stay away from this product. I have bought so I can connect my Xiaomi smart devices on it. By far the worst thing I have ever bought. Not only it loses the connection with the devices, it looses the devices themselves, and I have to reconnect, each one, one by one.!!!

After a year, it gave up. It doesn't boot and it's a known problem that other users have as well, the problem is at a hardware level and can be solved with the warranty. I bought it for 70 euros, which was worth it. Now, with 120 euros, it's not worth buying, you can get a Mikrotik with WiFi 6 for the same amount of money.

I have had it for 3 years now (bought it for €75) and I have absolutely no problems. I have installed the Chinese firmware and it reaches an amazing distance of 70+ meters (video calls and YouTube easily) from the router. Many times it gives me exactly the speed that the router has, simply connected with a cat6 in wired repeater mode.

I chose this one after reading the comments as I had a terrible problem with constant disconnections on wifi and couldn't figure out why. Vodafone didn't help much and didn't even consider that the problem was with the smart devices we all have. It started for me as soon as I got the Xiaomi air heaters in November. It cost me 70 euros, but once I connected it, I never had any disconnections again, and my wifi calling works fine now, whereas before it was terrible. I don't know if it plays a role, but it connected and set up very easily without me doing anything special. I still have the Vodafone router and the landline, but everything else is on the Xiaomi. Sellers constantly promote tplink, but once again, my insistence on Xiaomi for such devices didn't disappoint me. So, I recommend you get it soon before everyone starts having similar issues and they disappear!

I have it for several months, before I had the A4 Giga version of Xiaomi, which had several disconnections because I had too many devices connected to it. After installing the AX3600, the disconnections became a thing of the past, very easy installation through the application. The connections were made with cat7a cables

After 11 months of use, I have been very satisfied. In Tuya smart home with permanently 35-40 devices connected to wifi, it works perfectly, without disconnections, delays, and other issues...

To fully utilize the capabilities, first you need to install the latest Chinese firmware. In a 100sqm apartment, I can say that I have satisfactory 5ghz wifi throughout the house by placing it in a central room. Those who have purchased the European router with international firmware and switch to Chinese in order for the latest miwifi app (not the one from the playstore) to work properly, will need to change the region of the router to Chinese, otherwise the miwifi app will not work correctly. To do this, you will need to install the Chinese firmware 1.0.17 and connect through putty to ssh and run some commands. See this page and its branches to see how it is done: https://forum.lowyat.net/topic/5071359/+0. After the change is made, you can then upgrade to the latest firmware 1.1.19. I imagine for those who have purchased the Chinese version, this process is not necessary as the region will be set to Chinese by default.

Read the rest of the comments, they have very good analyses. I didn't make any changes with the Firmware and it works perfectly without any issues.

From the moment I loaded smart devices into the vod router. Every two minutes the internet would drop.
I was disappointed even though I realized that the devices were to blame.
The best purchase I have made is this router.
You connect it to the company's router, it recognizes the internet in seconds, you put a password on the new network, and you're ready.
It detects every Xiaomi device in the house .. lamps, cameras, anything instantly.
Different speed in everything.
Opens the cameras in seconds.
What can I say, I solved the problem with the disconnections and freezing ..
Update...
With the Chinese firmware, the router is incredible.
I don't know what to comment on .. the signal?
The speed?
End

This router solved all my problems. Anyone with wifi5 should definitely upgrade to wifi 6 just to be able to send data simultaneously to all devices. Don't choose the cheaper Xiaomi if you want it for gaming, blindly go for the best option. It downloaded and reduced the latency by ten ms compared to the provider's router. I've had it for 4 months with zero disconnections, which I used to have every day with the provider's router. With 100 mbps, I can watch 4K videos simultaneously on 4 devices without any lag. The 5g channel it has is excellent. Attention: only get the Chinese version, the global version significantly reduces performance

Excellent, high-quality, and very stable. It outperformed several devices from other companies that I had tried with poor results, going from 3rd to 1st place. Very satisfied. With the Chinese firmware, it has better performance

Very unstable signal compared to other TPLINK routers. I bought it for better performance, to have greater coverage on the lower floor.

The router is useless with serious range issues when running the International firmware. The reason is that Xiaomi has incorrect limits on its bases for WiFi power in the EU, so it restricts it a lot. The only solution is to install the Chinese firmware, which fortunately can be done very easily through the router's web interface.

Negatives:
- Large size
- Does not have good range

Positives:
- Stable in terms of connection/disconnection (basically does not disconnect)
- Easily recognizes with Aio, just takes a few seconds longer
- Nice interface (from the mobile application)

Conclusion: A bit expensive compared to its range. For setup, I had to contact Cosmote to give me codes so I could set it up (if you have them, it's a 2-minute job).

As for the range, it remains much better than Cosmote's

Much better than I expected.

The connection to the Cosmote router was very easy.
In general, the setup was very simple and I didn't have to do much (from what I've read, I imagine that with Chinese firmware it will have a greater range, but I don't need it).

Currently, I have 25 devices connected simultaneously and I have no problems.

Positives:
- Easy connection
- Easy installation
- Very good network speed
- Good Wi-Fi range
- Smart connect feature to automatically connect devices to either 2.4GHz or 5GHz depending on the distance from the router
- Beautiful UI

Negatives:
- It is quite large (I really thought it was half the size, but okay)
- The AIoT Smart Antenna in the global version of the MiHome App that I have doesn't seem to work. In a second mobile phone that I have with the Chinese version of the app, it immediately found devices without any problem

It is quite beautiful but it has a large volume, it has incredible functionality after the upgrade, it has mesh and it really is an amazing fast router, it never gets stuck, WiFi 6 and it does what it says. In one word, it's awesome

I bought it for exclusive use of virtual desktop on Oculus Quest 2, and I have no complaints. I haven't tried it with the global firmware, but with the Chinese one at 2.4Ghz it reaches two floors down. If you are paranoid about security, you can follow this guide (https://github.com/geekman/xqrepack) to interrupt any communication between the router and Xiaomi (if you are not comfortable with SSH and Linux, I would not recommend it, as there is a risk of rendering the router useless).

I bought it from the internet for 99.99 EUR. I set it up behind the SPEEDPORT ENTRY 2i from COSMOTE. I followed the whole process based on help from WIKI HOW How to connect a router to another to expand a network. The only difference is that I disabled the WIFI from the SPEEDPORT. Everything else is the same according to the guide. Stable with ETHERNET and SPEEDPORT, all other WIFI devices from XIAOMI AX 3600. On a 50 Mbps line (inside the SPEEDPORT it says it syncs at 57), wifi test with OKLA 51.4 on the laptop, and of course all devices are 1080P. SIMPLY PERFECT...

In simple English and in a few words (since there are already awesome and detailed reviews!):
I permanently have 25-35 devices connected (18 Wiz bulbs, multiple mobile phones and tablets for 4-10 people simultaneously, printers, Android TV boxes, televisions) and I haven't experienced any disconnections or freezes in the past 3 months since I got it (since 1/2021).
With the basic Wind router, the system was constantly freezing, we were watching Netflix in low resolution with interruptions, the delays were annoying, the lights were turning on/off randomly, etc. Now, I disabled the WiFi of the old router and it only functions as a modem, which is sufficient!
The only thing that hasn't changed drastically is the signal range, which is slightly better by 10-20%...

The best there is, guys. It's worth every penny. It may be overkill for home use, but at least I never have any problems. With the 3600 wireless, I can handle multiple 4K internal streamings and it doesn't even notice. The app on the phone is really for all users, both soho users and end users. The best part is that you can control the router remotely through the app it provides, and you can see at any moment who is on your network and much more.

It's worth it!

The only thing is, it's a bit... well, it scares people. :DDD

Update (after 3.5 years) The machine is a real beast. It's unbeatable! Excellent value for money. You can find the same thing in Mikrotik or Draytek for an extra 100 €

The best I ever had in a router.

I have 30 to 40 Wi-Fi but in order to connect, if you need to restart, I will wait 5 minutes. If I want to connect a new device from the beginning, it does not accept it and the funny thing is that the device I want to connect is Xiaomi haha 3 different devices I tried and nothing, I have the International version, I put the China one and fortunately they connect quickly but it does not accept all the new devices. They must see the firmware.

Incredible speed.. of course, for the iot it only works with devices for xiaomi mijia aqara (not smart life)

I had the Mi router 4A Gigabit Version on an FTTH Modem router from Inalan with a speed of 250 Mbps download / 250 Mbps upload. I can't say it was impressive, but for long distances, the speed would drop. And with multiple devices connected at the same time, I felt like someone would have to wait. With this router, it's something else! It has Qualcomm network processors and all the latest wireless technologies. On my PC, I can enjoy wireless 5G Wi-Fi, 8K/60 fps YouTube videos with a download speed of around 200 Mbps, Wi-Fi 6 speedtest on my mobile, online seminars, cameras, tablets, and streaming a 7GB original quality movie file on my TV through Plex, etc. It's "enjoyable". I'm writing about my experience after 3 months. If you decide to get it, you'll have the best economical network (especially wireless) at your home.
