Where to add new M4R in Deco P9 mesh
I have a P9 mesh network (master and 2 slaves) in daisy chain set up. I've just added an M4R for my garage. Hadn't realised the M4 doesn't have PLC (I guess the clue's in the "R" at the end - who knew) as I am setting up a home gym and need wifi.
So the M4 is at the end of the line (ie P9>P9>P9>M4R) and has no PLC and chooses 2.4Ghz from the main unit which is quite close to it (garage is attached to side of house). Two questions:
1. Can I make the M4 select 5Ghz wifi in any way? It's not apparent on the App
2. If I don't get enough bandwidth then am I ok swapping the first P9 in the daisy chain with the M4R? I'd support the M4R in its revised place with ethernet backhaul. Would the configuration be
P9 (master) > M4R (ethernet backhaul to master) > P9 > P9
P9 (master) > M4R
and P9 (master) > P9 > P9?
It probably doesn't matter but I'd like to understand it better. Would swapping the units in the daisy chain give me better coverage in the garage?
