Disconnecting 5G network on Xiaomi routers: the full guide

Modern routers from Xiaomi by default operate in dual-band mode, broadcasting the signal simultaneously at frequencies of 2.4 GHz and 5 GHz. This technology, known as Dual-Band, is designed to provide maximum speed and stability of connection for all gadgets in the house. However, not all devices correctly perceive the presence of high-speed range, which often leads to communication breaks or the inability to connect smart equipment.

Users are faced with the need to force the Xiaomi router to work only at low frequency. This is especially true for older smartphones, low-end IoT devices such as light bulbs or sockets that do not physically support the 802.11ac standard. Also, turning off 5G helps in situations where the high frequency signal badly breaks through walls, creating “dead zones” in the far rooms of the apartment.

In this article, we will discuss how to change your wireless settings via web interface and mobile application. You will learn the difference between a combined network name and separate SSIDs, and how to set up channels for maximum performance. It is important to understand that completely disabling the 5 GHz band will reduce the maximum possible Internet speed, but increase compatibility with older hardware.

Why it is necessary to turn off 5G range

The main reason Mi Router owners are looking for a way to turn off the high-frequency signal is because of the algorithms of the client devices. Many gadgets, seeing two networks with the same name (if the unification function is enabled), can try to switch to 5 GHz, even when far from the router, as a result, the signal becomes unstable, as the waves of this frequency are worse than the obstacles and fade faster.

In addition, there is a category of “smart home” that works exclusively in the 2.4 GHz band. When you try to configure such devices, the application on the smartphone can automatically connect to the 5G network, which interrupts the pairing process.

Radio interference in apartment buildings is another factor: If neighboring routers are actively using certain channels, switching to a monostand can reduce interference levels. Although 5 GHz is considered less busy, in densely built environments, it is sometimes easier to ensure stability at a single but proven frequency.

⚠️ Note: Before making changes to your network settings, make sure you do not disable access to the router for the device you are setting up from if it only supports 5G.

Preparing for changing the router settings

Before you start modifying the configuration, you need to access the device's administrative panel, which can be done in two main ways: through a browser on a computer or smartphone, or using the official Mi Home app. The first option is considered more reliable, since the web interface provides full access to all hidden parameters.

You'll need to know to enter. IP-The default for Xiaomi is often 192.168.31.1 or the domain name miwifi.com. Make sure your device is connected to the router by cable or Wi-Fi. If you change your wireless network settings, it is best to use a wired connection so as not to lose communication when the modules are restarted.

You'll also need an administrator password. If you've changed it before, use the new data. If you lose your password, you may need to reset your settings to factory settings, which will delete all current configurations, including the ISP settings.

Instructions for disconnection through the web interface

The most complete control over wireless network settings is provided through the browser. Once you enter the router address in the address bar and log in, you will be taken to the main status page. The interface may differ depending on the firmware version (Chinese or global), but the logic of actions remains the same.

You need to find the section that handles the Wi-Fi settings, which is usually labeled as Wi-Fi settings or Wireless Settings. This menu contains a switch that combines the 2.4G and 5G bands. To be able to manage them separately, this switch must be switched to the off position.

Once the bands are disconnected, two separate settings will appear. Find the 5G unit and uncheck the box on "Enable broadcast" or select the "Hide SSID" option if you can't completely disable the software in your version. Remember to save the changes by clicking "Apply" or "OK".

Sequence of action:


1 Enter at 192.168.31.1




2. Authorized




3. Go to Wi-Fi Settings




4. disable the function "Merge 2.4G and 5G"




5. Turn off the 5G Wi-Fi switchboard




6. Save

Configure with the Mi Home mobile app

For users who prefer to control the equipment from a smartphone, Xiaomi has a functional application Mi Home, which allows you to make basic settings without having to open the browser. However, the functionality of the mobile interface can be somewhat reduced compared to the web version.

Open the app and select your router from a list of devices. Go to the settings menu, often hidden under a three-dot or gear button. Find the Wi-Fi Settings item. There should also be a frequency pool switch.

If you don’t see a separate 5G button in the app after splitting the frequencies, it means that your model or firmware version requires the use of a web interface for that operation, in which case, go back to the previous section of the instructions.

Solving network visibility problems after shutdown

Once you have completed a 5G shutdown, some devices may continue to “remember” the old network and try to connect to a now-defunct signal, in which case you need to find your network on your smartphone or laptop in the list of available and select the “Forget Network” action.

Sometimes the router doesn't apply the settings right away, and if the Wi-Fi indicator burns after saving the settings, but the network doesn't appear, try restarting the device, and you can use the software button in the interface, or physically turn off and turn on the power.

In rare cases, especially on Chinese firmware versions, you may need to change your region. Some Xiaomi models block certain channels or features depending on the country you choose.

⚠️ Warning: Don't leave your router without a password or with a factory password after reconfiguring. 2.4GHz open network is highly vulnerable to hacking.

Optimizing the remaining 2.4 GHz network

Since you've only left the 2.4GHz band, it's important to set it up properly to minimize interference. In the wireless settings, choose a 20MHz channel width instead of 40MHz channel width, which will reduce speed but greatly improve connection stability in noisy ether.

You also have to manually select a free channel. Use the Wi-Fi app on your smartphone to see which channels are occupied by your neighbors. Channels 1, 6 and 11 are considered optimal, since they do not overlap.

Make sure that the security mode is set in WPA2-PSK or WPA3. Using outdated WEP encryption or an open network will make your data available to anyone within range of the signal.
