adb shell am broadcast -a android.intent.action.AIRPLANE_MODE --ez state false

3. Conflicts with firmware and updates

About 30% of the time, when Wi-Fi does not turn on Xiaomi, are associated with incorrectly installed updates or "raw" versions MIUIThis is especially true for devices participating in the beta testing program or for models with custom firmware.

Check the current firmware version in Settings → About phone → MIUI versionIf it ends in .DEV (development) or .BETA, there's a high chance the bug will be fixed in the next update. In this case:

• 🔄 Update to the latest stable version via Settings → System Update.
• 📥 If the update does not arrive, download the full firmware package (Fastboot or Recovery) from the official website Xiaomi and install manually.
• ⚠️ If the problem worsens after the update (for example, the Wi-Fi option in the settings is missing), follow these steps Rollback via Mi Flash Tool.

For devices with unlocked bootloader (Bootloader) and custom firmware (LineageOS, Pixel Experience) the algorithm is different:

1. Check the firmware compatibility with your model on the developer's website.
2. Make sure that the correct firmware was flashed during installation. vendor And firmware files.
3. If Wi-Fi doesn't work after flashing, try reflashing the module. WCNSS_qcom_cfg.ini through TWRP.

How can I check if the problem is hardware related?

• 🔍 Connect your phone to your PC and check the logs via ADB command:

  adb logcat | grep -i "wifi\|wcnss"

  If there are lines with errors E/WifiHW ( 1234): Failed to load driver - this is a sign of a hardware failure.

• 📱 Check your Wi-Fi connection Safe Mode (Press the power button → "Restart in Safe Mode"). If Wi-Fi works, third-party software is to blame.

Some applications (especially those that require root access (or aggressively optimize network performance) can block Wi-Fi. The most common culprits are:

• 🛡️ Antiviruses: Avast, Kaspersky, 360 Security Sometimes they block network connections, considering them suspicious.
• 🔋 Battery optimizers: Greenify, AccuBattery, Battery Doctor may turn off Wi-Fi in the background.
• 🎮 Cheats for games: programs like GameGuardian or Freedom modify system files, which leads to crashes.
• 📡 VPN and proxy: Psiphon, 1.1.1.1, Orbot sometimes conflict with Wi-Fi settings.

How to find the culprit:

1. Boot your phone into Safe Mode (as described above). If Wi-Fi works, the problem is with third-party software.
2. Uninstall recently installed apps one by one, checking Wi-Fi after each uninstall.
3. Use ADBTo find the conflicting application:

   adb shell dumpsys wifi | grep "blocked"

   The output will indicate the application packages that are blocking Wi-Fi.

If you use Xiaomi EU ROM or other custom firmware, the problem may be in incompatibility of the Wi-Fi module with the kernelIn this case, only updating to the official version will help.

6. Router problems: why the phone can't see the network

Sometimes the problem is not in the phone, but in routerIf other devices connect to Wi-Fi without problems, skip this section. Otherwise, check:

• 📶 Network type: Some older routers only work in the mode 802.11b/g, and new smartphones Xiaomi (For example, Xiaomi 13) require 802.11n/ac/axGo to your router settings and enable support for all standards.
• 🔒 Encryption type: if the router uses WEP or TKIP, MIUI may be blocking the connection. Switch to WPA2-PSK (AES) or WPA3.
• 📡 Channel and frequencySome channels (e.g. 12-14 in the 2.4 GHz band) may experience interference. Try changing the channel to 1, 6, or 11.
• 🔄 DHCP server: If DHCP is disabled in your router, your phone won't receive an IP address. Enable it or assign a static IP address to it. Xiaomi manually.

To check if your router is at fault, try connecting to a different network (for example, a mobile hotspot) from a different phone. If Wi-Fi works, the problem lies with your router settings.

2. Enter your account password Mi (if attached).
3. Confirm the reset and wait for the reboot (will take 5-10 minutes).

After reset:

• Don't restore data from a backup immediately - check if Wi-Fi is working first.
• If the problem disappears, install applications one by one to identify the culprit of the conflict.

If Wi-Fi still doesn't work after a reset, there are two options:

1. Flash the phone via Fastboot (for instructions for a specific model, look on 4PDA).
2. Contact the service center Xiaomi.
