Weak WiFi, limited management function, overloads easily and drops out frequently - NOT RECOMMENDED!

I usually find TP-Link products to be a decent value, but you should stay away from the DECO line. At first the Deco systems seem ok, but you will need this 3-pack just to cover 2000 sq ft effectively, not 5500 sq foot as advertised. I purchased 3 more to extend coverages, and the processor cannot keep up with the load. I DO NOT RECOMMEND this solution on all but the smallest of properties, with very light usage.
Just google "deco cpu overload" without the quotes and you'll see their horrible tech support stating that "100% cpu load is not an issue, unless it is causing you problems"! Really? 100% cpu load on a network device is the kiss of death - packets are going to get dropped. Try upgrading your firmware. Go to Beta Firmware. Oh, none of that works? We'll get our engineering team to look into it. While your house WiFi is cratering and can't keep up.
My first sign of trouble was when a device less than 20' away could not pick up a WiFi signal from the main deco. It did have to go through one exterior stucco wall. Well, it won't go through more than one typical drywall interior wall very effectively either. So yeah, you need one in practically every other room.
Want to see which devices are attached to a particular Deco node? No such luck - you'll have to look at the list of each connected device one by one, click on it, and see which Deco it is tied to. Why would you care? Well if one Deco goes offline and distant devices connect to another, they often stay that way even when the closer device is back, so they are running on a very weak signal when the stronger one comes back. No signal strength tuning is possible. Want to set the device manually to the nearest Deco? No way. The only work-around is to make sure all your network Deco's are up, then go power cycle the devices you hope to steer to the now closest operating Deco.
Want to just set it up and forget it? For a small home with an open floorplan and very very few devices it might work. Your endpoint devices will add up quickly: a couple of TV's? Desktop computer? Couple of Laptops? A few tablets? Smartphones for everyone? Alexa? Google Home devices? Wifi Thermostat Before you know it, most people have 10 devices real easily, and that is going to suck the life out of your Deco, and you as well trying to reset them.
Why do they have so many models? There are seriously 8 to 10 different Deco models, and this mesh line is only maybe 3 years old. Some have almost no discernable published technical spec differences. Some do have newer WiFi bands, but the line appears to be intentionally confusing.
Save your sanity - buy something else. Google for issues, because store ratings don't tell the whole story.
