In today’s digital space, wireless stability is becoming critical to a comfortable Internet experience. Users of Xiaomi and Redmi devices often face the need to optimize network performance to eliminate interference or improve data transfer speeds. Switching between the 2.4 GHz and 5 GHz bands is the first step to solving most connectivity problems.
Many tech owners mistakenly believe that frequency settings are done exclusively on the smartphone menu, but key changes occur on the router side. It is the router that controls the radio channels, and the phone only adapts to the available networks. Understanding the architecture of your home network will allow you to correctly configure the equipment and avoid typical configuration errors.
In this article, we will discuss in detail the process of changing the frequency range for Xiaomi routers, and also explain how to force your smartphone to work in the right range. You will learn about the technical differences in standards and get answers to questions that will help make your Internet faster.
Before you start technical manipulation, it is important to be aware of the physical difference between the two main frequencies, and choosing the right range directly affects the coverage of the signal in the apartment and the maximum speed you can get on the device.
Differences between 2.4 GHz and 5 GHz bands
The 2.4 GHz band is the most common and compatible with all devices released in the last two decades, and its main advantage is its high penetration: the signal passes better through walls and ceilings, providing coverage at long distances from the router. However, this range is often overloaded, since it runs not only neighbors’ WiFi networks, but also Bluetooth headsets, microwave ovens and baby monitors.
In turn, 5GHz offers significantly higher data rates and is virtually free of interference in apartment buildings. A wide channel allows you to watch 4K video and play online games without delay. The disadvantage is a shorter range and worse ability to bend obstacles: one capital wall can significantly weaken the signal.
Xiaomi’s modern dual-band routers are capable of broadcasting both networks simultaneously, giving the user the flexibility to connect smart homes and old gadgets to 2.4 GHz, and powerful smartphones and laptops to switch to 5 GHz.
⚠️ Warning: When switching to 5GHz, make sure your router and smartphone support the standard 802.11ac or 802.11ax. Older devices may not see a high-frequency network.
Preparation for setting up the Xiaomi router
To change the broadcast frequency, you will need access to the router’s web interface. Make sure your device (laptop or smartphone) is connected to the router network you plan to set up. If you change settings remotely, make sure the current connection is stable so that you don’t lose access to the admin panel in the process.
You need to know. IP-The default address for Xiaomi devices is usually 192.168.31.1 or the domain name miwifi.com. You will also need a username and administrator password. If you haven’t changed them before, the data is often listed on a sticker at the bottom of the device, although newer models give you a password when you first set it up through the app.
☑️ Checking before setting up
It is recommended to configure from a computer or tablet, as the interface on the smartphone screen may be less convenient for detailed configuration. Open any browser and enter the router address in the address bar.
Instructions: change the frequency in the web interface
After successfully logging in to the Xiaomi Mi WiFi router control panel, you will be taken to the main status page. The interface can be done in Chinese or English, but the menu structure remains logical.
Depending on the firmware version, the desired item may be called WiFi Settings, Wireless or have a signal icon. Inside this section, you will see a switch or drop-down list offering a choice between 2.4G WiFi and 5G WiFi. Some models allow you to combine them under one name (Dual-Band Merge function), but for forced separation, this option is better to disable.
To change the frequency, follow the following steps:
- 📡 Find the Settings tab in the top menu.
- 📡 Select WiFi Settings (WiFi settings).
- 📡 Locate the section labeled 5G WiFi and make sure the Enable switch is activated.
- 📡 Give a unique network name (SSID), 2.4 GHz network, so that they can be easily distinguished when connected.
After making the changes, be sure to press the Save or OK button. The router will restart the wireless module and the connection on your device will be interrupted. This is normal system behavior.
⚠️ Note: If you change your network name or password, all your devices will require reconnecting with new options.
What to do if you forget the administrator password?
Set up through the Mi Home app
Xiaomi ecosystem owners often find it easier to manage the network through the Mi Home mobile app, which allows them to change the settings without having to remember. IP-The application is available for Android and iOS and requires authorization in the Mi Account account.
Once you add a router to your device list, click on the icon. From the menu that opens, select WiFi Settings. Here you will see a visual representation of your networks. By clicking on the gear icon or Manage, you can change the network name, password, and most importantly, select a frequency range.
The application interface often offers a Smart Connect mode that automatically switches the client between 2.4 and 5 GHz depending on signal quality. If your goal is to fix the frequency rigidly, this feature should be deactivated by dividing the networks into two separate SSIDs.
| Parameter | 2.4 GHz | 5 GHz | Recommendation |
|---|---|---|---|
| Speed. | Up to 450 Mbps | Up to 1300+ Mbps | For 5G. |
| Coverage | High (up to 50 m) | Medium (up to 20 m) | For 2.4G |
| Impediment resistance | Low. | Tall. | For 5G. |
| Penetration through walls | Good. | Bad. | For 2.4G |
💡
Use different names for networks 2.4 GHz and 5 GHz (e.g. HomeWiFi and HomeWiFi_5G). This will allow you to manually choose which network to connect to depending on where you are in the apartment.
Forced switching on Xiaomi smartphone
Often users want to know how to change the frequency of wifi to xiaomi directly in the phone settings. It is important to understand that in the standard Android interface and the shell MIUI or HyperOS there is no direct button "Switch to 5 GHz." The smartphone chooses the best available network based on Saved profiles and signal level.
However, there are ways to influence this choice: If you split the networks on the router (given different names as described above), then on the phone you just need to forget the 2.4 GHz network and connect to 5 GHz. The phone will hold on to the chosen network until the signal becomes critically weak.
For advanced users, there is a hidden engineer menu, but using it requires caution. To get there, type ##6484## (test menu) or use the engineering menu through settings (depending on the model), there you can find information about the current connection, but manual channel switching is often blocked by the manufacturer for system stability.
If your phone is persistently unable to see 5GHz, check the region in your router settings. Some countries restrict certain 5GHz channels by law. Changing the router region to the U.S. or Indonesia (where there are fewer restrictions) may open additional channels, but this may violate local law.
⚠️ Note: Do not try to modify WiFi configuration system files without root permissions, this can lead to loss of warranty and inability to connect to the network at all.
Problem Solving and Optimization
Even after you set it up properly, it can be difficult. If you're 5GHz down, you might have a suboptimal channel. Mi Home has an optimization feature that scans the air and suggests you switch to a less congested channel. Channel width also plays a role: for top speed, choose 80MHz or 160MHz, but remember that this reduces the number of free channels.
If devices in the back room lose 5GHz network, consider installing a Mesh system or repeater. Xiaomi routers support the creation of a Mesh network, which allows you to expand the coverage of high-speed 5GHz throughout the apartment without losing the speed characteristic of conventional repeaters.
The table below shows the typical symptoms and solutions:
| Symptoms. | Possible cause | Decision |
|---|---|---|
| Phone doesn't see 5G network | Old WiFi module | Check the specifications of the smartphone |
| Unstable ping | Canal overload | Change the channel in the router settings |
| Low speed on the wall | Attenuation of the 5G signal | Switch to 2.4G or add an access point |
💡
The main secret of stable WiFi is not the maximum signal power, but the right choice of frequency range and channel, free from interference from neighbors.
