I am using Archer AX72 AX5400

I like to use the Deco 75 pro to extend my network using mesh 

or 

Deco X50

Questions

1. Can it be done using wired mode with a hub/switch as the main connection point?

2. Can it be done with direct connection to the AX72 ports using wired mode

3. Can it be done using wireless Mesh technology as I understand Deco only support Deco products for wireless Mesh

Need some advise

Regards

Raymond
