I have a three level house, 6,000 sq ft., and pretty thick walls. I have an orbi system now and it is not doign the job, so I am looking at Deco, but I am having trouble figuring out the best set up. The modem is at one end of the first floor. I am thinking I would be best served by either the P9 or M5 system, but I'm not sure. For one thing, how does the P9 system deal with thick walls, is is a plugging into the electrical system setup? if so, does it matter if the base unit is on a system of surge surpressors? Alternatively, I am thinking of getting the M5, but with extra units. I was thinking about the base unit, one more at the other end of the first floor, and then one upstairs and one downstairs. Do they sell additional units (single)? Or would it make sense to get the 3 pack and the 2 pack of M5 and put three on the first floor and then one upstairs and one downstairs.
The thee pack plus the two pack of the M5 costs about the same as the three pack of the P9, which do you think would be better for me? Thank you!!
