Setting up wifi at home

[car10002]

Hi everyone

Eventually want to upgrade to the ax wifi from the ac and also want the mesh wifi that covers whole property.

Have the following routers in mind and wondered which is best

1. ASUS rt-ax82u
2. ASUS rt-ax88u
3. ASUS rt-ax92u
4. TP-link archer ax73 with tp-link re605x extenders
5. TP-link archer ax50 with tp-link re605x extenders
6. TP-link archer ax90 with tp-link re605x extenders

If using ASUS what listed model would you use at the main and extension spots for mesh.

Also if you already got a wifi network at home wether it be seperate modem and router or modem/wifi router In one is it possible to plug another router into the modem/router to have a completely seperate wifi network just for you wether or not you have 2 mesh wifi systems

Thanks
