@terziyski Great advice. I save existing configuration for AP mode. When I converted to router mode, I got OneMesh option visible. The RE605X is now working fine as range extender in OneMesh mode...

I got another reply from TP-Link. The RE605X supports OneMesh, but doesn't support EasyMesh. OneMesh: https://www.tp-link.com/us/onemesh/product-list/#range-extenders EasyMesh:...

@terziyski Currently my AX20 is in bridge mode or AP mode. Is this the reason I am unable to see OneMesh configuration area when I log into its management WebUI?

How to confirm if I can connect RE605X with my Archer AX20 v1.0 through EasyMesh or OneMesh? Please advise.
