In an era where every gigabyte of traffic counts and lag in online games can cost you victory, a stable internet connection is becoming critical. Many smartphone owners Xiaomi People often encounter a situation where their router has already been upgraded to a modern dual-band one, but their phone stubbornly only sees the old, overloaded network. This often causes confusion, as purchasing a new device usually comes with advanced communication modules.
The problem lies not in the absence of the function as such, but in the specifics of the operation of radio modules of different generations. Standard Wi-Fi 5 GHz (or 802.11ac/ax) provides significantly higher data transfer rates than the traditional 2.4 GHz band, but has a shorter range. Knowing whether your specific device supports this band is key to properly setting up your home network.
In this article we will take a detailed look at which series and models Redmi And POCO equipped with the necessary hardware. We'll also explore the nuances of software limitations that may obscure this option from the user and provide clear instructions on how to activate high-speed mode.
⚠️ Attention: The settings menu interface may vary depending on the MIUI or HyperOS version. If you don't see the options described, check for system updates or verify your exact device model in the official Mi Community app.
Technical differences between the 2.4 GHz and 5 GHz bands
Before we dive into the supported device lists, it's important to understand the physical difference between the two main wireless frequencies. Range 2.4 GHz It's the most widely used and compatible with all devices ever released. Its main advantage is excellent penetration: the signal easily passes through walls and ceilings, providing coverage throughout the entire apartment.
However, there's a downside. This range is heavily congested: not only neighbors' routers but also Bluetooth headsets, microwave ovens, wireless mice, and even baby monitors operate here. This creates a "messy" effect, where data packets are lost and speeds drop even with a good signal.
In turn, 5 GHz Offers much wider data transmission channels. This allows for real-world speeds of hundreds of megabits per second, ideal for 4K video, video calls, and cloud gaming. However, due to physics, these waves are less able to bend around obstacles and attenuate more quickly over distance.
A complete list of Xiaomi smartphones with 5 GHz support
Company Xiaomi has been equipping its devices with dual-band modules for many years. In fact, the vast majority of smartphones released after 2016 are technically capable of operating on a 5 GHz network. However, support may be limited by software or depend on the regional firmware version.
Below is a table showing the evolution of Wi-Fi standard support across the company's various product lines. Please note that 5 GHz support does not always mean support for the latest standard. Wi-Fi 6, which has appeared in flagships of recent years.
| Series of devices | Examples of models | 5 GHz support | Maximum Wi-Fi standard |
|---|---|---|---|
| Xiaomi Mi (Flagship) | Mi 10, Mi 11, Mi 9, Mi 8 | Yes | Wi-Fi 6 / Wi-Fi 6E |
| Xiaomi (Digital Series) | Xiaomi 13, 12, 11, 10T | Yes | Wi-Fi 6E |
| Redmi Note (Mid-range) | Note 12, Note 11, Note 10 Pro | Yes | Wi-Fi 5 / Wi-Fi 6 |
| POCO (Budget/Mid-Range) | POCO X5, F5, M5 | Yes (in most cases) | Wi-Fi 5 |
| Redmi (Budget Entry) | Redmi 12C, Redmi A2 | Partially / No | Wi-Fi 4 (2.4 GHz) |
It is important to note that the most budget models, such as the series Redmi A or older versions Redmi Go, may only be equipped with a single-position module. In such cases, the device physically cannot detect networks above 2.4 GHz, and software tricks won't help.
Why your phone can't see the 5 GHz network: the main reasons
A situation where the router distributes the network at a high frequency, and the smartphone Xiaomi Displaying only 2.4 GHz is quite common. This doesn't always indicate a malfunction. There are a number of technical and software limitations that block the switch.
The first and most common reason is region. Different countries have different laws regulating frequency use. If you bought a phone intended for the Chinese or Indian markets and are using it in Europe, some channels may be blocked at the firmware level. The communication module simply doesn't know about certain frequencies or considers them illegal.
The second reason lies in the router's settings. Some older router models don't have the ability to separate networks, creating a single SSID (network name). In this case, the device automatically decides where to connect and often chooses the longer-range but slower 2.4 GHz band, ignoring the higher-speed band.
Covert channels and DFS
There's a phenomenon called DFS (Dynamic Frequency Selection). Routers are required to release channels if radars (such as weather or military ones) are available. If your router automatically switches to such a channel and your phone doesn't support it due to regional restrictions, the network will simply disappear from the list of available networks.
Setting up region and hidden Wi-Fi settings
For users who are confident in hardware support but are facing software limitations, there are several solutions. The safest and most effective is to change the region in the system settings. This affects the list of available Wi-Fi channels permitted in the selected country.
To perform this operation, you need to go to the menu Settings → Additional settings → RegionHere, you should select a country with the most liberal standards, such as India, Indonesia, or the United States. After changing the region, the phone will reboot the network module, and the list of available networks may update.
However, be careful: changing the region can affect the operation of some system apps, the weather, and the news feed. If changing the region doesn't help, you can try a more advanced method via the engineering menu, although this isn't available on all models.
⚠️ Attention: Changing settings via the engineering menu (engineer mode) may cause unstable operation of the communication module. Do this only if you understand the risks and are prepared to reset the network settings.
To access advanced settings, codes are often used in the dialer, for example ##6484##, but in newer versions of MIUI, this entry is often closed. An alternative is to use Wi-Fi analysis apps, such as WiFi Analyzer, which will show which channel and at what width your network is operating.
☑️ Check before changing the region
Separating network names (SSID) on a router
Often, the problem is solved not on the phone's end, but on the router's end. Many providers and router manufacturers enable the "Smart Connect" or "Dual Band" feature by default, combining 2.4 GHz and 5 GHz networks under a single name. To the smartphone, this appears as a single network, and it decides which one to connect to.
To force Xiaomi To use a high-speed band, you need to access your router settings. This is usually done through a browser at 192.168.0.1 or 192.168.1.1In the Wireless section, you need to find the frequency separation option and give them different names, for example: Home_WiFi And Home_WiFi_5G.
After this, you need to forget the old network on your phone and connect to the new one labeled "5G." Now the device will use this channel. If the signal becomes weak, the phone will not automatically switch to 2.4 GHz, which guarantees stable speeds but will require manual network switching when moving to a distant room.
Influence of covers and external factors
Physical factors shouldn't be ignored either. The 5 GHz signal has a shorter wavelength and penetrates dense materials less effectively. If you're using a case with metal inserts, a magnetic back, or simply a very thick protective case, this could shield the antenna.
Antennas in smartphones Xiaomi These are often located at the top and bottom of the case. Covering these areas with your hand or any metal-containing material will cause a sharp drop in signal strength (RSSI). This may not be noticeable in the 2.4 GHz band, but at 5 GHz, it will simply "drop out."
You should also consider interference from other devices. If you have a microwave or a powerful Bluetooth transmitter near your router, they may interfere. Try changing the broadcast channel in your router settings to a less crowded one (for example, 36, 40, 44, or 48) to avoid conflicts.
Frequently Asked Questions (FAQ)
Why does the phone's specifications say Wi-Fi 5, but there is no 5 GHz network?
This could mean that the frequency is blocked by software in your region, or your router is configured for channels that your phone's module doesn't support. Also, check if network aggregation is enabled on your router.
Will changing regions increase internet speed?
Changing your region by itself doesn't increase your ISP's bandwidth speed. However, it can open up access to less-noisy 5 GHz channels, which will improve connection stability and reduce ping.
Does Redmi Note 9 support 5GHz network?
Yes, global version Redmi Note 9 Supports dual-band Wi-Fi. However, versions for some markets (for example, the NFC version for India or China) may differ. Make sure you have the global firmware.
What should I do if my phone sees the 5 GHz network but doesn't connect?
Try forgetting the network and re-entering the password. Make sure you're using the correct encryption type (usually WPA2-PSK). If the issue persists, reset the network settings on your phone using the menu. Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and Bluetooth.
