What routers have been successful binding P1P/S?

TP Link Omada EAP650 access points, ER605 router and OC200 controller.

I have a separate hidden 2.4GHz WiFi for my WLED controllers. I switched this to visible, connected the printer, power cycled a couple of times to ensure it connected happily and then rehid the SSID. It’s connected first time, every time after that.
