What do we have in the box?

  • 3 TPLink DECO M9 Plus devices
  • Cable RJ-45
  • 3 power supplies
  • User Manual

It's time to get up and running and set up:

Before starting the DECO M9 Plus Mesh for the first time, follow these steps:
1. disconnect the power cord from the modem
2. connect the Ethernet cable to the DECO unit
3. connect the Ethernet cable to the modem
4. connect the power cord to the DECO unit
Connect the power cord to the modem

Once the units are ready, let's move on to setting up the TPLink HomeCare system:

Download and install the DECO app -> Register/Login -> "More" -> QoS -> "Edit" -> Total unit throughput (you can set the values manually using the sliders or from the test options) -> "Save" -> Select one of the given categories such as Standard, Streaming or Games etc. (by selecting "Other", you can set this manually -> "Save"

Now it's time for configuration:

Log in/register in the app -> Select a unit -> Confirm the previously performed steps -> Turn on WiFi / Bluetooth in your unit -> Select the location of your unit (kitchen, living room etc.) -> Set WiFi network name and password -> Wait for the network to be created and Done!

Now let's move on to setting parental controls:

We open the DECO app and click the "Parental Control" icon -> We add a new profile and create a name -> We continue with the instructions and select the level of content filtering -> We enable the "Malicious Content Filter" in the "Options" of the Antivirus so that the parental control function can function fully smoothly -> We set the usage time on the child's profile -> We add the prepared profile and Done!

It is worth mentioning that this home WiFi system has a built-in antivirus, which will easily detect dangerous sites, protect us from attacks, and if the device is infected, it will move it to the quarantine so that your sensitive data will not be stolen.

Let's compare our tests with the manufacturer's information

Let's now take a peek at our tests and the throughput gained by each TPLink router. We'll also check to see if there were any WiFi dead zones in the building. We set up the TPLink DECO router on the first floor in the eastern and western parts of the house, and a third router on the first floor in the southern part.

The network that the DECO units build operates on three bands, which are distributed among the available devices to ensure smooth network operation. If you need more coverage, you have MU-MIMO at your disposal in addition to the three bands. The 4 × 4 MU-MIMO technology is extremely useful where users download more data than they upload. The technology helps increase overall network performance and supports all available channel widths.

The manufacturer claims a wireless transmission rate of 1.5 Gbps, which would work perfectly with a fiber optic network.

To summarize our testing:

We had a few surprises here. We thought the TPLink DECO M9 model would complement the previous version, more of an upgration of it, but we were a little disappointed.
However, on the plus side, the application is quite intuitive and easy to use. Also, the setup is not problematic. The minimalist design means you can set it up anywhere in the house, but you have to remember to connect it with a cable to the modem.

Back to the more technical stuff. Admittedly, the model we have here is AC2200, but inside we didn't find a 5 GHz module that will provide via MIMO the AC 1800 mode. We found here only 2 modules with AC900 (867 Mb/s) and a 2.4 GHz 400 Mb/s module as a complement.
Unfortunately the coverage was quite poor. We couldn't even get throughput up to 600 Mbps - the Mesh ends transmit weaker than the main base.
We were very surprised by the poor speed test results - the highest throughput we got was 552Mbps. The technical specification states 4 × 4 MU-MIMO, but most likely we are dealing with 2 x (2 × 2 MU-MIMO) here. Generally, the coverage was available in every room, but in much smaller values than it should be.
