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

I have xfinity, Will this be compatible and work for my 2600 sq ft house or is it overkill.
routers and mesh are independent of internet service providers as long as the cable modem provides you with a LAN output that you can hook up this Mesh into you are good and for that sq ft yes it will be good to have

This is good set, very functional app and easy to configure. The only challenge is, the range. My house is about 3900 Sq. Ft and facing challenges with coverage. Tried multiple different configurations but no luck. I had to install an extra range extender for complete coverage. No reset/downtime, always-on coverage, no other issues so far.

Best Wifi mesh system I have ever used. I work in IT and work from home.

Using total of 4 to cover 4,500 sqft house over 3 levels. (50+ smart devices connected)

Want a rock-solid internet setup?

1. Subscribe to whichever internet service provider is rated best in your area. (I use Xfinity 600mbps/20mbps)
2. Use your own DOCSIS 3.1 cable modem - I recommend https://www.costco.com/netgear-ni...64287.html
3. Use TP-Link Deco M9+ mesh setup - https://www.costco.com/tp-link-de...77095.html
Sums up what I have been doing for past couple of years. Except I would suggest saving some money and simply get a docsis 3.0 modem, which is sufficient for home use and whatever xfinity offers. You won't be able to benefit much v3.1 unless you have like enterprise grade 1-10 Gbps connection.

There is a big benefit. The DOCSIS 3.1 channels are dedicated so you won't be sharing it with D3.0 and older modems. Also the D3.1 channel uses OFDM which is much more robust against noise and more efficient.

square footage can also be 2 floors so it "may" sound gigantic but not really in person Smilie

e.g. you live in a 2 floor house that is 20ft x 40 ft. that'd be 1,600 sqft

I had issues with the range on these. Other than that, they work fine. Ended up just wiring all of them instead of wireless backhaul due to the range issues.

Non expert here needing advice. I bought one, thanks OP. Moving to a house that has cabling directly into garage where there's an in wall modem. Ethernet wall jack in office.

Old Google mesh runs directly from office wall hardwired but connection to other pucks is week so much so signal isn't good enough for streaming, hoping this helps. Any advice to make the most of this would be appreciated? Ex: What is moca and do I need it? Should I connect a puck to a router first? TIA for any help.

Not really the best if you upgraded it to something better…

I recently purchased and installed this unit. Been great so far...but how do I test the mesh speed? So far I only see how to test 'internet speed' which seemingly is consistent w/ what I pay for from my ISP. Is mesh speed a different test in the app (if so I can't find it).

This router runs hot to touch, I fixed it by drill some holes on the top where it slopes to vent. Temp feels only slightly warm to the touch now. Hopefully this will help it last longer. I think most of my previous router died by heat. I believe the design is intentional so it won't last too long.

Netgear mesh is 169.99 and has Wifi 6 but Dual-band, vs this one has no Wifi 6 but is a Tri-band. How come people are way more excited about this one? What am I missing?
