I am looking to add one or two mesh satellites to our home which  is 3700 sq ft, one level and

I have Cat 6 wire running from router to location for two satellites. I have also made sure there is AC at each location.

I am looking at the AX7800 the AX6600 and AXE5400. One of the satellites will be on back porch under roof cover will these be OK worst case is some dust and heat. Or should I get the Deco X50-Outdoor PoE. My only concern is the outdoor unit is dual band and not as robust as 7800, 6600 and 5400.

Looking for suggestions. Thanks
