Modern smartphones Xiaomi, Redmi and POCO These are complex computing devices where connection stability is critical, and users often experience situations where mobile internet stops working after a shift. SIM-Sometimes the Wi-Fi connection becomes unstable, and the Bluetooth headsets are no longer detectable by the system for no apparent reason.
In such cases, standard methods, such as turning on and off air mode, often prove to be powerless. The only effective solution is to completely reset the network parameters to factory values. This procedure does not affect your personal files, photos or contacts, but completely cleans the configuration of all network modules of the device.
In this guide, we will discuss in detail all ways to restore network activity, you will learn about the nuances of working with the MIUI shell and the new HyperOS, and understand when to use radical measures.
When Network Settings Need to Be Reset
It can be difficult to determine when a software failure in a communication module requires user intervention. Often the problem lies in a conflict of profiles or erroneous parameters that have accumulated over the course of operation. Network resets are necessary if you see constant connection breaks or the inability to connect to a known access point.
This procedure is especially relevant after updating the operating system. New versions of Android can change the logic of working with the operating system. DNS-It's also a problem when you switch between carriers, when you have outdated access points in memory. APN.
⚠️ Warning: Before starting the procedure, make sure you remember passwords from your Wi-Fi networks. Once reset, the device will “forget” them, and you will have to enter the combinations again.
Symptoms requiring immediate intervention may be as follows:
- 📶 Smartphone shows network, but pages in browser do not load.
- 🔵 Bluetooth devices are visible in the list, but pairing breaks after a few seconds.
- 📱 Mobile internet is not working, although account balance is positive and coverage is good.
- 🔄 Infinite Receipt IP-Addresses when trying to connect to a router.
If you're experiencing these kinds of things, don't panic, and in most cases, it's a software glitch that's easily eliminated, and it's about understanding what you're doing and what you're expecting.
Preparation of the device for the procedure
Although network resets are considered safe, preparation is not to be neglected. In rare cases, especially on custom firmware or in the presence of system errors, the process can go unusable. The battery should be at least 40-50% charged so that the phone does not turn off at the most inopportune time.
It is important to make sure that the device does not run background processes critical to network activity right now. VPN-services or specialized applications for tunneling traffic, they should be closed or removed, this will eliminate the conflict of software filters with system settings.
☑️ Checklist before reset
It is also recommended to check for system updates, sometimes the network problem has already been fixed by developers in the latest version of MIUI, and a reset may not be necessary, and if the update is not available or does not help, then proceed to immediate action.
Method 1: Classic reset via the settings menu
The most secure and recommended method is to use the standard operating system interface. The path to the desired option may vary slightly depending on the version of the shell, but the general logic remains the same for all Xiaomi devices.
First, open the Settings app and scroll to the bottom of the list. Find the About Phone or Advanced Settings section. In the newer versions of HyperOS and MIUI 14, the feature you want is often hidden under Connections and Sharing. That's where all the communication module management tools are concentrated.
The sequence of actions is as follows:
- 🔍 Find the item “Reset Wi-Fi, mobile networks and Bluetooth».
- 👆 Click on it and confirm the action with the “Reset Settings” button at the bottom of the screen.
- 🔐 Enter the digital screen unlock password or graphical key for authorization.
Once confirmed, the device will reboot network services, the screen may blink, and the status bar icons may disappear and reappear, which is normal behavior, indicating that the communication modules have restarted with clean parameters.
💡
If you use a two-sim phone, check which one is reset. SIM-The card is assigned to the mobile Internet by default, since the settings could return to the factory.
Method 2: Reset through engineering menus and codes
For more experienced users, there is an alternative way through the engineering menu, which allows access to the deep settings of the radio module, but it should be used with caution, since changing the extra parameters can lead to unstable phone operation.
To enter the testing menu, open the Phone app and dial ##4636##. If the code works, the Test menu will open. Select Phone Information. Here you can try switching your preferred network type, for example, from NR/LTE/GSM to LTE Only, to check the stability of the connection.
For a complete reset of network registration data, in some cases, the following sequence helps:
1. Open the menu ##4636##
2. Select "Phone Information"
3.Click "Run Ping Test" (to check)
4. Use the option "Turn off radio" and then "Turn on radio"This method does not remove stored Wi-Fi passwords, but will force the device to re-register on the operator’s network, which is useful if the phone is stuck on a tower with a bad signal and does not want to switch to a more powerful one.
⚠️ Attention: Do not change the settings IMEI This can lead to a complete lock of the communication module and loss of warranty.
Method 3: Resetting the APN access point settings
A common cause of mobile internet failure is the incorrect settings of the APN hotspot, especially for virtual operators or roaming, which can be reset separately without affecting Wi-Fi and Bluetooth.
Go to Settings. → SIM-Maps and mobile networks. Choose the right one. SIM-card, if there are two, and find the item "Access points (APN)». In the list that opens, you'll see the current profile. In the upper right corner of the screen, you'll find the menu where you select the "Dump bottom" option».
After this operation, the phone will automatically download the current settings from your carrier, which often solves problems with slow 3G/4G Internet, and if the profile does not appear automatically, its parameters can be entered manually by taking data from the official website of the provider.

Comparison of methods and possible consequences
Different recovery methods have their own characteristics and scope, and it is important for the user to understand the difference between completely resetting the network settings and resetting only the access point parameters.
| Parameter | Total resetting of the network | APN reset | Radio reboot |
|---|---|---|---|
| Impact on Wi-Fi | Removal of all networks | No influence. | No influence. |
| Impact on Bluetooth | All pairs are broken | No influence. | No influence. |
| Impact on data | Resetting APN settings | Resetting APN settings | Time gap |
| Difficulty | Low. | Low. | Medium |
After any of these operations, the device will return to a "out of the box" state in terms of communications, which means that all the mac addresses will remain the same, but the software configurations will be updated, in most cases, this returns stability.
However, if the problem persists even after all the manipulations, there is a high probability of hardware failure, it can be damage to the antenna module, the plume or the radio chip itself, in which case the software methods are powerless.
💡
If after a complete reset of network settings and flashing the device still does not catch the signal, the problem is hardware in nature and requires a visit to the service center.
