I purchased two identical routers, ARCHER AXE75 (EU) v1.0 and attempting to initialize OneMesh functionality in my home.

Both routers were properly updated (via Tether app) to latest firmware: 1.1.9 Build 20231115 rel.37295(4555)

This is my setup:

I am not IT person, and so far on this journey I was guided by chatgpt as I lack even the basic routing knowledge.

Expectations: 

• as I walk with my portable devices within my home, wifi connection would switch between Router 1 & Router 2 based on proximity or signal strength without usage of 3rd-party apps for switching networks

Quick recap of above image:

• Router 2 is set to AP mode
• SSID & PW are same for both wifi networks generated by both routers
• in Router 1 the OneMesh option is enabled
• in Router 2 there is no OneMesh option in settings at all (perhaps because Router 2 is in AP mode?)

Questions:

• why OneMesh is not working? is there something wrong with my setup?
• does OneMesh not working whenever one of the routers is in AP mode? (please note that I am not interested in theoretical connectivity standards of OneMesh, but rather the OneMesh within the scope of above setup)
• in Tether app when viewing NETWORK MAP > MESH DEVICES there are 0 found devices. whats the issue?
• should SSID & PW generated by both routers be same or different?
• should Router 1 be connected to Router 2 like LAN to WAN instead of LAN to LAN?
• how can I even detect if OneMesh is working at all, or properly?
• should Router 2 be set into 192.168.2.1 instead of 192.168.1.2?

thank you in advance for detailed answer
