wired to wired connectivity issues on ZenWifi XT9

[jessev]

Product: ASUS ZenWiFi XT9 AX7800 Tri-Band WiFi6 Mesh WiFiSystem (2Pack) (https://www.amazon.com/dp/B0BHL6PXQT)

Firmware version: 3.0.0.4.388_24709

I have a two nodes using ethernet backhaul. 1 computer wired directly to one node and another computer wired directly to the other node but are unable to route between them.

I have noticed that disabling the guest wifi network seems to fix the issue. Is there any way to keep the connectivity between wired ports across nodes AND run a guest network?

Hello, I'm using wireless backhaul and I have a guest network and it works. I did have to reset the whole wifi after upgrading the firmware, and then sometimes I have to do a simple reset, but for now it seems stable.
