Hi, we switched to this router from a synology RT2600ac router. (Worst router I've ever owned)  I had previously been using it as an AP to get better coverage in our backyard, but it's not really all that great and I would like to get another tp link product instead. I have tried extenders in the past, they worked great outside in the winter, but they quickly overheat in the Arizona temperatures, and are all but useless from inside.  I'm also hoping to find a solution that doesn't require running an Ethernet cord through the house, as that would mean going into the attic. (not recommended this time of year)  I don't know if it matters, but we have an older home (40-50 yrs?) and the exterior block walls have been filled with foam insulation and are stuccoed. I appreciate any suggestions or advice anyone might have for me.  Thank you!!
