ZenWiFi Pro ET12 - The node ends up yellow with no connected devices after firmware upgrade

[WebMaximus]

I could really need some help here because I'm starting to pull my hair out trying to figure out what is going on here.

I have a pair of ZenWiFi Pro ET12 routers. Yesterday, I was informed via the Android Asus Router app there was a new firmware available (3.0.0.6.102_36597). After upgrading both routers to this new firmware version, the router acting as the node ends up showing yellow rather than white and no devices connect to it.

I've tried to pull the power, reset first the router acting as node to factory default settings and then both routers when just resetting the node didn't help. No matter what I do it seems, I end up in the same situation after setting everything up again. With the router showing white color and the node yellow with no clients connecting to it.

What on earth happened here and what can I do to make my setup work normally again?

With big thanks in advance for your assistance!

Same here, led is yellow. I too could only reset by the mentioned wps method. Annoying.

Same issue after installing firmware version 3.0.0.6.102_36597. Steady white on router, steady yellow on node with web GUI showing "great" connection with 6Ghz backhaul.  Unplugged the node from current spot and moved node 3 feet from router and still showed yellow on node which leads me to think the firmware is the issue.  To confirm, I rolled back to the previous firmware and both show steady white.  Tech support was not able to provide a solution.  Hopefully, they will get this fixed soon.

Sorry, I don't intend to start messing around with this again now when I finally got it working. I already spent enough time solving the issue.

Surely you must be able to repro the issue on your side without help from your customers based on how multiple people have reported the same issue in here.

Agree. Been struggling since Sunday. This morning I rolled back 1 node to 3.0.0.4, since impossible to join the mesh until I did a hard reset with wps button. Result: led solid white, all connections fine. I leave it for now!
