In the antenna part, the Redmi router AC2100 is equipped with six external antennas, which gives people a very domineering feeling.

Our Verdict

This product uses a large area of ​​openings on the front and bottom to form a good heat dissipation. Besides, the main chassis also uses a large area aluminum alloy heat sink and high thermal conductivity thermal adhesive, which can effectively improve the heat dissipation efficiency of the whole machine. Among them, there is also a Redmi brand logo and two lights on the network and the system in the middle of the front, which makes it easy for users to see the working status of the router at a glance; and the bottom is printed with some product parameter information.

Design and Appearance

Close-up on top, below the simple Redmi logo are the network indicator and system indicator. It will be displayed in red when a fault occurs, and both lights will be white in normal operation.

The power adaptor has a maximum output of 18W.

Redmi Router AC2100 Review – Performance Configuration

In terms of performance configuration, this Redmi router is equipped with a dual-core four-thread CPU, with a single-core clocked up to 880MHz. Compared with traditional single-core processors, the overall performance is greatly improved; on this basis, it integrates 128MB of memory and has 128MB of Flash memory. On the other hand, it provides two frequency bands of 2.4GHz and 5GHz, of which 2.4GHz covers a wider range and 5GHz is faster.

Redmi Router AC2100 Review – Speed Test

The broadband used for the test is Unicom’s 300M broadband. First, the user uses a phone to connect to 2.4G and 5G Wi-Fi respectively to see how the Wi-Fi speed of the Redmi AC2100 router.

Redmi AC2100 router review - Speed test mobile
Left 2.4GHz, Right 5GHz

We can see that the 2.4G frequency test speed of the Redmi AC2100 router reached 72.8Mbps download and 35Mbps upload. The 5G frequency band of the four-way antenna easily ran over the upper limit of theoretical broadband speed, and the download rate reached 353Mbps.

For the home broadband packages, they are usually of two types: 100Mbps and 300Mbps. We can see that the Redmi AC2100 router can fully meet the upper limit of broadband under 5G Wi-Fi, allowing wireless devices such as phones and tablets to be used.

Redmi Router AC2100 Review – Signal Test

At 5GHz Networking

The test was carried in a 70-square-meter room. The Redmi AC2100 router is set in the living room. We have selected 6 test points to test the Wi-Fi signal strength and speed respectively to see how the signal coverage of the Redmi AC2100 router is.

Redmi AC2100 router review - Signal Strength

At each test point, we sequentially test the Wi-Fi speed and the Wi-Fi signal strength.

Here are the results of all the points:

Speed Test locations

5G band Wi-Fi is generally considered to be high in speed but poor in coverage. But after testing on the Redmi AC2100 router, we can find that it can cover a 70 square meters room. No matter the signal strength or the point (5), the signal is still -61db, and the Wi-Fi rate can reach 267Mbps. It can be said that it will not affect our speed that much.

At 2.4GHz Networking

2.4GHz doesn’t have that much speed but high penetration and coverage when compared to 5GHz. So, here is the result of the speed test done on 2.4GHz:

The signal strength at 2.4G is smaller than 5G. Even at point 5, the signal strength is still 51db. But because the rate under 2.4G is not high, the result is that the Wi-Fi rate is reduced to 36.3Mbps.

In general, the 5G Wi-Fi of the Redmi AC2100 router can meet the needs of a home. The coverage is wide and the speed is strong. The 4×4 Mimo in the 5G band of the Redmi AC2100 router is a huge improvement for ordinary users. Although most phones still use 2×2 MIMO antennas and cannot fully utilize the speed of the 4×4 MIMO on the router side, on another level, the four-way 5G Wi-Fi of the Redmi AC2100 router can enhance these devices. The stability, while being able to connect more devices at the same time is excellent.

Redmi Router AC2100 Review – Software Review

In addition to ensuring a fast and stable network experience, this Redmi Router AC2100 also brings a smarter experience at the management level of the device. With the newly upgraded Xiaomi Wifi App, users can not only easily manage routers and access devices, but also enjoy many practical functions. We know that the app has a poor rating of 2.5 out of 5 with many users facing a lot of stability issues and frequent disconnects. However, we didn’t experience any of this. Moreover, the app supports multiple languages as well.

NetEase UU Game Accelerator

For gamers, Redmi router AC2100 adds support for NetEase UU; it can accelerate mainstream overseas games and support the acceleration of console games such as PS4, Xbox, and Switch, which can reduce delays and stutters, thereby bringing a smoother gaming experience.

Note: You will have to buy membership of NetEase UU to use the acceleration feature after the 3 months trial. It’s for 90 yuan ($12) for three months.

App Game Accelerator

At the bottom of the toolbox, you can find the NetEase UU accelerator plug-in. You can make a new account from there and get the 3-month trial.

Device Management

In the device management interface, we can see all the devices connected to the Redmi AC2100 router. You can view their connection time, device information and manage them.

DEvice Management

Child Device Protection

Features like child device protection and access control are very interesting. It’s not just a simple disconnection, but advanced controls such as setting up Internet time and whitelisting/blacklisting of website access. It is very convenient for family members to manage the Internet. Notifications will be sent as soon as the specified device is detected to be online.

Separate Menu for Smart Home Products

And you can see that in the device control of the Xiaomi Wi-Fi application, there is a separate menu for the control of the smart home products. You can implement various intelligent controls on them through the router. In particular, the smart home products in the Xiaomi ecological chain can automatically connect to the Redmi AC2100 router without entering a password.

Intelligent Speed Management

If you don’t want to limit the speed of each newly added device, there is also an intelligent speed limit available. You only need to input the download and upload rate of your broadband. The Redmi AC2100 router can intelligently manage the network speed of all devices. In addition, it also provides video priority and game priority.

How to Connect Your Router To Mi WiFi App?

  1. Download the Xiaomi Wi-Fi application on your phone.
  2. After opening, it will automatically scan the nearby Wi-Fi router
  3. After recognizing the Redmi AC2100 router, click Connect and Bind.
  4. You can choose to automatically set or import the previous settings.
  5. After a few simple steps, you can enter the APP main menu, and the router can only be managed by the currently connected APP, greatly improving security.

How to connect to Mi WiFi App

As we all know, most routers today are divided into two frequency bands of 2.4GHz and 5GHz, so how to choose has become a doubt in the minds of users. The Redmi router AC2100 supports the Wifi dual-band integration function, which can save users the trouble. After this function is turned on, 2.4GHz and 5GHz will use the same name, and the router will automatically select the best Wifi network for the device so that users no longer have to worry about it.

Set Up

Our Verdict

The Redmi AC2100 router can meet our daily needs. After all, 5G Wi-Fi is standard for today’s phones, and it does not make sense to use the 2.4G Wi-Fi specifications. Consumers will choose 5G Wi-Fi with higher speed and less interference, and just leave 2.4G Wi-Fi for smart home products.

The performance of 5G Wi-Fi of the Redmi AC2100 router is beyond our expectations. The Redmi AC2100 router not only maintains signal strength in a good range, it still has 267Mbps download speed when the Wi-Fi signal strength is the lowest. In our test environment of more than 70 square meters of space, there is no place for 2.4G at all. The 5G Wi-Fi of the Redmi AC2100 router can perfectly meet the needs of full coverage and high speed.

Therefore, there’s no doubt that the Redmi AC2100 router is the most cost-effective Dual-Band router. After all, its signal and speed are so strong, and there are very rich management options and functions. These include the game acceleration plug-in for 3 months trial (cost 90 yuan for the 3-month membership) for free.

Where can you buy this product?

You can now buy Redmi Router AC2100 for the lowest price of $37 to $38 from Aliexpress.

Where to buy?
  1. You don’t mention whether the interface and app are in English? Also, can the router be configured directly via web page, rather than using the app?

    1. Yes, it can be set via a web page. Moreover, the web page has much better and more advanced options in comparison to the app.

  2. You never mention about your client is 1×1 or 2×2 ( eg. the phone ). If it’s 2×2, the results are not good.

  3. I just got the router, but I get terrible 2.4 ghz speed of under 10 Mbit download. 2.4 ghz strength is perfekt and no interference tried everything. 5ghz speed are 10 times faster -_-

    1. Yes, we explained that in the article. 2.4GHz network has a wide range but has poor speed, meanwhile, the 5GHz network has a limited range but incredible speed. The difference in speed is really huge. Moreover, that’s the case with almost every Dual-Band router. So, it is recommended that if you have a high-speed broadband use the 5GHz network. It’s a lot common now and supported in most of the phones, laptops, and devices.

  4. Jaký je lepší router Tenda AC 23 nebo Xiaomi redmi AC 23 a jaký jsou obou routeru nejnižší ceny na trhu či ve světě.

    1. In terms of design …Tenda ac23
      In terms of signal strength ….Tenda ac23 (has 6dB vs Redmi as 5dB)
      In terms of hardware…Redmi AC2100 (redmi has dual-core CPU @800MHz, while Tenda has a 1GHz single-core CPU with a co-processor and lower memory)
      In terms of App use & support, Redmi AC2100 router (Mi-WiFi App is way better than Tenda-WiFi app, however, both have connectivity issues sometimes)
      In terms of features…Redmi AC2100 (Game booster, better device management, child device protection, Automatic Xiaomi smart products linking via App, device management is the best)
      Speed and bandwidth are almost the same and both support IPv6. The price difference isn’t that much. However, as for a brand recognition, I’ll go for Redmi because they have really great products. Redmi Router AC2100 has a price of around $32 to $40 on Aliexpress and other Global Chinese stores. Meanwhile, Tenda AC23 has a price of around $40 to $50 and the availability is really low since the only shop which was selling it is already out of stock now and was selling it for around $45.

  5. Could it set in “client mode” or only in Acess Point? Wich operative mode have it? With 2 router like this can I realize a wireless bridge? Thank you!

    1. Yes, you can make a wireless bridge and use it as a repeater. Download the Mi WiFi app, choose the Wi-Fi mode and then choose “Wireless repeater mode”. You can also set it as a wired repeater.
      And yes, you can create a common separate guest Wi-Fi SSID on it as well.
