You are trying to connect a smartphone Xiaomi to the Wi-Fi network at a frequency 5 GHz, but your device stubbornly refuses to detect it, even though other gadgets successfully receive a signal? This problem is familiar to many phone owners. Redmi, POCO and rulers MiThe reasons may lie in both the router settings and the limitations of the smartphone itself—especially if we're talking about budget models or outdated firmware versions. MIUI.

In this article we will look at all possible ways 5 GHz connections on Xiaomi From basic checks to hidden engineering menu settings, you'll learn which models support high-band Wi-Fi, how to bypass regional restrictions, and what to do if the network still isn't showing up. We'll also explain why it's sometimes better to stick with 2.4 GHz, despite the slower speed.

Why Xiaomi Can't Detect the 5GHz Network: Main Reasons

Before you try to force your phone to connect to 5 GHz, you need to understand why it doesn't see it. Here's top 5 reasons, which users encounter:

• 📱 Hardware limitations of the modelSome budget smartphones Xiaomi (For example, Redmi 9A or POCO C31) do not physically support the 5 GHz range due to the lack of a corresponding Wi-Fi module.
• 🌍 Regional blockingIn the firmware MIUI For some countries (for example, Russia or India), support for 5 GHz channels above 140 is disabled by default.
• 🔄 Incompatibility of standardsIf the router is operating in mode 802.11ac (Wi-Fi 5), and the phone only supports 802.11n (Wi-Fi 4), connection may fail.
• ⚙️ Router settingsThe 5 GHz network can be disabled in the router's admin panel or hidden (SSID is not broadcast).
• 🔋 Energy savingAggressive battery saving settings in MIUI Sometimes they block scanning of high-frequency networks.

To pinpoint the problem, first check specifications of your smartphoneFor example, models Redmi Note 10 Pro, Xiaomi 11T or POCO F3 support 5 GHz, but Redmi 8A or Mi A3 (in some regions) - no. If the specifications state Dual-band Wi-Fi or 5GHz, then the problem is not in the hardware.

⚠️ Attention: On some models Xiaomi (especially those released for the Chinese market) 5 GHz support may be blocked at the firmware level. In this case, only updating the firmware to the global or European version will help. MIUI.

Checking 5GHz support on your Xiaomi

Before attempting to connect, make sure your smartphone is capable of operating in the 5 GHz band. There are several ways to do this:

1. View official specifications on the website Xiaomi or in the device documentation. Look for lines like Wi-Fi 5 (802.11ac) or Dual-band (2.4GHz/5GHz).
2. Use diagnostic apps, For example WiFi Analyzer (available in Google Play). Run a scan - if the list of networks contains networks marked 5G or 5GHz, your phone supports them.
3. Checking through the engineering menu (Not available on all models). Enter the code in the phone app:

   ##4636##

   Go to the tab Wi-Fi information and look at the line FrequencyIf there is a meaning there 5xxx MHz, 5 GHz support is present.

If none of the methods have confirmed support, most likely your model Xiaomi simply can't operate in this range. In this case, you'll either have to put up with 2.4 GHz or consider purchasing a new smartphone or an external Wi-Fi adapter (for example, via USB-C).

Configuring your router to work correctly with Xiaomi

Let's say your smartphone supports 5 GHz, but the network still isn't showing up. In this case, the problem might be with your router. what needs to be checked and changed in the router settings:

• 📡 Enable SSID broadcast for 5 GHzSometimes the network is hidden (option Hide SSID or Hide network included).
• 🔢 Check the 5 GHz channelSome channels (e.g. 149-165) may be blocked in your country. Try setting the channel in the range 36–48 or 149–161 (if allowed).
• 🔒 Disable WPA3 security (if used) Some older models Xiaomi do not support this standard. Switch to WPA2-PSK (AES).
• 🔄 Separate 2.4 GHz and 5 GHz networksIf you have one network with automatic switching (Smart Connect), try creating two separate networks with different names (for example, MyWiFi_2G And MyWiFi_5G).

To change the settings, log in to the router's admin panel (usually at 192.168.0.1 or 192.168.1.1) and find the section Wi-Fi or Wireless modeIf you are unsure of the settings, please refer to your router's manual.

⚠️ Attention: If the 5 GHz network disappears even on other devices after changing your router settings, check whether the new settings conflict with local regulatory requirements. For example, in Russia, channels 36–48 and 149–165 are permitted, but the transmission power on some of them is limited.

Enabling 5 GHz support via the engineering menu (for advanced users)

If your Xiaomi It supports 5 GHz, but the network is still not visible. The problem may be due to firmware limitations. In some cases, this may help. engineering menu (or Engineer Mode). This method is suitable for experienced users and requires caution!

Instructions for models based on Qualcomm Snapdragon (For example, POCO X3, Redmi Note 10 Pro):

1. Open the app Telephone and enter the code:

   ##4636##

2. Go to the tab Wi-Fi information (or Wi-Fi Information).
3. Scroll down and find the line Wi-Fi frequency band or Country code.
4. If there is a possibility to change Country code, install US (USA) or EU (Europe) This unlocks additional 5 GHz channels.
5. Save the settings and restart your phone.

For models based on MediaTek (For example, Redmi 9, POCO M3) the engineering menu code may differ:

##36446337##

In this menu, look for the section Connectivity → Wi-Fi and check the range settings.

What happens if you change the Country Code?

Changing your regional code can unlock restricted 5 GHz channels, but in some countries, this violates local radio frequency laws. For example, in Russia, using channels 120–140 without a license is prohibited. This can also lead to unstable Wi-Fi if the selected region doesn't match your actual location.
