Why Xiaomi doesn’t see Wi-Fi: a full analysis of the causes and solutions

You turned on Wi-Fi on a Xiaomi smartphone, but instead of a list of networks, you see a void or the words "No connection"? The problem is found on all models, from the budget Redmi Note 12 to the flagship Xiaomi 14 Ultra, and there are dozens of reasons for it. In 80% of cases, the malfunction is solved independently, but it is important to correctly diagnose the source of the failure.

This article is not about the template tips like “reset your phone.” We’ll look at hardware and software causes, including rare MIUI bugs, router conflicts, and even physical antenna damage. For each situation, a checklist of actions explaining why they work. If you read the problem, you’ll know exactly if the smartphone or router is to blame, and what to say to the master at the service center.

1. Checking basic settings: what you might have missed

Start with the obvious, but often ignored, that flight mode, geolocation, and energy saving can block network search. At Xiaomi, these features sometimes conflict with the Wi-Fi module because of MIUI optimizations.

Open the notification curtain and make sure:

• 📶 Flight mode is turned off (even if the icon is gray, check the Settings.) → Connections → Flight mode).
• 🔋 Energy saving disabled for Wi-Fi (in Settings) → Battery → Select the mode to select "Performance»).
• 📍 Geolocation is enabled (on some firmware without it, Wi-Fi is unstable).

If the smartphone previously connected to the network, but now it “can not see”, check the list of saved networks:

1. Go to Settings. → Wi-Fi.
2. Slip on three dots in the upper right corner → Additional features → Network management.
3. Remove all networks with an exclamation mark (this means an authentication error).

2. Router failures: why Xiaomi doesn't see only your network

If other devices (laptop, tablet) connect to Wi-Fi without problems, and Xiaomi does not, there may be a conflict of communication standards. Routers with firmware Keenetic, ASUSWRT or OpenWRT sometimes lock devices on MIUI due to aggressive security settings.

Try these steps:

• 🔄 Restart the router (pull the power cable for 30 seconds).
• 📶 Change Wi-Fi channel to 1-11 (in router settings, Wireless section). Channels 12-14 may not be supported on some Xiaomi models for Russia.
• 🔒 Turn off the filtering. MAC-addresses (if included).
• 🛡️ Change the type of encryption with WPA3 on WPA2-PSK (In the router security settings).

Important! If the router is dual-band (2.4 GHz + 5 GHz), try connecting to a network with the 5G suffix. Some Xiaomi smartphones (such as the Redmi 9A) do not support the 5 GHz band on older firmware.

3. MIUI software bugs: hidden settings and resets

MIUI is known for its "chips" that sometimes break standard features. If Wi-Fi is lost after an upgrade or reset, it may be:

• 🔄 WifiService service failure (responsible for network scanning).
• 📱 Shell conflict (for example, after installing a custom theme).
• 🔧 Incorrect regional settings (if the smartphone is purchased abroad).

How to fix:

1. Reset network settings: Settings → System → Additional → Reset settings → Reset network settings.
2. Clear the MIUI cache: Settings → Applications → Application Management → Three points → Show system → Settings → Clear the cache.
3. Check regional settings: Settings → Additional → Region → select “Russia” (if the smartphone is global version).

Critical information: on some firmware for Xiaomi (for example, Redmi Note 10 Pro with MIUI 13.0.4), the Wi-Fi bug is solved only by rolling back on the previous version of the software or installing a patch through Fastboot.

4. Hardware malfunctions: when the "iron" is to blame

If the smartphone does not see any network (including mobile hotspot), the problem may be:

• 📡 Wi-Fi antenna (cable break or contact oxidation).
• 🔌 Communication module (often fails after falls).
• 🔋 Power controller (does not supply voltage to the Wi-Fi module).

How to check:

1. Test in the engineering menu: Dial ##4636## → Phone info → scroll down to Wi-Fi status. If Unavailable status, the module is faulty.

⚠️ Warning: If your smartphone falls or gets wet, don't try to disassemble it yourself. On Xiaomi models, the Wi-Fi antenna is often soldered to the motherboard, and if you do not repair it carefully, you can damage the screen plume.

5. Conflicts with other devices and interference

Wi-Fi can be lost due to external interference, especially in apartment buildings.

• 📡 Neighboring routers on the same channel (e.g. 10 routers on channel 6).
• 🔌 Microwaves, wireless headphones (operate at 2.4 GHz frequency).
• 📱 Other smartphones with hotspot enabled (can interfere with the).

Decisions:

💡

If you have Xiaomi with IR-If you're using a port (like the Redmi Note 10), try turning it off in the settings. In rare cases, an infrared module interferes with Wi-Fi.

6 Rare causes: from custom firmware to viruses

If standard methods do not help, check:

• 🤖 Custom software (like LineageOS or Pixel Experience) Some builds don’t support Wi-Fi on Xiaomi due to lack of drivers.
• 🛡️ Viruses (e.g. AdLoad or HiddenAd) can block network connections).
• 🔧 Incorrect developer settings (for example, enabled Do Not Save Actions or Wi-Fi Debugging).

Instructions:

1. For custom firmware: Install official MIUI via Fastboot or Recovery. Download firmware from en.miui.com.
2. For viruses: Scan your smartphone through Malwarebytes or Dr.Web Light in Safe Mode (press the power button → Safe Mode).
3. For Developer Settings: Go to Settings → About Phone → MIUI Version (stick 7 times), then to Settings → Additional → For Developers and disable all network options.

⚠️ Note: On Xiaomi smartphones with unlocked bootloader (Bootloader), some banking applications (for example, SberBank Online) can block Wi-Fi via Device Admin API. Check the permissions of such applications in Settings → Annexes → Special access → Device administrators.

💡

If the problem occurs after installing custom firmware, return the official software. 90% of the time, it solves the problem with Wi-Fi, even if everything previously worked.
