Can't ping Printer when Devices are on different AP's

[Rando]

Hello,

I have an RT-AX88U as my main router with two RT-AX92U in a mesh connection. Running the latest stable versions of Merlin on the RT-AX88U and gnuton versions on the RT-AX92U.

The printer is wirelessly connected to the RT-AX88U and my testing devices are wirelessly connected to the RT-AX9U.

All devices of these devices are connected to the same 2.4ghz wireless SSID connection. This is not a Guest Network.

The two devices on the RT-AX92U AP cannot ping the printer on RT-AX88U. If I move one of the devices and connect to the RT-AX88U they can ping and print successfully. They are all on the same 192.168.2.x subnet. The printer has a static IP address in the DHCP IP Pool.

What am I missing?

Thanks in advance!

To confirm, you have the two RT-AX92U configured for AP mode and not AiMesh mode, correct?
If configured for true AP mode, how have you configured the WiFi on all three devices, main router and two AP nodes?
Have you activated WiFi AP (or client) isolation on any of the routers?
Can you ping or access other WiFi devices other than the printer?
Are you running any addon scripts on any of the routers?
What other troubleshooting steps have you tried?

Sorry they are set in AI Mesh mode.

Everything is connected to same subnet. 192.168.2.x

As you can see in the pictures the printer and my 9 pro fold are on same network different mesh AP's.

As you can see I'm unable to ping from my phone to the printer.

Printer is pingable from the ax88u router that it's connected to successfully.

I'm out of ideas.

Why you run GNUton's fork on your AiMesh nodes? Everyone around reports better experience with stock Asuswrt on nodes and even RMerlin himself advised using stock Asuswrt since Asuswrt-Merlin (and fork) adds nothing to proprietary closed source AiMesh.

Thanks, was not aware aimesh issues related to merlin or gnuton's fork. I have moved the AIMESH nodes to ASUS Firmware and have kept my main RT-AX88U on merlin. Will report back how things go after changing them.
