I am trying to connect my PS Portal to the specific Deco unit that my PS5 is plugged into. However, I have three S4 units and one M4 unit in my mesh, and only the M4 is capable of setting a connection

I think I need to upgrade my S4 mesh to something higher spec that will allow me to set a preferred unit for my PS Portal to connect to. Can anyone recommend the cheapest set of Deco units that will a
