My existing router isn't able to allow the S1 to fully cover the 3rd stall of the driveway or the entire length of my sidwalks on my corner lot without losing wifi signal.  I will absolutely have to upgrade to a mesh system for the M1 to cover the full yard.  In searching out mesh system, all of the recommendations are geared toward indoor performance.   What mesh systems has everyone had the best mapping coverage for full yards/long sidewalks?
