I am trying to spec a small mesh network using TP-Link hardware, whose requirements are a little different than the prepackaged ones (and I need to keep it reasonably priced).  First let me say that I want the system to have the latest technology - WIFI 6, etc.  It will be located in a rural area.  The house is not overly large and is currently covered with a mediocre, older router; so probably only requires one mesh unit. But I need a second mesh unit outdoors.  We spend a lot of time outside there and we have several WIFI cameras outside that need a strong network connection. I would probably mount it under the roof overhang of a detached garage and use an AC power source for it.  Because the signal would have to pass through a number of walls and running Ethernet cable would be difficult, my thinking is to use an “Outdoor Deco Power Line” mesh unit.  Is there one?  So my system would be a two-pack but one of the mesh units would be an indoor model with “Power Line” and the other one an outdoor model with “Power Line”.  I am pretty sure that TP-Link marketing does not offer that package.  However they do offer a lot of models which quickly confuse me.  So can anyone help me specify such a system using what they do offer, including keeping the cost reasonable?  Thanks.
