Deco M5 Review

TP-LINK Deco M5 is a mid-range wireless mesh system from TP-LINK. It provides wide wireless coverage for houses like double storey or bigger.

It is very easy to setup as it can be configured within TP-Link Deco App.

It is one of the popular, if not, the most popular mesh Wi-Fi system in the market currently.

In contrast to its competitors, it actually comes in the higher specification – AC1300 – instead of AC1200 which is what most mesh WiFi systems that are currently offering.

Ever since we carried this product, we’ve sold a couple of hundreds of them.

Today we will be doing an in-depth review of why Deco M5 is so popular as a mesh WiFi system among the end-users.

Mesh WiFi Designed To Maximize WiFi Coverage

If you are looking for super high-end performance routers such as TP-LINK C5400 or TP-LINK C5400X that comes with advanced features, then Deco M5 isn’t for you.

However, if you’re are looking to solve your coverage issue, then getting a Mesh Wi-Fi system would most likely solve your issue.

Deco M5 can provide coverage up to 5,500 sq. ft, in layman’s term, it is capable of supporting up to a three-story house with no issue.

In any case, where you want to extend your Wi-Fi coverage, you can always add on additional units for better coverage.

Deco M5 WiFi Coverage

As Deco M5 was designed to connect up to 100 devices while maximizing coverage, you will be able to connect all your smart devices such as Smart Switches, Smart TVs, Smart Lightbulbs and many more.

It is also compatible with IFTTT and Amazon Alexa which you can use to configure your smart devices.

In a direct comparison to a router and Wi-Fi extender combo, using mesh wifi system actually provides you a faster and stable connection throughout your house.

Compatible with UNIFI, Maxis & TIME Fibre

TP-LINK Deco M5 is compatible with UNIFI, TIME Fibre & Maxis Fibre.

It also supports HyppTV where you can enable the IPTV function within the TP-LINK Deco App.

While you are setting up your Deco M5, make sure to tick VLAN and select UNIFI profile in the app.

For Maxis and ASTRO VOIP, you will need to setup Deco M5 as Access Point to use them.

Suitable for Big Houses And 500Mbps Plan

Deco M5 is a good fit if you are staying in a bigger house like double-story house as it was designed to solve Wi-Fi coverage issue.

With that being said, you can also use it on a single-story house with a 2 Units of Deco M5.

It’s just that you will have wider options to choose from as upgrading router may be an alternative choice.

We recommend using Deco M5 especially if you are on a UNIFI 500Mbps plan as it comes with AC1300 specifications.

Unboxing Deco M5 – What’s Inside

Deco M5 3 Packs

Here is what you’ll get in the box:

  • Quick Installation Guide
  • 1 RG45 Ethernet Cable
  • 3 UK Pin Power Plug
  • 3 Units of Deco M5

Key Specifications & Benefits of Deco M5

Deco M5 comes with a Quad-Core CPU. It is a dual-band AC1300 model that is capable of supporting 400Mbps on 2.4Ghz and 867Mbps on 5Ghz.

As this is a mesh wifi system, you won’t need to manually switch between the bands as Deco M5 will automatically connect you to the best band based on your distance.

TP-LINK actually did a well-thought user design on two key areas:

Compact Yet Functional Design

Deco M5 Compact Size

Each of these nodes come with 4 internal antennas. It is a very stylish looking compact device that can fit within your palm.

The height is roughly one-inch and we have to say it is a well-thought design.

As it is very compact in nature, you can pretty much place this anywhere as it isn’t as bulky as other brands in the market.


Deco M5 Gigabit Port

Unless you have some basic understanding on Networking ports (WAN port & LAN port), chances are you will plug your ethernet cable into the wrong port.

With the Deco M5, you can actually use both Gigabit ports interchangeably without worries.

Most end-users are expecting a plug and play design (with very little room for error), and this user design really helps in that.

TP-LINK HomeCare – Advanced Protection & Network Control

TP-Link HomeCare

TP-LINK Deco M5 comes with TP-LINK HomeCare which offers extensive parental control, quality of service and network-level protection.

Instead of the traditional anti-virus which scans and cleanse the device, TP-LINK HomeCare acts as a home network security filter that protects all devices on your network.

You will also be able to set Internet filters to prevent your kids from browsing certain sites, even their connectivity time.

Read more about it here.


Gone are the days where you need to be stuck in one place for the best Facetime calls.

With Deco M5, you can experience a seamless internet roaming.

By seamless roaming, we mean that you will be able to do live call through Whatsapp, Wechat, Skype or Facetime while moving between floors and rooms without being restricted to a place with “best Wi-Fi signal” or “best Internet”.

With TP-LINK adaptive routing technology, you will always be connected to the nearest Deco M5 for the best speed and coverage, and with that, you can move around without worrying if your call quality would drop.

Say goodbye to manually change SSIDs when you are moving around!

How To Install & Setup Deco M5

Before we proceed with the installation, make sure you download the TP-LINK Deco App.

You can either scan it on your guide or just head to Play Store of Apple Store to download.

You will also need your PPPoE user ID and password to configure the device.

Download TP LINK Deco App

Next, setup your Deco M5 by connecting the ethernet cable to your modem, once your device is powered up you can proceed with the configuration.

Connect Your Deco M5 To Router or Modem

It’s a pretty straightforward process with the TP-LINK Deco App, you will need to:

  • Select the Deco M5 within the app
  • Select your Internet Connection Type
    • For router mode, make sure to select PPPoE
    • For access point mode, make sure to select Dynamic IP

Deco M5 Select UNIFI & VLAN 5000

To setup for UNIFI, make sure you tick VLAN and select the UNIFI profile.

Deco M5 LED Status

TP-Link really does a good job with the in-app instructions. It even came with FAQs to help you diagnose a situation.

They included these LED statuses to explain and manage your expectations, you can even refer to their placement guide on where to place your nodes.

Settings within TP-LINK Deco App

Amazon & IFTTT Settings

Deco M5 - IFTTT and Alexa

Once you’ve configured your Deco M5 properly, make sure to take some time to browse through the extensive features within the app.

If you own multiple smart devices, make sure to check out the IFTTT setting to set up the commands.

WiFi Settings

Deco M5 - Shake & Share

You can turn on and off your 2.4Ghz, 5Ghz and guest network on this interface.

Both 2.4 Ghz and 5 Ghz are enabled by default in this interface.

One cool thing about this is the shake and share – instead of the typical scenario where you spell out the password, you can shake and share them to your guests directly. How convenient is that?

Parental Control

TP-Link HomeCare Parental Control

What’s really cool about this is TP-Link allows you to customize based on profile.

In other words, you can create different profiles for different family members ranging from child to adult.

With that, you can basically filter out websites that aren’t healthy or even beneficial to them.

Not only that, but you can also set up time limits based on weekday and weekend.

You can even block a person’s Internet access or bedtime, provided you want them to sleep earlier.

I guess that will solve most parenting headaches, then.


TP-Link HomeCare Antivirus

Unlike most antivirus works on the device level, TP-Link HomeCare actually protects you on a network level.

Powered by Trend Micro, Deco M5 offers a three years complimentary subscription (yes with no additional fees), upon expiry you will still be able to use those features, except that the anti-virus database is no longer updated.

With this anti-virus, it protects you from hackers, intruders, and ransomware, it can also detect the infected device.

For example, if your laptop were infected and you didn’t aware, you weren’t aware of it, TP-Link HomeCare will protect the network immediately when the laptop gets connected.

Quality of Service

TP-Link HomeCare Quality of Service

This section basically allows you to set up priority based on your activities preference.

For example, if there are a lot of gamers within the house, then you may set it to priority gaming. Likewise, the same goes for streaming, surfing, and chatting.

To take it a step further, you can even customize your QoS based on your activity preference level down to the level of prioritizing device.

WiFi Speed & Performance

We are running tests on a UNIFI 300Mbps Plan which is slightly underpowered for Deco M5.

All speed test will be done using OOKLA’s app on a Samsung Note 9.

We will be testing in 3 separate locations:

  • 1st floor – where our main Deco M5 is connected
  • 2nd floor – master bedroom
  • 2nd floor – mini living hall

First Test Result [with 2.4Ghz on]

LocationFloorDownload SpeedUpload Speed
Living Hall1st Floor291Mbps53Mbps
Master Bedroom2nd Floor89Mbps52Mbps
Mini Living Hall2nd Floor106Mbps53Mbps

[Update – after we published the video, one member in our Facebook group said that turning off 2.4Ghz in the Deco will result in better WiFi speed, so we decided to give it a try]

Second Test Result [WITH 2.4Ghz off]

With the location unchanged, here is the speed that we are getting:

LocationFloorDownload SpeedUpload Speed
Living Hall1st Floor301Mbps53Mbps
Master Bedroom2nd Floor285Mbps52Mbps
Mini Living Hall2nd Floor250Mbps53Mbps

We are getting maximum Wi-Fi coverage in a double-story house with no Wi-Fi dead zones.

Remember the seamless internet that we’re talking about? We actually did a live Skype call by placing a laptop on the first floor, while one of us holding the Note 9 walking between floors and rooms.

With this fast roaming enabled, TP-LINK will automatically route me to the nearest Deco M5 to maintain optimal speed especially when I’m moving around.

  1. Hi, i want to use the 2nd ethernet port on the deco m5.
    Previously i set on the vlan inifi iptv, now when i turn of the vlan option, there will be no connection.
    I dont want to use the iptv, instead i want to use the 2nd ethernet port to connect direct to my sony android tv, how to do that?

    1. Hey azlan, I was having the same issue and like you mentioned, the IPTV/VLAN is connected so you cannot disable it as Unifi needs the VLAN to work.

      How I made this work is to use the Deco mobile app; set the VLAN/IPTV mode as “Custom” instead of “Malaysia-TM Unifi”; put in the internet VLAN ID as 500, priority 0; and tick the 802.1Q Tag. You need to disable the IPTV VLAN button at the bottom.

      You need to start from the reset button on your main deco first.

      1. Hi Adam, thanks for sharing. Im struggling with that now, wanted to use the other ethernet port for another device but it’s not working. pft. let me try your method in a bit.

  2. Hi
    Can i use my current tplink A7 as router and add deco M5 as my wifi enhancer? Reason being I still want to use LAN connection and IPTV at my router area. It seems like deco m5 only have 1 lan connections only. Then the A7 has really bad wifi coverage.
    Will this solve my problem ? My current plan is unifi 500mbps.

    Poh ming

    1. Hi there,

      Absolutely can. Setting up your Deco M5 as access point is a smart choice.

      Make sure to turn off your A7 WiFi to minimize your WiFi intereference (just let Deco M5 broadcast will do), you will have a better WiFi experience this way.

  3. Hi,
    I recently installed the Deco M5 replacing my D-Link DIR-842 to overcome issues with low signal strength and slow speed. The transformation was marvellous. So happy with the device.

    However, I just realised that I have a problem connecting my Astro decoder to the Deco M5 wifi. Still unable to connect these two. Don’t think there’s issue with the Astro decoder as it worked fine with the previous router.

    Would you be able to help on this or direct me to someone who could.

    Thank you

    1. Hi Raj,

      Most mesh WiFi in Malaysia have ready firmware for HyppTV, just make sure to choose the right VLAN setting for the main unit.

  4. Hi, are you selling the TP-Link Deco M5 as a single pack in a box? Does it come with the LAN cable and power adapter? How long is the LAN cable? The power adapter is 2 pin or 3 pin type? Is there a usb port on the device? What is it used for? Can I charge the device using this port? Hope to hear from you soon. Thanks.

  5. hi, what is the diff with 1pack ? if 1 pack the range is not cover far enought, then can i get buy another 1pack to build mesh wifi?

  6. Hi, does the single retail pack come in a box with the setup manual inside? Does the device come with two ethernet ports and a usb port for charging? Or only the ethernet ports? How long is the warranty? Hope to get a reply from you soon. Thanks.

  7. Hi, I’m on Unifi 300mbps plan, on a Tenda AC6 router connected to the modem currently. I’ve bought a 3pack Deco M5 router recently, looking to set up it for my new home with 3500+ build up 3 storey. The main router connected to modem is currently at Ground Floor, with all 4 LAN ports used up for CCTV, Alarm etc. Should i switch the main router (Tenda) with an unit of the Deco M5 and use a switch for the extra ports or continue using the Tenda AC6 as main router + 2 Deco Mesh at 2nd and 3rd floor respectively? Thanks.

    1. Hi Jia Hao,

      You are on a 300Mbps plan and Tenda AC6 is underpowered for it. It can only support up to 100Mbps bandwidth.

      As you intend to connect to CCTV and potentially HyppTV, to be honest, it is not suitable to use Deco as router due to lack of ports. You can opt to upgrade your router to Tenda AC10U, then use your Deco M5 as access point (like what you’re doing now, except upgrade router).

      If you are not planning to use HyppTV, then you may use your Deco M5 as router directly, just get another networking switch so you have more Ethernet ports that you can use.

      1. Any link/tutorial on how to connect M5 to existing old router? I am using standard TP-Link Archer C5 router which I need the port for CCTV and HyppTV.

  8. Hi

    I’m on Maxis Fiber and was wondering if I can do away with the ISP issued Archer C5 router? How can I do this without jeopardising the landline?

    Appreciate any advice you can give.

    Thank you

    1. Hi Latifi,

      E4 should be good enough as it is meant for 100Mbps bandwidth.

      If you’re looking to upgrade your bandwidth in future and you need TP-LINK Homecare (network level protection), then go for M5.

  9. Hi.. I’m on Maxis home fibre plan 100mbps that comes with a dect phone. The dect phone is directly connected to the Maxis router.If I replace the Maxis router with the deco M5 unit, how do I get the dect phone to work?Do I connect it directly to the deco unit as well?

    1. Hi Sherry,

      For dect phone to work you will need to be using Maxis’s router. Here’s what you can do.

      You can just connect your Deco M5 to your existing router and use it as AP mode. Turn off your router’s WiFi to minimize the WiFi interference and let your Deco M5 handle the WiFi broadcast.

    1. Hi Tze Shuen,

      Same process. You can use it as router mode or AP mode.

      If you need dect phone, then you can only setup it as AP mode.

      1. Hello. I have a TP-LINK Archer C7 that I prefer to use as my main router. My Deco M5 3-pack is on its way here and I plan to have them in AP Mode. My question is, when the Decos are set up in AP Mode do they broadcast separate WiFi networks aside from my main router’s? I prefer to have the WiFi in my main router remain enabled and the Decos just expanding the range. So in total just 1 big network in our home (well 2 if I have both 2.4GHz and 5GHz SSIDs). Thanks. 🙂

        1. Hey Vince,

          You can setup both WiFi (Archer C7 & Deco M5) to be enabled, but we’d advise to turn off the main router’s WiFi to reduce WiFi interference.

          Deco M5 should be good to steer your band frequency from 2.4ghz to 5ghz whenever you’re in 5ghz range. With that being said, still up to you lah on how you want it to be 🙂

          1. If I’m using TM unifi standard modem and router (separate units) how do I turn off the main router’s wifi to let the Deco M5 take over without interference?

  10. Hello,
    Im replacing my damage unifi standard wifi router with this M5.However after following all the steps even get an assist from unifi via phone, it happens to have a problem when it is in tetsting the internet mode.The router start to blink red light which obviously have an issue.I also has changed the DNS server but still not work.Please advise.Thanks

  11. Hi Team,
    Hope you could help me solve the problem.
    ISP: Astro Maxis IPTV
    Already set to Vlan PPPoE IPTV 823, Vlan Internet 621, I’m not using DECT.
    Choose Maxis 1
    Choose MAC default address

    Testing 3 days 3 nights with few hundreds option can’t up the Internet connection: message from the deco app: unable to connect to Internet. So far IPTV no problem, but no internet???? Please help SOS!!

  12. My Unifi is 300Mhz. I using TP-Link AC1750. What is the best combination Mesh WIFI model to used. TNnet offer Mesh WIFI M4. But I look around more recommend to M5.

    1. Hey there,

      Yes, Deco M5 is still the best TP-LINK Deco Mesh at an affordable pricing, if your budget allow, do go for Deco M5.

  13. Sir, I am currently with Unifi 800mbps and Dlink 850L router. I would appreciate if you could suggest me between TPLink M5 or DLink Covr 2202 for my mesh WiFi. Thank you so much and have a great day.

    1. Hi Rizal,

      Can I know what issue are you facing? Are you looking to extend your WiFi coverage?

      Deco M5 is designed to support up to 400Mbps, so definitely not suitable for you.

      An apple to apple comparison is Deco M9 Plus VS COVR 2202, both comes with Tri-Band (backhaul) and support up to 800Mbps bandwidth.

      1. Dear Sir,

        Well actually, I am facing a slow speed where I can only get 200Mbps while my Unifi plan is 800Mbps. My router is a default Dlink 850L from TM. Oh yeah, I am looking forward to achieve the optimum speed from my current TM Unifi plan.

        Or perhaps I can only change my router to DIR-2660 AC2600 Smart Mesh Wi-Fi Router? I really appreciate your help in resolving the problem. Thank you.

  14. Hi I bought a set of 3 Deco M5 from you previously.

    Here is my problem:
    Ground floor Living hall – 100mbps no problem.
    1st Floor Study hall – 70-80mbps
    2nd Floor Small living hall – only 30-40mbps

    What should I do to improve please? Thanks!

    1. Hi Rainey,

      What is your current ISP bandwidth plan? If you bought from us, you may reach out to us on Shopee / LZD for faster response.
