TP-Link Deco BE17000 Tri-Band WiFi 7 Mesh System - 8-Stream, 17 Gbps, 200+ Device Connect, 10 Gbps Wired, AI Roaming, Google/Alexa, HomeShield 2-Pack, Deco BE75

I purchased this system because the BGW320-500 modem/router that AT&T provides with their fiber internet didn't provide good enough Wi-Fi coverage, among other issues. I put the main unit near the AT&T router and spread the other two satellite units in the living room and the master bedroom. This meant the three TP-Link units were well distributed throughout my home. Immediately we went from spotty Wi-Fi performance to excellent coverage and speeds everywhere in my house, even the back bedrooms which before had hardly worked at all.The setup is very easy, with great instructions that guide you through the process. The speeds of downloading and uploading doubled right after installation. What is really great is the interface to the units which is easy to use, and was working fine right out of the box, but it provides access to many features that can be tweaked as you wish. The satellite mesh units can be connected via Wi-Fi or ethernet for better speeds. I have them connected via Wi-Fi and it works well. The streaming units (Roku and Apple TV) connected easily and we get great streaming performance to our 4k TVs. All the IoT devices (refrigerator, coffee maker, dishwasher, Apple Pod, Atmos speakers, etc) connect fine and operate flawlessly.It required some work to get the AT&T BGW320-500 into "passthrough mode", as AT&T does not provide the ability to have the unit operate in "bridge mode" which allows all Wi-Fi and other functions to be handled by a better unit like this TP-Link product. I had to do quite a bit of Googling and reading guides and forums where other users had worked out all the settings that need to be adjusted on the AT&T BGW320-500 to get it to work well with this unit (or any unit, for that matter). Luckily there is a robust user's forum on the TP-Link website where a collection of gearheads documented the procedure to get things working well. Once I got that all worked out, I got the full 1 gigabit speed I'm paying for and it operates flawlessly (even after a power outage, it all came back up working fine).My family (and others that have stayed with us over the holiday) have really enjoyed the much better Wi-Fi coverage and speeds this unit has afforded. I have my Synology NAS (running my Plex server) connected via ethernet to this unit, as is my MacBook Pro, because I get better speeds that way (as my 2018 MacBook Pro does not have Wi-Fi 6e capabilities). However, the Wi-Fi speeds to my newer PC laptop (and my wife's newer MacBook Pro) which does have Wi-Fi 6 matches the upload and download speeds of my hardwired ethernet connection to my MacBook Pro. So, if you're looking for better coverage or speeds, I can recommend this product wholeheartedly. It's definitely one of the best mesh router products out there, easy to set up and easy to use.

(**4 month UPDATE at end**)I was concerned that this system may require more technical skills than I have to set up, but I was wrong. I'm 64 years old, just average computer skills, and had these 3 Decos set up in ~15 minutes - and most of that was downloading the app, making your account, passwords, etc.I have Mediacom as my internet provider, and a Hisense router/modem combo. The TP Link Deco was literally 'plug and play', with simple step by step instructions.I had read reviews where you may have to do something to 'bridge' or (unbridge?) your router (to get higher internet speeds I suppose) but I only had to plug one of the TPLink Decos into my modem and that was it.I placed the other two Deco units in other rooms, plugged them in and the 'main' TP unit recognized them. As you connect your devices to the TP Link network the Deco with the best signal automatically picks them up (assuming you have more than 1 Deco unit). On the TP app you can see which Deco unit your device connected to.I had no issues with my existing router/modem or internet provider/service, nothing to change or set, etc.I get around 850 mbps download and ~40 up on my cell when it's on the TP Link wifi network, and everything in my house and all outside cameras all now have a very good to excellent signal (the total area of my house is at least 3,500 sq. ft.). I suppose people with more tech skills than I could make adjustments to their router to get even higher speeds, but the coverage and speeds I get are more than enough for streaming movies, PlayStation games, cameras, and numerous other devices.I got this because I've recently installed a few security floodlight cameras around my house, and had a poor signal on the ones at the rear of the house. Now all cameras have a good signal, and I have a wifi signal in my garage where before I had none.*There's also a "WiFi Toolkit" app that you can download on your phone that allows you to very easily check your wifi signal easily all around your house, so you can use that to determine where to place a camera or, if you are limited on where you can place a camera this app will tell you if your signal is sufficient at that location. That app can save you a lot of time and trouble, to show if your device will have a sufficient signal before you mount or install it. Very handy app.Everything in my house (around 22+ devices - cell phones, iPad, PlayStation, robot vacuums, TVs, Alexa, smart lights, etc.) connected easily to the TP Link wifi. You just have to go to each device’s settings and change its wifi network to the TP Link network.I've only had the system for about two weeks now, but so far, it's been perfect.**4 month Update: I’m happy to say that everything still works great, no issues. Anytime I add (or replace) a device I just choose the TP Network and it connects, no problems. I have several different devices from different manufacturers- Simplisafe alarm, Ring and Tapo floodlight cameras, Kasa and Govee lights/devices, PlayStation, Alexa, Shark, and Roku TV - and everything connects and works great with no problems.
