The best mesh router I have ever owned. Worked flawlessly until I got super greedy and spent 2K on wiring the whole home and installing TP Link EAP-660HD AP (TP Link earned my trust via M9 Plus and I didn't even consider Unifi or Zyxel or anything else).

BTW, this is much faster than crappy Google mesh system, including the newest one (I used nest mesh for few months before getting M9 Plus). Two of my extended family are still using M9 Plus and it still work flawless for them.

You are expected to get around 550 to 600 Mbps on the main router (YMMV based on your wireless interference). If you wire the satellites they will also get you same sped. Otherwise speed will be based on wireless link speed. And M9 plus has tri band. So even wireless linking works flawlessly. I was pulling close to 400Mbps in my office and on very far end of the house I was pulling about 250Mbps.

I have a 3950 square foot house. I have a 4 pack of the gen 1 Google wifi. I have computers, TVs, kids tablets, smart switches and outlets and bulbs galore. There's nothing crappy about Google mesh. I do prefer it had remained in its own app instead of being smashed into the Home app. I did install the wiring myself to each one (modem->router->switch->satellite pucks). I've never had a speed issue or failure or any problems.

Also replaced Google Wifi 1st gen with these. Huge upgrade. These routers tend to get hot underneath so best to elevate them a bit with stick-on tabs or find another solution to let them breathe easier

Seems to be priced accordingly.

I flip them over so the vent holes face up. Been great for over a year.

I tried setting this up via wired backhaul but the guest network would not work, despite following instructions in the app how to properly configure with a unmanaged switch. On wireless backhaul it was fine but obviously it was slightly slower (200/10 internet connection managed to get 100-150 down on the nodes). I ended up returning and switching back to AC68U AiMesh setup with wired backhaul for the speed and guest network (I'm paranoid and put all my IoT on the isolated guest network)

Great price it can't do 802.11 ax so it's a little older in technology than others out on market. If looking for speed this isn't what will work best. But I bet it works great with meshing and stability.

I have mine in wireless backhaul and get consistent 250 mbps on wireless in a 2,000 sq ft home. The malware / parental control is lifetime supposedly. On the newer deco models you have to pay monthly for those features. Very reliable and no issues at all for 20 devices.

I had a terrible experience with TP-LINK recently. My 3-months-old ac1750 started dropping internet connection every few minutes and completely stopped working one week later. It is a pretty common issue of this router. Contacted their CS, they just tried to use all kinds of excuses to blame ISP instead of sending me a replacement. Although spectrum has a really bad reputation on internet stability, it is not spectrum's problem this time because I have a spare router and works just fine. They let me pay for the shipping and sent back a refurbished router. I am very disappointed about their support and warranty. This deal is from Costco, so you can always return it to Costco. But I don't recommend to buy TP-Link product from other retailers because their warranty is a joke!

Best mesh kit out there and I do IT. I suggest this for all my friends and non business clients because it's simple out of the box and very stable. I run pfsense and unfi u6-or AP myself but that's extreme for most ppl. cisco meraki at work and Aruba at some of my clients so i can compare to many systems.

Google WiFi works but deco m9 plus is faster, tri band and also works flawlessly. Google WiFi never gave me the speed deco m9 plus gave.

To save many of you headaches, dont worry about wired backhaul unless you have some massive sized files you need to transfer simultaneously.

Worry more about optimal placement of the units more so than anything. Most home users won't saturate the wireless connectivity backhaul with day to day use.

For others with large file transfers that dont want to spend a fortune nor the time to create a backbone in their home QoS is your friend.

The last use case is power users that will saturate the wifi link speed and whom constantly move files of 250mb in size or greater across their home network.

Not trying to make anyone feel any sort of way but i wanted to make clear for 95% of users reading these threads about all this wireless backhaul stuff, it is a niche use case and isnt a requirement.

Running this setup for about a year with wired backhaul and I have to say the outside range is disappointing. So much so that I am looking for alternatives before spring. Inside the house the speed is good and consistent but outside it's range isn't as good as others I have had. 3000 square feet plus a basement one on every floor.

My only complaint is that you cannot set WiFi channel.
