In Australia - my house is quite long (13.5m x 24.5m)
My house works out at 3500 square feet. I currently have the modem & router at the front of the house & wifi extender about half way down the house to cover the kids bedrooms at the other end of the house.... works fine, but its about 5 years old & we have a lot of devices, smart Tv, PS4, etc...
Would the 2 mesh system (meant to cover 3000 square feet) be enough or should I go to the 3?
I'm a fan of going a bit overkill when it comes to wifi. But the benefit to orbi is that you can add in satellites as needed if you need more/better coverage.
And its tough for us to tell 100% what'll work because many things can impact wireless such as how many walls there are, what the walls are made of, hvac/plumbing within walls, etc. its why I usually recommend going a little to much versus not enough when it comes to networking.
