The best purchase, it gets internet at the provider's speed on three floors now. On the second floor the router, first and third the extenders.

Installed in a 10-room hotel. 1 central at the reception from provider COSMOTE and two on the first floor. The connection is 50 Mbps and with 28 clients on the last one, I get between 30 to 40 Mbps. I recommend it!!!

Finally, I solved the problem I had with the wifi issue. Perfect signal throughout the 85 sqm house, even in the garage and on the roof. Very easy installation and with user instructions for beginners. The best thing TP-LINK has released.

It's worth every penny. It covered a 110 square meter house with walls in between.... The speed of my internet is not great, resulting in either a weak signal or being disconnected in certain areas of the house.... Now everything is perfect, it never disconnects me again.... Besides the occasional lag, it solved every signal problem I had in every corner of the house and I even loaded it with six or seven devices.... Now it catches signal outside my house.... Full control over who connects and you can immediately kick out unwanted neighbors

It's amazing. You download the application and everything is perfect. You need to connect it step by step as it is written in the instructions.

I was really excited. I was expecting and hoping it would help with the network issues at home, but it did much more. I have tried countless repeaters and still had no network in the back rooms (2-10 Mbps max when I did have it). I have several smart devices, cameras, etc., resulting in the network with 25 devices in total not being able to handle it and constantly disconnecting. As soon as I placed a DECO next to the router and one in the hallway towards the rooms... I get 52 Mbps throughout the whole house!!!!! No device lags and everything works perfectly. I want to install one in the basement as well. If it works there while I'm on the first floor, I will come back and say with even greater enthusiasm, "If you don't have mesh, get it immediately and without a second thought."

I used it to connect the internet from the basement of a building to the 2 upper floors where I have short-term rental rooms. Sometimes the signal has been lost on the top floor. Overall, I am satisfied with the product. Its price is very good. Remote management is also very easy and convenient. Additionally, Deco's helpdesk responds very quickly. It was definitely a very good purchase.

Now only mesh network. Deco rocks. In a 3-story office network and it works flawlessly. You move from floor to floor without interruptions. Perfect

The best thing is that it was connected to a VODAFONE H 300s router and a VDSL100 line with very low signal and general Wi-Fi problems, but with the 3 E4 deco, it skyrocketed

As others have written below... I definitely solved my problem. I have full coverage everywhere and very good speed as if I am next to the modem. I definitely recommend it, it is very good and worth 100%.

Generally, the area has a problem and in the detached house we had no internet at all outdoors. We were saved!

In a 3-story house, the router is on the first floor and the office is in the attic... Simply the best thing I have ever bought. After years of frustration and half-measures, this choice simply solved all the problems. From me, 10/10

After installing in a two-story house with a 1-acre garden, I was completely satisfied. Stable speed everywhere throughout the property. Easy installation of the three decos and operation through the app.

It is better than I expected. According to the square footage and floors, I bought the triple. The experience so far shows that I would have done just fine with the double. The additional cost is not much and I appreciated that TP-Link shows moderation in its capabilities. With a 100 Mbps connection, the repeaters were disappointing.

k-a-t-a-p-l-i-k-t-i-k-o

In a 400m2 house with 3 floors and monstrous concrete, with 3 Deco's, it reaches speeds as if I am connected to the Router with a cable. I generally read that they work perfectly, but I admit that I didn't expect them to work so well. Unbelievable.

EDIT: about 2+ months later, they continue to impress me. The mesh function is top-notch, as you don't even notice the transitions from deco to deco when changing rooms/floors.

EDIT 2: 1.5 years+ later, they work flawlessly! They have never experienced any interruptions.

Guys, I tried it in a package of 3 pieces. Simply perfect. Switching from one deco to another in a 2-story house and the router is 30 meters away with zero delay. I highly recommend it without hesitation.

The product is excellent, I installed it in an English language school for one of my clients, which has 3 floors and is around 100 square meters per floor. The router's speed is 50 VDSL (I measured up to 45 meters with a wifi analyzer next to it), and I get over 40 in most areas and on all 3 floors. The only thing that doesn't happen automatically, and I didn't bother to check if there is a setting for it, is that when I move from one floor to another using my mobile phone, it stays connected to the deco of the floor I started from. However, if I turn off the wifi on my phone and then turn it back on, it will connect to the deco of the floor I am currently on. I realized this from the signal strength, as the network name is the same. I am not sure if this is a setting that I missed.

If you have a multi-level space where repeaters lag and don't catch properly, while at the same time you need to print network etc., Deco will beautify your life (literally because it has a super design). I have no words!

A part of the house didn't have any signal before the installation of the E4 TP-Link Deco.
Now we have signal everywhere and it is strong.
We are very satisfied!
