Wireless connection issues on Xiaomi smartphones often arise suddenly: the device stops detecting available access points or becomes stuck indefinitely in the "Obtaining IP Address" status. In such situations, a standard reconnection may not resolve the issue, as software errors or profile conflicts have accumulated in the system. Reset Wi-Fi settings On Android Xiaomi, this is a radical but effective method that allows you to return the wireless module to its original state.
Clearing network settings affects not only passwords but also Bluetooth configurations and cellular network settings. This means that after the operation, you'll have to re-enter login credentials for all previously used routers. However, this step is often the only way to restore the connectivity module if MIUI software glitches prevent the device from functioning correctly.
In this article, we'll take a detailed look at all the available methods for performing this procedure: from built-in menu functions to hidden engineering codes. Xiaomi The MIUI shell uses its own navigation features, so it's important to carefully follow the instructions for your operating system version. We'll also cover some tips to help you avoid losing important data.
Why is Wi-Fi not working properly on my Xiaomi?
Before taking any decisive action, it's important to understand the nature of the problem. Users often encounter a situation where the router is transmitting a signal, other devices connect without difficulty, but the Xiaomi phone ignores the network or disconnects after certain periods of time. This could be caused by a previously assigned static IP address that now conflicts with the router's current configuration.
Another common cause is accumulated system service cache files or errors in the wireless module drivers after a firmware update. System bugs They can block the normal operation of the network stack, preventing the phone from authorizing. Physical damage to the antenna is also a possibility, although a software reset is still the first diagnostic step.
⚠️ Note: If your phone has recently been subjected to mechanical impact or liquid damage, a soft reset may not help. In these cases, the problem lies with the hardware and requires diagnostics at a service center.
Sometimes a conflict arises due to the router's security settings, which the smartphone interprets incorrectly. Changing the encryption type or broadcast channel on the access point may temporarily resolve the issue, but a complete reset of the phone's network settings will ensure the removal of all old, potentially erroneous profiles.
Preparing to reset network settings
Restoring network settings to factory defaults requires minimal but important preparation. The most important thing you need to do beforehand is remember or write down the passwords for the Wi-Fi networks you use at home and work. After the reset, your phone will completely forget them, and they won't be restored automatically.
It is also recommended to make sure that your device has Xiaomi The battery charge is sufficient. Although the reset process only takes a few seconds, suddenly shutting down the phone while working with system files can cause unpredictable operating system errors. It's recommended to have a charge of more than 30-40%.
☑️ Preparing for the reset
If you have configured mobile Internet, check if the APN access point is active for your carrier. Resetting the network will also affect these settings, returning them to default values, which may not be suitable for some virtual operators or specific plans. In this case, you will have to manually re-enter the parameters.
Method 1: Reset via the standard settings menu
The safest and manufacturer-recommended method is to use the built-in MIUI shell functionality. This method does not require root privileges and is safe for user data, such as photos, contacts, and apps. It only affects network configurations.
To begin, open the main menu and find the "Settings" icon. Depending on your firmware version (Global, China, Stable, or Developer), the interface may differ slightly, but the logic remains the same. You need to navigate to the section responsible for additional system settings.
The further algorithm of actions looks like this:
- 📱 Find "Connection and Sharing" or "Advanced settings".
- 🔄 In the menu that opens, scroll to the very bottom of the list until you find the "Reset Wi-Fi, mobile networks, and Bluetooth" button.
- 🔘 Click the blue "Reset settings" button at the bottom of the screen.
- 🔒 Enter your screen unlock pattern or password to confirm.
After confirmation, your phone may pause for a second or beep. This means the process was successful. Wi-Fi module It will restart and you will see a clean list of available networks, just like on a new device.
Method 2: Using the engineering menu and codes
For more advanced users, or in cases where the standard menu is unresponsive, there's an alternative via the engineering menu. This is a hidden section of the system designed for hardware testing. It's accessed by entering a special key combination in the Phone app.
Enter the code ##4636## in dialer. If the code is compatible with your MIUI version, the "Testing" menu will open. Here, select "Wi-Fi information." However, it's worth noting that in recent versions of Android and MIUI skins, access to a hard reset from here is often blocked for security reasons.
If the standard code doesn't work, you can try commands to reset specific services, but this requires caution. A more versatile, but riskier, method is to use ADB (Android Debug Bridge) from a computer. To do this, connect your phone via USB with debugging enabled and enter the command:
adb shell svc wifi resetThis command forces a restart of the Wi-Fi service and clears its state. Command line Provides deeper access to the system, so use it only if you are confident in your actions. Entering the wrong password may result in unstable operation of your smartphone.
⚠️ Note: Engineering menu interfaces and available commands may vary depending on the processor model (Snapdragon, MediaTek, Helio) and Android version. Do not change settings you do not understand.
Method 3: Full reset to factory settings
If none of the above methods resolve the wireless connection issue, the operating system files themselves may be corrupted. In this case, the last resort is a full factory reset (hard reset). This step will remove all data from the phone.
Before starting the process, be sure to back up all important files, contacts, and messages. After the reset, they will be impossible to restore without a backup. Make sure your battery is charged to at least 50-60%, as the process may take 10-15 minutes.
Steps to perform a hard reset:
- 🗑️ Go to “Settings” → “About phone”.
- 🔢 Click on “Reset settings” (often located at the bottom of the list).
- 🚫 Select the "Erase all data" option.
- ✅ Confirm the action by entering your Mi account and screen unlock password.
The phone will reboot and begin the cleaning process, which may appear to freeze. Do not interrupt it. Once complete, the device will boot up as new, and you'll need to go through the initial setup again. The Wi-Fi issue will usually resolve with a clean system.
What to do if the phone does not turn on after reset?
If your device is stuck on the logo after a hard reset, try holding down the power and volume up buttons simultaneously for 10-15 seconds to force a reboot. If this doesn't help, you may need to reflash the firmware via a computer.
Setting up Wi-Fi after a reset: Parameters table
After successfully resetting your smartphone, you'll need to reconnect it to the router. It's important to configure the connection settings correctly to avoid recurring errors. Below is a table with recommended settings for stable operation.
| Parameter | Recommended value | Description |
|---|---|---|
| Security mode | WPA2-PSK / WPA3 | The most secure encryption standard. |
| Frequency range | 5 GHz (for speed) / 2.4 GHz (for range) | 5 GHz is faster, but it penetrates walls worse. |
| IP address | Static (DHCP) | It is better to leave the address to be obtained automatically. |
| DNS | Automatic or 1.1.1.1 / 8.8.8.8 | Public DNS can speed up network response. |
| Proxy | No | Use only if required on a corporate network. |
When reconnecting, avoid using WPS, as it often causes vulnerabilities and unstable connections. Enter the password manually. If your router is dual-band, try connecting to a 5 GHz network if you're close to the signal source.
Common mistakes and how to fix them
Even after a reset, users may still encounter error messages. For example, the message "Unable to obtain IP address" often indicates that the router is unable to assign an address to the device. In this case, try going to your phone's Wi-Fi settings, tapping the gear icon next to your network, and selecting "IP Settings" → "Static," manually entering the address (e.g., 192.168.1.150).
Another common issue is constant switching between mobile data and Wi-Fi. This is due to the "Wi-Fi Assistant" feature in MIUI, which disables the wireless network if it detects slow internet connection. You can disable this option in the advanced Wi-Fi settings.
MAC address conflicts are also worth mentioning. Newer versions of Android use MAC address randomization for privacy purposes. Some older routers may block such devices. In the specific network settings on your phone, select "Privacy Type" and set it to "Use device MAC address."
⚠️ Note: The settings interface and item names may change with MIUI updates. If you don't find a setting, check the latest documentation for your firmware version in the official "Services and Feedback" app.
Don't forget that antivirus programs VPN apps installed on your phone may block the network connection even after a factory reset. Try temporarily disabling or uninstalling them to ensure they don't interfere with the module's operation.
FAQ: Frequently Asked Questions
