How to make the “guest network” work well?
I have a deco network with topology as below

i use X20 for Main Deco and E4 for another deco
ignore "Masjid Belakang" and "R2" units, because im turning it off, in this topology i not use switch or anything, i just connet via LAN port on deco
the connection is like from Internet -> MainDeco(Port 1), MainDeco(Port 2) -> Ruangtengah(Port1), Ruangtengah(Port2) -> R1(port1), R1(port 2) -> R2(port1), R2(port2) -> R3(port1), R3(port2) -> R4(port1)
why guest network just can acces from MainDeco and Ruangtengah ? do I have to provide a switch after the “Main Deco” and connect all Deco to the switch and do VLAN settings?
or is there another way of setting so that the “guest network” can be accessed from all decos?
