I have an Archer VX1800v running "0.14.0 2.0.0 v6092.0 Build 250417 Rel.24761n" (what kind of version number is this???) as my main router and a RE505x V2 running firmware 1.2.0 Build 20250815 Rel. 43944. Various places on the web suggest that both these devices support ethernet backhaul for EasyMesh, but I can't get it to work; in fact, I can't even get it to work wirelessly - the VX1800v just doesn't "see" the RE505x at all - on the VX1800v if I go to "Add Mesh Device" there are options "Add By Scanning(Recommend)" and "Add By Pressing WPS Button"; I've tried both and neither work.

Before attempting to set up EasyMesh, I did alter a fair few settings on the VX1800v - am I just going to have to reset that to factory as well, or are there any settings in particular that are known to cause EasyMesh to not work?
