coverage for your entire home with better WiFi speed over the original router provided by TM.
You can view my review of the Deco M4 mesh WiFi system here.

In this article, I will teach you how to setup the Deco M4 mesh WiFi system using the Deco app.
The process is really simple and should take under 15 minutes to get it up and running.

Unifi PPPoE username and password

You will need to the PPPoE username and password if you want to use your own router on TM Uni
network. That can be obtained by calling TM customer service on 03-22411290 and request them
to give you the PPPoE username and password for your Uni account. The password is case-
sensitive.

Sample:

Username: blacktubi@uni
Password: dFgcs5f2szD

Section 1: TP-Link Deco Setup

Now, unplug the router provided by TM and connect it to TP-Link Deco M4. Next, connect the
power and switch it on. Make sure you only turn on this unit now to avoid confusion. The Deco M4
should be connected to the LAN 1 port on the Uni modem.

Section 2: TP-Link Deco app setup

TP-Link Deco mesh WiFi system can only be con gured and managed using the Deco app. The app
is available on the iOS App Store and Android Play Store.

Hi Alvyn. Thanks for the awesome guide. I’ve setup my network as per your guide but I can’t seem to
get the max speed of my uni (500Mbps). I’ve set QoS to zero device with max dl n ul speed to
1000Mbps. Fast roaming is enabled. Appreciate your time to guide me in the right direction. Many
thanks.

It depends on the device you use as well. To be quite frankly, only high-end devices can support
speed up to 500Mbps on good WiFi signal.

Thanks for the reply. What’s your recommendation for a good CAT6 cable? Should I go with
branded names or just a generic brand will do? Many thanks again.
