Xiaomi phone doesn’t see Wi-Fi: a complete guide to fixing a problem

Your Xiaomi has stopped detecting Wi-Fi networks, even though the router is working properly and other devices are connected without problems? This situation is familiar to many owners of smartphones of the brand, from budget Redmi to flagship Mi or POCO. The reasons can lie in software failures and hardware malfunctions of the Wi-Fi module. In 80% of cases, the problem can be solved independently without resorting to the services of a service center.

In this article, we’ll look at all the possible reasons Xiaomi doesn’t see Wi-Fi, from simple setup errors to hidden hardware defects. You’ll get step-by-step instructions with illustrations (for current versions of MIUI 14/15), a table of Wi-Fi standards compatibility with smartphone models, and answers to frequent questions.

Basic checks: router and environment

Before digging into the phone's settings, make sure the problem isn't on the router's side or external factors.This step takes 2-3 minutes, but allows you to rule out 30% of false positives.

• 🔄 Reboot the router. Turn it off for 30 seconds, then turn it on again. Wait for full load (indicators should burn steadily).
• 📶 Check the range of the network. Modern routers broadcast in two bands - 2.4 GHz and 5 GHz. Make sure the phone does not hide one of them (more on this below).
• 🔒 Turn off the filtering. MAC-Go to the router's web interface (usually 192.168.1.1 or 192.168.0.1) and check the Wireless section. → MAC If there's a whitelist/blacklist of devices, temporarily turn it off.
• 🛡️ Change Wi-Fi. In densely populated areas, 2.4GHz channels may overload. In router settings, select the channel manually (e.g., 1, 6, or 11) or activate Auto Channel.

If after this manipulation Xiaomi still can not see the network, and other devices (laptop, tablet) are connected normally, the problem is precisely the phone.

2. Software failures: reboot and reset network settings

The most common reason for the invisibility of Wi-Fi on Xiaomi is a temporary failure of the WLAN module or conflict with background processes.

Step 1: Reboot the phone

It sounds trivial, but it works 40 percent of the time, because MIUI aggressively optimizes the background, and sometimes the Wi-Fi module falls asleep with it.

1. Press the power button for 5-7 seconds.
2. In the menu that appears, select Reboot (do not turn off!).
3. Wait for the full shutdown and automatic switching on.

Step 2: Resetting network settings

If the reboot doesn't work, reset your network settings, and this will delete all stored Wi-Fi networks, passwords and mobile Internet settings, but it won't affect personal data.

1. Open the Settings. → SIM-maps and mobile networks.
2. Slip on Network Settings Reset (in some versions of MIUI path: Settings → Memory → Resettings → Network Settings Reset).
3. Confirm the action and restart the phone.

⚠️ Note: If you are using a dual-band router (2.4 + 5 GHz, after resetting the network, the phone can “forget” the connection settings 5 GHz, you'll have to re-enter the password.

3. Wi-Fi settings in MIUI: Hidden features and bugs

MIUI is known for its many hidden features that can interfere with Wi-Fi, and let’s take a look at some of the most problematic ones.

Problem 1: The 5GHz band off

Many Xiaomi models (especially the budget Redmi Note or POCO M) hide 5GHz networks by default to save charge.

1. Go to Settings. → Wi-Fi.
2. Slip on the three dots in the upper right corner and select Additional Settings.
3. Activate the 5GHz Range Switch (or Wi-Fi 5/6 in newer versions).

Problem 2: "Intelligent switching"

The Intelligent Wi-Fi Switch automatically shuts down Wi-Fi if the signal is weak and goes to the mobile Internet. Sometimes it works wrongly.

1. Settings → Wi-Fi → Additional settings.
2. Find the Intelligent Switch and deactivate it.

Problem 3: Conflict with Mi Cloud

If you are logged in to Mi Account, the system can block the connection to suspicious networks (such as public Wi-Fi in a cafe) to fix this:

1. Open Settings → Xiaomi account.
2. Select Mi Cloud → Synchronization.
3. Turn off Wi-Fi sync (if there is a point).

4. Update firmware and reset to factory settings

If the basic methods don't work, the problem may be in outdated firmware or corrupted system files, and let's look at both.

Step 1 - Update MIUI

The manufacturer regularly releases patches that fix bugs from Wi-Fi.

1. Connect your phone to the mobile internet (or other Wi-Fi network if possible).
2. Go to Settings → About the phone → System update.
3. Click Check Updates and install the available version.

💡

If the update is “hanging” during the boot phase, try downloading the full firmware package (.zip) from the Xiaomi Firmware site and installing it manually through Settings → System Update → Three Dots → Select a firmware file.

Step 2: Hard Reset (Hard Reset)

If the update didn’t work, the last chance before visiting the service is a complete reset.This will delete all data from the phone, so make a backup first!

1. Open Settings → About Phone → Backup and Reset.
2. Select Settings Reset.
3. Confirm the action and wait for the reboot (it will take 5-10 minutes).

⚠️ Note: On models with unlocked bootloader (Xiaomi.eu, custom firmware), the reset may result in a device blink (inoperability.

5. Hardware malfunctions: how to diagnose

If the software methods are exhausted and Wi-Fi still doesn't work, the problem may be the hardware.

Signs of hardware malfunction:

• 🔌 Phones can’t see any Wi-Fi network, even after a reset.
• 📱 In the status bar, the Wi-Fi icon is crossed out or absent at all.
• 🔧 In Settings → Wi-Fi on/off slider is inactive.
• 🔍 When connecting to a PC through ADB Adb shell dumpsys wifi returns WifiState Machine is not running.

What could have broken?

1. Wi-Fi antenna, often departs after falls or disassembly of the phone, checked by a multimeter (resistance should be ~50 Ohms).
2. A WLAN module (Broadcom chip or Qualcomm) fails when overheated or power surges.
3. Saled contacts. Oxidation or detachment of tracks on the motherboard.

If you suspect a hardware breakdown, but do not have experience in repairing, do not disassemble the phone yourself - this can aggravate the situation. Contact the Xiaomi service center (addresses are available on the mi.com website). The average cost of diagnosis is 500-1000 rubles, repairing the antenna - 1500-3000 rubles.

6. Alternative methods: debugging and hidden functions

For advanced users, there are a few non-obvious ways to bring Wi-Fi back to life: They require access to ADB or an engineering menu.

Method 1. Reset MAC-wifi addresses

Sometimes the network can't see the phone because of a conflict. MAC-Addresses (for example, after cloning an address on another device) to reset it:

1. Activate Developer Mode: Settings → About Phone → MIUI version (tap 7 times).
2. Return to Settings → Additional → For developers and enable USB debugging.
3. Connect your phone to your PC, open the command line and type in: adb shell su ifconfig wlan0 down ifconfig wlan0 hw ether XX:XX:XX:YY:YY:YY # (replace MAC) ifconfig wlan0 up XX:XX:XX:YY:YY:YY — new MAC-Address (can be generated here).

Method 2: Engineering menu

You can manually test the Wi-Fi module in the engineering menu.

1. Open the Phone app.
2. Enter the code: ##4636###.
3. Select Wi-Fi information and check the Wi-Fi status. If it's Disabled, the module is faulty.

💡

If there is no Wi-Fi information item in the engineering menu, your Xiaomi model does not support this feature (relevant for new devices on MIUI 14+).
