TP Link Deco M4 Whole Home Mesh Wifi System Review 

I know nothing, and just finished setting it up. It is easy, just need to be patient with the led lights to do their thing. My wife was getting around 10-15 Mbps in her study at the end of the hall. I put one in her study and now getting around 180 Mbps. So far, so good. .... Thanks, and be well!

This system is fantastic. I use 5 Decos in a 3500 sq ft home with a 2 car attached garage and a 4 car detached garage. It covers everything and gives me great speeds. Worth the money. Great review!

These things are amazing. Especially for gamers. You can set QoS with a few phone swipes and it works fantastic. I was really blown away by these.

the TPlink app Tender, go to the tool at bottom right side of the screen, select operation mode to select Range extender or access point.

That’s a good idea you have about units having separate SSID for the 2.4ghz and 5ghz, hope they can issue an update which would add this functionality, and like you, after several hours I also had no luck connecting these units together with Ethernet cables, very frustrating indeed. Just one point, I’m in the U.K. and I’m finding I don’t get as much coverage as you guys in the USA, perhaps I have some interference issues, perhaps it’s because my house is a stone/brick build and I think you guys have predominantly timber frame construction , but I find I need 2 units on each floor to get full coverage and then my results are more akin to yours. Thanks for the upload !

Nice video. They must have fixed the backhaul problem since the video was made. Was very simple here as I just connected the two units via an ethernet cable and they were linked. You can see an "s" shaped wire in between the two units in the App vs the wifi arcs. Lovin the units as they work very well.

I upgrade from a Archer ac1900 and just bought the Deco M4 (3 pack) from Samsclub for $130 plus $15 for 3 year warranty. I'm not very techie but not a novice either and setting was straight forward per instructions. I have all three router up and running less than 30 minutes. I have 2400 sq ft home and this mesh system cover very well currently with no dead spot. My provider is at 150mbps ISP connection and I'm getting 135 to 140mbps with wired to my pc and my iphone x is getting around 50mbps to 80mbps wireless wifi depending on the location I'm at in the house. TBH, 50mbps is more than enough to run anything up to 20 connected devices with no lags in the house because I use to have that speed constantly with my Archer ac1900 and experience no problems. When my extended family visit and I have over 30+ device connected, I have no issues with the Archer ac1900 also for over 6 years. So all in all, this Deco M4 is an upgrade and it is over kill in speed for normal home use. The best part is tplink give a 2 year warranty and I bought an extra 3 year totaling 5 years of warranty from square trade. It should pay for itself in 5 year and I will upgrade to AX at that time.

Thanks man. I was looking into this system, and found a 2 unit system at walmart right at my price point. I appreciate the review, and this increases my confidence this may be a good choice. I'm currently using a wifi repeater and it's garbage. These speeds look very hopeful for me, especially considering I'm getting 20 mbps down now.

oh, I wanted to see some live speed results as Im installing 6 of these next week, I was also going to use an Ubiquiti nano beam for the backhaul to another building.

I had been looking into a Mesh system but don't want to spend the $300+ for one of those other "popular" systems. And now with Covid and working from home, I would like to spend these nicer days out on the back deck and work. This looks like it just might be the thing! I just wish you were able to get the Ethernet Backhaul to work though....

Thanks I was going to buy the 3 pack but got a 2 pack for 90 dollars. Have a small house so 2 have worked very well.

Just ordered these today. Great video. 1 gig to the house with fiber. Will update. Wifi 6.

Great review. Disappointed on M4 that it does not allow you to create multiple SSID. Thanks for pointing this out.

Great video and thanks for sharing. I live in a rural part of France and envy your high speeds. I miss my direct fiber connection in the US. Thanks to your review, I just ordered this system as my Huawei cellular router is not strong enough for my house. I’ll receive the system in a few days and use your recommendations to set it up. Thanks again for the great video.

Great review with Tribe in the background? Subscribed!!!

My house is over 5 floors and this works really well. Had to buy an M3W to go with it though.

Great review mate ! Just 1 question, do I need to leave one on the units being connected always directly to my main ISP router ?

Thanks so much for your information. You explained well exactly what this product can do and how it does it.

Always good review about product, Thank for u video Majestechs

I looked into this but the device limit was a bit concerning for an IoT addict. Your setup is interesting and I wish you'd do a more in depth video on that!

I added Ethernet back haul using powerline adapters TL-PA8081P KIT and doubled the wifi speed from the satellite node. Both nodes are about the same speed. Would have been better with cables

I bought Deco M4 few weeks ago and I manage to setup Back haul on it, I am not sure if it was because of the future firmware update.

Going to get mine next week, thank for this video showing how it works.

I bought this for my house and I’m confused if I made the right purchase for my internet provider. I have att&t and I’ve been trying to figure out what kind of wifi I have but I’m not that tech savvy. I need help

thank you for making a video with a personality.

Thank you for putting the time and effort into this video

any different between deco m5?

Thank you. Good review. Great bloopers. :-)

Hey man great video...I have the old TP-Link, is this one that much better than the old one?

Hate to hear you couldn't get the wired backhaul to work. That's what I need. Not sure I want to deal with it if it's not straightforward.

Very well explained. Thanks Chris. Very professional!

How about an AVR video series? Love your videos though keep up the good work!

I have problem with playing playstation online. Is it possible I put one of them near ps4 and connect it with cable to the ps4. My router is just downstairs. Plz help

Does Deco M4 has WISP mode or something like WISP mode? (WISP router mode is simply a mode where your wireless adapter acts as both client and WAN port. In another words, you get to connect to another wireless network, use only one IP address they assign to you (and route internet (or whatever) to it), and route traffic to your local (home/private) network - NAT.?

Thanks for the detailed information!

short and sweet. Thanks!

Thanks for the video. One question - what speed test AP where you using? Also, I've heard about ISP's throttling speeds so you don't get your full speed. Do you know anything about this? Can you tell us what to do to keep it from slowing us down? Thanks again.

Simple and Fast. Nice vid! 👍🏼

Great video! Very informative and straight to the point.

Hey man awesome job very very helpful, I have a question. I have my ISP modem and a nigthawk x6 s router. Can I add that mesh to my home network connecting the mesh to my ISP modem or to the router? Thanks.

Very informative Thank you!

I see two other cons. #1. Size, compared to Google Home Wi-Fi those nodes are huge at 8" tall. #2. The location of the indicator light being on top. Again compared to Google where the indicator light can easily be seen from across the room or without getting up. It so easy from your seat to be able to see you are still connected or not. And I have never been disconnected. I've had my Google a little over a year now and it's been worth every penny. But hey...it's Google!

Hey man, can you guide me how to add another unit to my existing setup? Are all units capable of behaving like satellite units?

Great review! I’m actually looking into replacing my ISP’s router and a 3rd party extender with a mesh setup in our house. How do you feel about the Deco vs Google Wifi?

Is this a WiFi alternative or just a add on? I’m not that up to date with current tech

Thank you sir, saw these and though about but ehh, Thanks for the vid. nice new do. MW-DC

When I hard wired the system to my modem, the instructions say unplug the modem and connect the cable to the mesh tower and the modem and re plug.... That didn't work after 2 hours I disconnected and then plug my modem back in and then used the Ethernet cable to connect mesh to modem ... worked better

Would you say this product is still relevant today or there's another at a similar price range you think I should get? Currently have 3 Nova MW3 but they cap mbps to 100 only... Was cheap and my first mesh WiFi. Now time to upgrade

I hope these things also work well in Europe, where houses are made out of steel, concrete and brick rather than wood cartboard and plaster

I don’t understand what’s going on with the new routers that we need extenders and etc, I can connect to wifi routers 2 houses away from mine, not sure who needs these things. Anyone?

Thanks Chris.

Great review! Thank you

Can I use this to replace my existing wifi router, or does it have to be plugged into my existing wifi router in order for me to use it?

You say wire the units together, so I would need to run internet wire to each one or an I just plug them into my jacks

Just thinking of buying this mesh wifi router as the price is not really bad. I’m not tech savy person so here’s my dumb question. My router is currently setup in the basement and i have connected it to a DLink switch. In my living room i have an ethernet port. Can i connect the main deco router through the ethernet port in the living instead of connecting it to the main router in the basement?

Very good observations, you mentioned the AP mode, could you go over that in more detail? How many units can you add to this? I'm looking at a 25K square feet property, just simple country home.

Sorry to ask but how good is this? I own a 130mb fiber connection which by using a regular TP-Link AC750 Universal Dual Band Range Extender gets around 30-50 Mbps to the Living Room. The distance of the Living Room from the VM Router is roughly 9-13m. (On Ground Level while the Router is on Level 1) Do you think a system like this will give me at least 100mpb at that point or will i still have an issue with it?

Have trouble connecting Tv on the wifi and everything else connects well to it. Any suggestions?

Does it matter if I connect the main deco to the modem or to an existing router? Will it affect anything?

I have a decent wifo signal but this would probably help make it reach more rooms

As for me Deco M4 did not work since it is very slow. My pldt fiber is 100Mbps while Deco M4 directly connected through cable reada only 10-15 Mbps or even less. For 6 months until now it is not working,,,very hard to get technical assistance

i also have a 1700 sqf of house with 4 floors incluiding basement, would u advice that i just use 2?

I heard that the the other one that connects thru the walls give better wifi . Is it true

its June 2022, is the Ethernet Backhaul working in the new models/software now?

Can i use 2 pieces for one network in mother child config and 3rd one for another network as Mother and extender independently.

Can i use it in two different building

in today's version, it now has options to turn on/off 2.4ghz or 5hz

Does anyone know if I have ethernet ports in the wall around the house, can I plug each of the nodes into those ports or do they have to connect to each other wirelessly once one of them is wired to the router?

How are these compared to the Netgear, Eero, Google and Amplifi routers that made a video about?

If I get 950 up and down from fios and I hardwire my pc to the tp link which is hardwired to the main tp link which is hardwired to the modem, will I get full 950 or just 867?

What about the new deco p9 essential an M4 with powerline so you get router speeds at all the satellites

This vs EAP225? I have a couple EAP225v3 and its great. Should i replace it with this

Danke, got it on sale

What if i only have 1 pc of deco? Is it possible to put it far from the lan?

How does this system.holds for streaming and playing. Does it disconnect frequently?

how was the speed lets say u were gaming on the mesh sytem but connected to the mesh wired

Do i need an ethernet for each individual router? As in would I have to buy ethernet cables for each of the routers and then wall socket to ethernet adapters in order to connect them to the mesh network? Or do I only need to connect each router that to power?

What’s the differences between the M4 and M5? Which model is newer?

what if modem acts a dual band router? what is the best set up option?

does this work, alone without internet connection

Thanks for the useful info! I’m a new subscriber and was hoping you could help. Is there a difference in quality between the M4 and S4? When I check the specs on the website everything seems to be the same but the only video I found seemed to show slower speed then M4 review videos. Also I was wondering if I can use the deco to replace the modem I’m renting from my internet provider.

Is there any changes of speed deffer from main router to other 2 pack??

No usb for network sharing 😢

How big are your houses? My single router in the farthest corner of the house is more than capable of reaching my garden and upstairs opposite

Is this good for Gaming online??????????

i have this deco m4 mesh but it keeps cutting out

Alguien sabe porque la alexa no se puede conectar a internet con este deco?

This model does not support wifi 6?

Could you use a VPN with this router? Like a paid subscription like NORDVPN?

Does it produce dual signal 2g & 5g?

can you turn off the 5GHz WiFi?

Does it have a limit or is it for lifetime

Can I assign different SSID for 2.4 and 5 ghz? I have a gaming laptop and I want it to connect on 5ghz so that all other devices in my home remain at 2.4 ghz

Aren’t you only supposed to have one router in your house. Wouldn’t three mean that each router has less connection

Do you know if it uses WPA2 AES?

Deco m4 or m5 which one is better?

Can i plug this into an ethernet running to the otherside of my house to provide wifi to that end of the house? I currently have a tp-link 5 port splitter ran to the other side of my house for tv and xbox and would like to plug this into that to provide me with wireless connection on that end of the house

I have a 150mbps ISP connection, but my Deco chokes it to 30mbps maximum! What am I doing wrong???

Can I play my game without lag

Can I connect all the 3 devices by a wired connection instead of going wireless? Like will all the 3 be compatible?
