Modern smartphones Xiaomi, Redmi And POCO They are equipped with powerful wireless modules capable of operating in the high-speed 5 GHz band. However, users often encounter a situation where the device only sees the 2.4 GHz network, ignoring the faster channel. This can occur for various reasons, ranging from router settings to software limitations within the operating system itself. MIUI or HyperOS.
Enabling this range can significantly increase data download speeds and reduce latency in online games. Bandwidth 5 GHz networks are several times faster, which is critical for streaming 4K video or downloading large files. In this article, we'll cover all activation methods in detail, from checking compatibility to advanced setup methods.
It is worth understanding that the problem is not always in the phone. Often router It's configured differently by default, or the smartphone simply prefers a longer-range but slower signal. We'll look at scenarios where the device's hardware truly doesn't support the standard. 802.11ac or 802.11ax, and what to do in such cases.
Checking technical support for the 5 GHz band
The first step before attempting any modifications should be checking your device's specifications. Not all budget models released several years ago have a Wi-Fi module that supports 5 GHz. If the hardware isn't configured for this standard, software methods won't work.
You can find specifications through official sources or dedicated apps. The most reliable way is to look up the exact processor model and Wi-Fi module in the technical documentation. For a quick check, check the app store. Google Play There are utilities like WiFi Analyzer or AIDA64.
⚠️ Attention: If your smartphone specifications only indicate the standard 802.11 b/g/n, then 5 GHz support is physically unavailable. In this case, you'll need to upgrade to a dual-band router or settle for using 2.4 GHz.
It is also worth paying attention to the region for which the device was released. Global versions (Global) usually have a full set of features, while the Chinese versions (China) may have restrictions on some communication channels due to local regulations. This affects the list of available networks.
Setting up a router to work with Xiaomi
A common reason why a phone Xiaomi The problem with not connecting to 5 GHz is rooted in the router's configuration. Many operators, when installing equipment, combine both bands into one network with a common name (SSID). The smartphone may mistakenly select the weaker 2.4 GHz signal, considering it a priority due to the reception level.
To resolve this issue, you need to log into your router's control panel. This is usually done through a browser at 192.168.0.1 or 192.168.1.1. In the wireless network settings (Wireless Settings) you need to find the option to split the ranges. It is recommended to give the networks different names, for example, HomeWiFi And HomeWiFi_5G.
The table below provides sample settings paths for popular router manufacturers to help you navigate the interface:
| Router brand | Path to settings | Split parameter |
|---|---|---|
| TP-Link | Wireless -> Wireless Settings | Enable/Disable Wireless Radio (for each band separately) |
| Keenetic | My Networks and Wi-Fi -> Home Network | Separate names for 2.4 and 5 GHz |
| ASUS | Wireless Network -> Professional | Smart Connect (turn off to separate) |
| Xiaomi Router | Wi-Fi settings | Dual-band Wi-Fi (turn off bonding) |
After separating the networks, your phone will see two separate connections. Connecting to the network with a 5G set-top box will force you to use the high-speed channel. If this isn't possible, try changing the broadcast channel in your router settings to 36, 40, 44, or 48, as some older Wi-Fi modules in phones don't see channels above 48.
Activation via Android's engineering menu
If your router is configured correctly, but your phone still ignores the 5 GHz network, you can try using the hidden engineering menu. This is a powerful diagnostic and configuration tool. radio moduleIt is accessed by entering a special code in the Phone app.
Enter the command ##4636##If a menu opens, select "Wi-Fi Information." An option may be available here. Wi-Fi Region CodeChanging your region can sometimes unlock hidden frequency channels. However, be careful: incorrect settings can lead to unstable connection.
⚠️ Note: The engineering menu interface differs on different versions MIUIOn newer firmware versions, access to these settings may be restricted or require special permissions. Don't change values you're not 100% sure about.
In some cases, resetting network settings through the same menu or through the standard Android settings helps. Go to Settings -> Connection & Sharing -> Reset Wi-Fi, Mobile Networks, and BluetoothThis action will delete all saved passwords and reset network settings to factory defaults, which often resolves software conflicts.
☑️ Actions in the engineering menu
Using third-party apps to fix the range
The standard Android interface doesn't always allow you to explicitly specify frequency priority. For this purpose, there are specialized utilities that can force the Wi-Fi module to switch to 5 GHz mode. One popular solution is the app WiFi Man from Ubiquiti or WiFi Analyzer.
These apps don't magically "enable" 5 GHz if the module doesn't detect it, but they do help analyze the airwaves and determine whether the phone can even detect networks in this range. If 5 GHz networks are present in the app's scan list, but the system ignores them, the issue may be with Android's network selection algorithm.
There are also macro applications, for example, MacroDroid or TaskerWith their help, you can create a scenario: "If Wi-Fi with the name .._5G is connected, then disable mobile data." This helps the system quickly switch to a fast channel, avoiding the weak 2.4 GHz signal.
Why does the phone see the network but not connect?
Often, the cause lies in incompatible encryption standards. Your router might use WPA3, but your phone only supports WPA2. Try temporarily changing the router's security type to WPA2-PSK (AES).
Problems after updating MIUI and HyperOS
Smartphone owners Xiaomi We are well aware that firmware updates can either improve or worsen the performance of communication modules. After the release of a new version MIUI or HyperOS Users often complain about 5 GHz networks disappearing. This is due to driver updates or changes to regional settings in the firmware.
If the problem occurred after an update, first try resetting your network settings as described above. If that doesn't help, check the community forum. Xiaomi Check for bugs in a specific software version. Sometimes waiting for a patch or, conversely, rolling back to a previous stable version helps.
The system may limit Wi-Fi module operation to conserve battery power, resulting in loss of high-frequency networks. Check the battery settings for network-related system processes.
Frequently Asked Questions (FAQ)
Why does my Xiaomi see the 5 GHz network, but says "Failed to connect"?
The problem is most likely with the password or encryption type. Make sure the password is entered correctly, taking into account the case of the letters. Also, try changing the encryption type on your router to WPA2-PSK (AES), excluding mixed TKIP/AES modes.
Does the case affect 5GHz signal reception?
Yes, it does. The 5 GHz frequency has less penetration power than 2.4 GHz. Metallic cases or cases with magnetic rings can shield the signal, causing the phone to lose network connectivity or the connection to become unstable.
Is it possible to flash the Wi-Fi driver separately on Xiaomi?
No, the Wi-Fi drivers are built into the system kernel and modem firmware. They cannot be updated separately. The only way to do this is to gain superuser (root) privileges and modify system files, which is not recommended for regular users due to the risk of voiding the warranty.
What should I do if the 5 GHz network is gone after a factory reset?
Try forgetting the network on your phone (Settings -> Wi-Fi -> Your Network -> Forget). Then restart your router and phone. If the network is hidden, add it manually, specifying the exact name (SSID) and security type.
