Owners of Xiaomi and Redmi smartphones often face a situation where the device suddenly ceases to see available Wi-Fi hotspots or loses the cellular signal, this can occur after a failed firmware update, installing third-party software, or simply because of accumulated software debris in the system files. Instead of carrying the gadget to the service center, it is enough to reset the network settings on Xiaomi, which returns the communication modules to the factory state.
This procedure only affects the connection parameters: it deletes stored Wi-Fi passwords, Bluetooth device settings and mobile operator configurations. It is important to understand that your personal data, such as photos, contacts, messages and installed applications, will remain completely safe. Network settings reset does not delete the user's personal files, unlike a complete reset to factory settings.
In this article, we will take a detailed look at the algorithm for different versions of the MIUI and HyperOS shell, and how to solve problems if the standard method does not work, how to properly prepare the device for the procedure and what to do if the problem lies deeper than just a software failure.
Preparation of the device before discharge
Before embarking on radical measures to restore communication modules, you need to make sure that the problem is indeed systemic, and users often try to reset the settings when it was enough just to restart the router or reconnect. SIM-However, if you've tried to turn flight mode on and off without any success, preparing for resetting is the next logical step.
While the procedure is data-safe, it is recommended to remember passwords from important Wi-Fi networks beforehand. Once the process is complete, the phone will βforgetβ all the networks it knows, and you will have to enter the access keys again.
Make sure the battery is at least 30-40%, and even though resetting the network is fast and energy-efficient, interrupting the system due to battery discharge can lead to unpredictable operating system errors. If the phone is unstable, it is better to connect it to the power source before you start manipulating it.
βοΈ Checklist before network reset
Standard reset via the MIUI and HyperOS settings menu
The easiest and safest way to bring the network back to life is to use the built-in shell functionality. Xiaomi's interface may vary slightly depending on the Android version and regional firmware, but the menu logic remains the same. You don't need superuser rights or a computer connection.
To start, open the main app menu and find the Settings icon. The top of the screen is usually the search bar, which is the fastest way to find the item you want if you don't want to wander around the menu. Enter a "reset" or "Wi-Fi" request and the system will suggest appropriate options.
If you prefer manual search, follow the paths: Settings β Connection and Sharing β Reset Wi-Fi, mobile networks and Bluetooth. In older versions of MIUI, this item can be located in the Additional section or be placed in a separate submenu Security. Press the reset button, confirm the action with the screen unlock code, and the phone will restart the network modules.
π‘
Use the search in the settings by entering the word βresetβ to instantly get to the desired menu, bypassing long searches by section.
Reset network settings through the engineering menu
If the standard path through the settings is not available or is not working, you can use the engineering menu, which is a hidden part of the system, designed for testing equipment, but it also allows you to perform a deep reset of the radio module. Be careful: changing unknown parameters here can disrupt the phone.
To get into the test menu, open the Phone app and dial the combination ##4636##. The Testing menu should open on the screen. Select Phone information. Here you will see a lot of technical data about the status of the network and the SIM card.
In this menu, you can try to switch the preferred type of network, for example, with the LTE only NR/LTE/GSM, This often helps if the phone is stuck in mode. 2G. To completely reset the radio module, sometimes it is enough to simply select the Turn off radio option and then Turn on radio, which is equivalent to taking out and pasting. SIM-programmatically.
What if the code doesn't work?
Use of the ADB-Teams for Advanced Users
For those who are not afraid of the command line, there is a method of resetting through debugging by USB. This method is especially useful if the phone interface freezes or the touch screen reacts with a delay, not allowing you to properly go through the settings menu (ADB) and USB-cable.
The first thing you need to do is activate the developer mode on your smartphone. Go to Settings β About Phone and quickly press 7 times on the MIUI Version (or OS Version) field. Then a new option will appear in the settings menu Additional β For developers. Inside, find and turn on the USB Debugging Toggle.
Connect your phone to your PC and start the command line. Enter the following command to reset your network settings:
adb shell settings delete global wifi_watchdog_poor_network_test_enabledHowever, it is more effective to use a command to reset specific settings through content, but there may not be a universal one-line for a complete network reset without root rights.
adb shell svc wifi disable && adb shell svc wifi enableThis command forcibly turns off and turns on the Wi-Fi module at the system level, which often solves the problem of βhangβ connection.
What happens to the data after the reset
Many users are afraid of the word "reset" as they imagine losing all photos and correspondence. However, in the context of network settings, there is nothing to fear. The system only deletes the configuration files that are responsible for connecting to the outside world. Your media space remains intact.
The list of what will be removed includes:
- π‘ All saved Wi-Fi networks and their passwords.
- π± Associated Bluetooth devices (watches, headphones, speakers).
- πΆ Settings APN Mobile Internet (access points).
- π Settings VPN and proxy servers.
Once rebooted, the phone will behave like you just bought it in a store for communications, you'll have to reconnect to your home Wi-Fi, enter your password, and re-pair your smartwatch, which is a small fee for keeping mobile internet and calls running smoothly.
| Type of data | Will it survive? | Commentary |
|---|---|---|
| Photos and videos | β Yes. | Gallery untouched |
| Contacts | β Yes. | If saved in an account or on SIM |
| Wi-Fi passwords | β No. | We need to re-enter |
| Bluetooth devices | β No. | Reconjugation is required |
| Annexes | β Yes. | All programmes remain in place |
Solving the problem: if the reset did not help
There are situations where even a complete reset of the network settings does not bring the desired result: the phone continues to lose the network or does not see the Wi-Fi router, although other devices are working normally, in which case the problem may lie in physical damage to the antenna or a deep conflict of software.
Try to extract SIM-You can wipe the card and wipe the contacts with a soft cloth, sometimes oxidation or bad contact can cause the communication module to not register with the operator's network, and it's also worth checking if the phone has a metal plate or a case that shields the signal.
β οΈ Note: If after resetting the phone stopped seeing SIM-card at all (writes "No") SIMΒ» or "Mistake." SIMΒ»), It's possible that the slot or the antenna plume itself is damaged, and then the software methods are powerless, and you need to be diagnosed at the service center.
Another reason may be frequency incompatibility: If you use a phone brought from another region (like the Chinese version of global firmware), it may not support some of your carrierβs Band bands. Check the specifications of your Xiaomi model on the official website and compare them to the carrierβs frequencies.

If resetting network settings and replacing SIM-The card did not help, the problem is most likely hardware or is related to the incompatibility of the operator's frequencies.
Preventing network failures at Xiaomi
To avoid resetting, you should stick to a few simple rules of operation: first, do not install applications from unknown sources that require strange permissions to access the network. Second, regularly update the system, as Xiaomi engineers constantly improve the modem algorithms.
Avoid using memory cleaners and Internet accelerators from dubious developers, who often interfere with system processes, causing conflicts, and use the built-in optimization tools that are already in the Security application.
Periodically, every few months, it is useful to manually remove old, unused Wi-Fi networks from the list of saved ones, which reduces the database of connections and can positively affect the speed of finding available networks in crowded air.
