I am wondering if a tp-link plug-in range extender RE3xx is the same as a slave Deco M4/X4 but without the possibility of ethernet backhaul.
Is the only difference perhaps that there is no possibility of further piggybacking on the extender to add a mesh component.
In other words if a mesh component (another deco say) is added in the range of the extender but out of range of the main Deco it will not work.
As a matter of policy, would it be correct to add Decos only when you know that you need piggybacking.
So for example in a long straight house use: RE - Deco(slave) - Deco(main) - Deco(slave) - RE
Will this work the same as: Deco(slave) - Deco(slave) - Deco(main) - Deco(slave) - Deco(slave)
Or are REs so versatile that is it actually even possible to piggy back a mesh network across REs?
