Today’s Internet users often face the problem of low wireless speeds, especially in densely built apartments. The main culprit is usually congestion in the 2.4 GHz band, where not only neighboring routers work, but also microwaves, Bluetooth devices and baby monitors. The transition to 5 GHz allows not only to significantly increase data transfer speeds, but also to ensure stable ping, which is critical for online games and streaming video in 4K.
Xiaomi often uses “Smart Connect” technology in its devices, which by default combines both bands into a single network with a common name. This is convenient for ordinary users, but can create problems when you need to force the gadget to connect to a faster and freer frequency. In this article, we will discuss how to disable frequency combination and configure the router so that you can manually select the 5 GHz network on your devices.
Before you start setting up, it’s worth noting that not all Xiaomi and Mi Router models support dual-band mode. Make sure your device has the right characteristics, as it’s not software-enabled to convert a 5GHz monoband router. If the hardware allows, the right configuration will unlock the full potential of your home network.
Testing of hardware support and preparation
The first step before making any changes to the network configuration is to verify the capabilities of your equipment. Many low-end routers, despite their modern design, can only work in the 2.4 GHz band. Trying to find 5 GHz settings on such devices will only lead to a waste of time.
It is also important to make sure that the receiving device (smartphone, laptop or TV) also supports 802.11ac or 802.11ax (Wi-Fi 6).If your gadget is physically unable to catch a 5GHz signal, then no router settings will make it work faster in this range.
To access the settings, you will need a device already connected to the router, either via Wi-Fi or via the router. LAN-Cable connection during setup is preferable, as it will eliminate the risk of loss of communication when the new settings are applied. Make sure you know the login address and administrator password.
⚠️ Note: If you change your Wi-Fi settings, all devices connected wirelessly will lose connection.
Log in to the web interface of the Xiaomi router
The setup process begins with logging into the control panel. There are two main ways to manage the Xiaomi ecosystem: through the Mi Home mobile app (or Xiaomi Router) and through the web browser. The web interface provides more flexible features and clear visualization of parameters for detailed configuration of frequency ranges.
Open any browser on a device connected to the router and enter the standard IP-192.168.31.1 or the domain name miwifi.com. After clicking Enter, the system will ask for an administrator password. If you have not previously changed it, it may match the Wi-Fi password or be indicated on a sticker under the device.
In some cases, especially on routers for the Chinese market, the interface may be in Chinese. This should not be an obstacle, since the menu structure remains logical. You can use the built-in browser translator (for example, in Chrome: right mouse button -> Translate to Russian) to navigate the menu items. The main sections are usually located on the top or left of the screen.
Once you've successfully logged in, you'll be taken to the status home page, which shows the number of connected devices and the current Internet speed, and that's where we'll move to the wireless network configuration sections. The interface may vary depending on the firmware version, but the key terms remain the same.
💡
Remember or write down the new administrator password immediately after logging in if you decide to change it. Restoring access to the router without a password is possible only through a full reset button on the case.
Frequency division: Turning off Smart Connect
The key to “how to switch a router to 5 GHz” is understanding how the frequency combination function works. By default, Xiaomi routers use a technology that creates a single network called SSID for both bands. The router decides what frequency to connect the client based on signal level and load. However, algorithms do not always work perfectly, and devices can “stick” at a slow 2.4 GHz even near the router.
To be able to manually select a network, you need to divide the ranges. To do this, look in the web interface for the Wi-Fi Settings section. Depending on the firmware version, this item may be called Wireless Network or WLAN Settings. Inside you will see a switch responsible for combining frequencies (often called Dual-Band Wi-Fi or Smart Connect).
You need to find an option that allows you to control the frequencies separately. 2.4G and 5G»), You will have two separate fields for entering network names (SSID). You can name them, for example, MyHome_2.4G and MyHome_5G, So you can clearly distinguish between them when you connect, and that gives you complete control over which device is connecting to which network.
☑️ Splitting Wi-Fi frequencies
After you set the settings, the router can reboot. In a few minutes, two networks with the names you give will appear on your device, and connect to the one with the 5G ending or corresponding designation to start using high-speed bandwidth.
Channel setting and bandwidth
Just switching to 5 GHz is not enough for maximum performance. The most important parameter is channel width. In the 5 GHz range, 20, 40, 80 and even 160 MHz are available. The wider the channel, the higher the potential speed, but less range and worse penetration through the walls. For most apartments, 80 MHz will be the optimal choice.
The choice of a particular channel also plays a role. Unlike 2.4 GHz, where there are only 3 non-overlapping channels, there are much more in the 5 GHz range. However, if you live in an apartment building, neighbors can also use 5 GHz. It is recommended to choose Auto mode so that the router chooses the least loaded channel, or manually test the 36, 40, 44, 48 channels (lower range), which are better supported by most devices.
In the web interface, these settings are in the same section where you shared frequencies. Find the Channel Width drop-down menu and select the desired value. Also, look at the wireless standard: for maximum speed, make sure you choose 802.11ac or 802.11ax mixed mode, not outdated standards.
| Parameter | Recommended value | Impact on the network |
|---|---|---|
| Channel width | 80 MHz | Balance of speed and stability |
| Canal | Auto or 36-48. | Reducing interference with neighbors |
| Standard | 802.11ac/ax | Maximum transmission speed |
| Signal power | High (High) | Increase in radius of coverage |
💡
The optimal channel width of 80 MHz provides the best compromise between high speed and stable connection in a city apartment.
Configure with the Mi Home mobile app
For users who prefer to manage a smart home from a smartphone, Xiaomi provides customization functionality through the Mi Home app, which is convenient for quick status checks and basic changes, but may have restrictions depending on the regional version of the router and application.
Open the Mi Home app, select your router from a list of devices. Go to the settings menu (usually three dots or a gear in the corner). Find the Wi-Fi settings section. There should also be a frequency sharing option. The application interface is more minimal, so some advanced settings, such as manually selecting a particular channel, may be hidden or missing.
If you don't find the right switches in the mobile app, it means that your model or regional firmware version only has a web interface available.In that case, go back to the browser-based setup method described in the previous sections.The app is great for monitoring, but deep network configuration often requires a PC.
⚠️ Note: When you update your router firmware through the app, the settings can be reset to factory settings. Always check the network settings after you update firmware.

Solving Connection and Network Visibility Problems
Once you have a 5GHz router, you sometimes have a situation where the network doesn't appear on the list of available devices on older devices, which is completely normal, because old network cards don't physically support that range, and in that case, the device should automatically connect to the 2.4GHz network unless you've turned it off completely.
Another common problem is a smaller 5GHz range, and the signal is worse through concrete walls and metal structures. If the speed drops in the back room or the connection goes down, it's not a router malfunction, but a physical feature of the high-frequency signal, and the solution could be to install the router in a more central position or use the Mesh system.
If you can see a 5GHz network but the connection is constantly resetting or the speed is slow, try changing the channel manually.Perhaps a neighbor has installed a powerful router on the same channel, causing interference. Also check if the power saving mode on the network adapter of your laptop or smartphone, which can aggressively turn off the Wi-Fi module, is turned on.
In rare cases, a complete reset of the router to the factory settings (reset button on the case, clamped for 10 seconds) and reconfiguration from scratch helps, this allows for possible configuration software errors accumulated during operation.
💡
Use Wi-Fi analytics apps (like Wi-Fi Analyzer) on Android to visually assess the load of your channels and choose the freest 5GHz for your network.
