coz unifi got two kind: one fiber then VDSL...

they want to make thing easy so use same router always... jus the modem is different..(fiber or vdsl) .

if all house using fiber maybe tm will use single box also...
but coz high rise and like that need vdsl.. so need another kind

using router as fixed device always same... and hypptv connected to router.. so config on router is fixed on all unifi

the only difference is modem depend on technology used. simple right?
