Solid product - probably more than I needed 4/29/2020 4:08:11 PM

Pros: -Fast
-Good coverage
-Easy to install
-App makes things convenient

Overall Review: Very quick and easy installation using the Deco app. Clean and clear UI with enough features, like included Antivirus. Covers my house very well at 2,800 sq. f (even at 4 floors). I was unsure due to the number of floors if the coverage may be slow in some areas, which is why I went with the M9 Plus even though my internet speed doesn't even go up to the supported 400 Mbps. Seems as though it wasn't even necessary. Strong signal and speeds all over the house. Would recommend.

Good AP but missing basic features 7/30/2019 3:38:49 AM

Pros: Strong signal
No drop
Easy installation

Cons: I have this behind a MikroTik router.

In AP mode you can’t tag the guest WIFI with a VLAN id making it impossible to isolate guest traffic. That’s very bad design, majority of IT people will use this product in AP mode, we don’t need another router.

No SNMP for remote monitoring.

I hope they fixe all that in FW update.

Manufacturer Response:

Thank you for your review. When the Deco works in Access Point mode, it does not have NAT functionality, so its gateway features (Antivirus, Parental Controls, QoS, IPv4 and DHCP server etc.) will no longer be available on the Deco app. For more information regarding this topic, please see our FAQ here:

The Deco M5 is designed to provide convenient, mesh WiFi for most home networking environments. The features you have specified are more commonly found in enterprise level Access Points, which we also offer. Nevertheless, we appreciate your feedback regarding features you would like to see added to the Deco Mesh WiFi system, and we'll gladly share it with the appropriate team.

Our Support Team is always happy to answer any questions you might have about our products. Please feel free to e-mail and we'll gladly have a Support Agent follow up with you directly.

Thank you,

Wow! I love these! 5/24/2019 10:13:57 AM

Pros: Recently, I was using an older TP Link dual band router. All of my devices in my home are connected to the WiFi. The upstairs desktop was having trouble with drop outs, lost connections, and slow speed. Now, this has been a good router. But sitting beside it I could only get 60 Mbps throughput. After installing the M9 plus, I could get 200 Mbps on my tablet! I installed the dual unit system which covers 4000 sq. ft. In our 1800 sq. ft. house. I’m looking like the networking guru! Installation was a breeze. I’ve installed my share of routers over the years and some have been a bugger. I’m feeling like this was the best purchase all year! I’ve been up and running about a month and have no complaints! I highly recommend this!

Cons: They aren’t free! But, they were cheaper at Newegg than Amzzzzz.

Overall Review: Highly recommend this product!

Update from previous Review 2/10/2019 1:07:29 PM

Pros: Easy set up
Super fast speeds
One wireless id

Cons: Can’t see other devices on the separate nodes
Some artifacts while streaming

Overall Review: The guy that did the second review is talking about the M-5 not M-9, so disregard his comments.
Update 1/27/2019 - Dropped from 5 stars to 4. I have had this for about 3 weeks now and discovered an issue. Even though my internet speeds are maxed out throughout the house , which is why this is still at 4 stars, the Deco Node does not see devices on the other Deco nodes. Basically I am unable to stream content from my PC which is hooked up to the Primary Deco node via ethernet to the secondary deco that is wirelessly connected to my QLED Samsung TV.
My workaround - I hooked my DIR 890 back up to the modem, and then connected the Deco to an ethernet port on the DIR 890. I have one wireless ID for the 890 that I use just for my TV's, and when I want to stream from my phone I hook up to that wireless network. My PC which has ethernet into the DIR 890 can stream without an issue.
One other issue I have seen with the Deco and streaming Hulu on the TV is an increase in artifacts during playback of recorded shows. Now that I am back up on the DIR 890 I will monitor to see the artifacts decrease.
Overall the family is still happy with Deco, they have not complained about dropped wifi, or issues connecting. The coverage and speed remained the same even when I connected through my Dlink 890, but my intention was to remove that router, and now I had to bring it back in to make the Deco work.

Manufacturer Response:
Hi Mike,

Thank you for sharing your experience with our product. We appreciate your feedback; however the prices you referenced on those retailers are for single packs (1-Pack), containing only one Deco M9 unit. The Deco M9 Plus Mesh WiFi System you reviewed is a 2-Pack, containing two Deco M9 units.

Depending on the size of your home, the 2-Pack may provide more adequate WiFi coverage and performance. If you are ever uncertain about our products or their features, please feel free to e-mail and we will be more than happy to help you.

Thank you,
TP-Link Support
