been facing an intermittent issue where some cameras and IoT devices become inaccessible. The issue occurs randomly, and while the devices appear in the client list of the AP, any attempt to ping them results in “Destination unreachable.”

After extensive debugging, I’ve identified the problem: it happens when devices are connected to the EAP225 Outdoor access point. When I lock these devices to the EAP245, the issue does not occur.
 

Here’s what I’ve tried so far to resolve this:

1. Resetting the EAP225 Outdoor.
2. Replacing the Ethernet cable.
3. Using a shorter cable.
4. Testing the access point on different devices.

Any clues?
