The first gen Google wifi 3 pack is on sale at the Google Store for $139 right now. That's an outstanding value. Easy to set up and use. If you can use ethernet backhaul you will get excellent performance. That's what I've done. Some of mine runs up through the attic, some runs through the utility room in the basement and through the floor joists. I've used a pair of small switches to make it easy to "hard-wire" my most critical devices/high usage devices. If ethernet is not an option, then MOCA may be an option for backhaul. None of this is terribly complicated, it just takes a little time to learn the basics and get accustomed to some measurements. The nice thing about the Google setup is how well it integrates with Google Home. I still prefer to run some of the tests on the old Google WiFi app which is no longer distributed.
