I current have a 3x Deco system with 2x M9 units and 1x M5 unit. Currently I have the in the following setup:
Fibre ONT -- M9 (Main) -> M9 -> M5
Due to the way the cabling is re-done at my house, I want to change the order now so that the chain will (physically look like):
Fibre ONT -- M5 -- M9 -> M9
With this option, is it possible to still run the 2nd Deco in chain (e.g. the M9) as the 'main deco' despte the fact that the M5 will now sit closest to the ONT? Or is the only option now to run the M5 as the new main as this is the unit that is connected to the WAN source?
