myQ Garage Opener "Offline" on ZenWiFi ET9 Guest Network

[sagarr]

I’m having a specific issue with my myQ Garage Door Opener and my Asus Zenwifi Et9 AiMesh system. I have a two-node setup with an Ethernet backhaul between them.


My garage opener is physically much closer to Node 2 (signal strength is a strong -40dBm). However, when it connects to Node 2's guest network, it shows as "Offline" in the myQ app and cannot reach the internet.

Strangely, if it connects to Node 1 (the main router), it works perfectly fine, even though the signal is much weaker (-70dBm).

The Setup:

• Hardware: 2x ASUS ZenWiFi ET9
• Backhaul: Ethernet cable connecting Node 1 (Main) and Node 2.
• Network: Dedicated 2.4 GHz Guest Network for IoT devices.
• Authentication mode : WPA/WPA2
• Status: Node 2 shows "Great" connection to Node 1 in the app.

Visual Diagram of the Issue:


What I've tried:

• Rebooting both nodes.
• Verifying that the myQ is reachable from the app (online) when forced to Node 1.
• Use many other IoT devices (google home, tplink bulb and switches) connected to node2 and the same 2.4ghz guest network. They work fine.

It seems like Node 2 is broadcasting the Guest SSID but isn't actually routing the traffic to the internet over the ethernet backhaul only for 1 device. Has anyone encountered this "Guest Network Black Hole" on secondary ZenWiFi nodes? Is there a specific sync setting I'm missing?

I have a MyQ opener. It is on a guest WIFI and I have seen the device connect to either the node or router. Use just WPA2-Personal, 20 MHz only on the 2.4 GHz, Do not enable Ethernet Backhaul in the AiMesh settings but Auto (I have better success with Auto). Also use a simple guest network SSID of no more than 8 alpha/numeric characters but no special characters or spaces. Same with the WIFI password for the guest network.

Might be worth trying to enable access intranet ? It might be isolating access that the device needs to phone home to the App? Just a guess.

One of these depending on your GN implementation. Enable access to your main network. Of course it will do it for all devices, but maybe your other ones don’t need access?
