How to Set up the TP-Link Deco M4 Mesh Wi-Fi System

This video guides you step by step to set up your Deco M4. With advanced Deco Mesh Technology, units work together to form one unified whole-home network with the same network name. Devices automatically switch between Decos as you move through your home for the fastest possible speeds.

Why does absolutely everything I buy need a login and an app?

[@waynegranzin3824]

so they can buy and sell you as an advertising target

[@otaskrebche]

Because it connects to a server and saves all the setup info/ downloads firmware/ etc. Also to get your data but it's not just nonsense its part of having IoT all devices need to login somehow to send and receive encrypted data

⁠@@waynegranzin3824yea my 1st thought with this was will they use internet to do some dodgy shit or use it as hot spot for other users or hack me 😂 my previous was better connect one with wire and then put other in any socket but not as strong as this

[@waynegranzin3824]

the thing that most instructions and videos are MISSING: at 1:16 it starts talking about using the deco as a router OR access point. but it seems the physical setup at that point is the SAME, regardless of which you choose... i'd imagine the bulk of typical, first-world users are getting their service from a single device that is both a modem AND router. and if so, are there router functions on that device that should be disabled when using the s4 mesh system in router mode?

[@countpuchi]

Id reckon if you already have a TP Link router thats compatible with the mesh system just turn it into an access point

[@Savsal12]

I think he’s talking about if you have an isp modem/router in one device.

Can you use these wireless? My wifi modem is wired and I just want to plug these in with the power cables in the rest of the house, I don't have network cables in the rest of the house.

[@spudpud-T67]

I'm after the same answer. I have two of these but when streaming in my lounge (5m away from remote deco, but no line of sight) the wifi cuts out, on and off constantly, once a minute. I want to know if I can use the deco I have wired into the modem (which has it's own wireless) and move it into the lounge to have line of sight to my laptop for streaming.

[@spudpud-T67]

I read that we can't use a deco as repeater to an existing wifi network. One deco must be wired to the router.

[@letisiasart]

Does it matter which connection type you choose? Where can you find the necessary information to find that out?

[@WatcherdenAMG]

Getting the necessary info about your ISP is BEYOND challenging...why couldn't this simply have a WPS button to clone the network like the small extenders do?

Just set up the AC1200 pack, which has M4s, which you should know to select and not AC1200 when setting up the thing, if not it will be found. Other than that works so much better than I could ever have hoped for. My router (wired) has a 200Mbps connection. Near it the wifi is around 120-150Mbps. Down here in the first floor I never got above 20Mbps in a good day, less when raining. Now? Let me check... Lol. Its crazy...the speed is actually faster than the wired connection, with 218.15 Mbps Download and 123.6 Mbps Upload (using 2 M4s upstairs and 1 downstairs). This is NUTS. Now I can finally play PS5 on the Steam Deck or buy the new PS Portal :3 Amazing product. Damn!

[@spaceork6973]

If your deco is not working is because you do not need to restart your MODEM, And open the app only when you linked your first deco to the modem.

Question: can I set up a guest network when using deco in access point mode? Background for my question is that nowadays most user have a combo device of modem, router and wlan access point. But the wlan access point might be of outdated standard. In this case it makes no sense to use deco in router mode, because using a Lan router configuration parallel to a wlan router configuration is complicated and might interfere in some way. But maybe guest network is a must? So is it possible or not, because almost any wlan access point on the market does not provide guest network in access point mode. To me this feature is an absolute must.

I just bought TP-Link Deco M4 - 3 pack. I'm disappointed because I cannot cover my home with the signal. I have a router in my basement and I thought I would connect 3 devices in a chain to go up to 2nd floor. It seems that the device connected via LAN transmits WiFi signals separately to both additional devices, so I have a medium connection to the first one and a low one to the second. So apparently the one connected via LAN has to be in the middle. I probably try to get a refund (unless there is an option to create this "chain" connection to pass the signal from first to third via second)

To complete my previous post: Also, if you go the Router mode, with the Deco app you will be able to use the full functionalities of Network controls that it provides as you will be using the equipment as a router. If you go the Access Point mode, the Network controls in the app are not available if I understood correctly from some KZbin videos.

Access points mean they just connect wireless devices to network without any interference, so yes, that means that they won't interfere in the connection with features such as network controls. You'll have to do that on your main router.
