Modern smartphones running the operating system Android are complex computing devices that constantly exchange data with the outside world. Network failures may occur unexpectedly, blocking internet access or making it impossible to connect to wireless headphones. Users often encounter a situation where Wi-Fi The router is working properly, but the phone stubbornly refuses to connect to it, giving authorization errors or simply freezing at the stage of obtaining an IP address.
In such cases, standard methods such as restarting the device or turning airplane mode on and off may not produce the desired result. Reset network settings is a more in-depth diagnostic tool that resets all communication modules to factory settings. This action doesn't affect your personal files, photos, or contacts, but it completely clears the wireless connection configuration. Understanding how to properly perform this procedure will save you time and frustration when troubleshooting connection issues.
In this article, we will examine in detail the operating mechanism of the operating system network stack and describe the algorithms of actions for various versions AndroidYou'll learn which settings will be deleted, how to prepare for the process, and what to do if the problem persists even after a full reset. Resetting the network deletes saved Wi-Fi passwords and paired Bluetooth devices, but does not affect the user's personal data. Let's look at this process in detail.
What happens when you reset network settings?
When you initiate a reset procedure, the operating system executes a command to clear the configuration files responsible for communication. Network stack The device reboots, clearing accumulated errors, IP address conflicts, and invalid DNS records. This is similar to when you buy a new phone and set up its internet connection for the first time—all settings are reset to their default state.
It's important to understand the difference between a full device reset and a network-only reset. The former removes all data, while the latter only affects the communication modules. Saved Wi-Fi networks, connection history, static IP address and proxy server settings will be permanently deleted. This action also breaks all active Bluetooth connections with watches, fitness trackers and headsets, requiring re-pairing.
⚠️ Attention: Before starting the procedure, be sure to remember the passwords for your primary Wi-Fi networks or make sure they are saved in a cloud account, as it will be impossible to manually recover a forgotten password from the phone settings after the reset.
Often the cause of unstable operation is an address conflict or a malfunction. DHCP client On the smartphone side. A reset forces the device to re-request an address from the router, which often resolves the "connected, but no internet" issue. Additionally, cached network preferences are cleared, which helps if the phone is stuck on a weak signal from a distant router instead of a stable one at home.
Preparing the device for network recovery
Although the procedure is considered safe for personal data, minimal preparation is still required. Make sure your battery is charged. Android- the smartphone's battery is at least 20-30%. Although the process only takes a few seconds, suddenly shutting down the device while system services are rebooting can lead to software errors. It is also recommended to disconnect all external accessories, such as USB cables or docking stations.
If you use corporate profiles or special security certificates to access work networks, please be aware that they will be removed. You may need to reinstall the configuration profile or enter credentials. VPN Connections. Users who configured manual DNS entry to speed up performance or block ads should also note these addresses.
Check if you know the passwords for Bluetooth gadgets if they require a PIN code for pairing (although most modern devices, like TWS (Headphones pair automatically.) It's helpful to have your router handy so you can immediately enter your Wi-Fi password after rebooting your phone. This is especially true if the password is complex and contains many characters.
☑️ Preparing for a network reset
How to reset the network on a clean Android and Motorola device
On smartphones with a "clean" operating system, such as devices from Google Pixel, Motorola, Nokia or Xiaomi (in global firmware versions), the settings interface is as standardized as possible. The procedure here is the most straightforward and understandable. First, open the main application menu and find the icon Settings (usually it's a gear).
Next, scroll down to the section System or Additionally, depending on the version AndroidIn newer versions (Android 10 and above) a direct item is often found Reset settings or Reset optionsOnce you enter this section, you'll see several options for rolling back changes.

Confirm the action by clicking Reset settingsFor security reasons, you may be asked to enter PIN code, the pattern, or the fingerprint you use to unlock the screen. After this, the phone may briefly freeze and then reboot the network modules.
How to reset the network on a Samsung Galaxy
Devices from a South Korean company Samsung use their own shell One UI, which has a slightly different menu structure from the stock one AndroidHere the path to the coveted button may not be obvious to a newbie. Go to Settings and select a section General settings (General Management).
In the list that opens, find the item ResetInside you will see the option Reset network settingsPlease note: there may be an option next to "Reset all settings"—be careful not to confuse them, as the latter will reset all apps and system preferences to factory settings, which is not what we need right now. Select "Reset network."
After pressing the button Reset settings The system will ask for confirmation. On some models Galaxy with the function activated Samsung Knox Find My Mobile may require you to enter your Samsung account password. This is a security measure to prevent remote factory resets by thieves if the device is stolen.
⚠️ Attention: On Samsung smartphones, after a network reset, you may be required to re-accept the user agreement for Google and Samsung Pay services to work, as the reset affects security components.
Resetting Xiaomi, Redmi, and Poco Smartphones
shell MIUI and its new version HyperOS have their own specific arrangement of controls. On devices Xiaomi, Redmi And Poco the path often lies through the section Connection and sharing. Open Settings, find this item and scroll to the very bottom of the list.
There will be a button there. Reset Wi-Fi, mobile networks, and BluetoothIn some firmware versions (especially Chinese or old global ones), this item may be located in the section Additionally -> Recovery and resetThe interface may differ depending on the version. Android (9, 10, 11, 12, 13, 14), on which the shell is based.
After selecting an item, you will be asked to confirm the action. Unlike other brands, Xiaomi Sometimes an additional window appears listing all the items to be deleted, including settings APN (access points) for mobile internet. This is normal. Confirm the reset, and in a few seconds the networks will be reset.
Why doesn't resetting my Xiaomi phone immediately help?
Sometimes, after a reset on MIUI, a full device reboot (power off and back on) is required, rather than simply reconnecting the modules. Also, check if "Wi-Fi Assistant" is enabled in the Wi-Fi settings, as it can automatically switch you to mobile data when the signal is weak, creating the illusion of a problem.
Comparison of Reset Methods: Differences Table
Different manufacturers implement access to system functions differently. Below is a table to help you find the right option on your device depending on the brand and software version.
| Brand / Shell | Path to the menu | Peculiarities |
|---|---|---|
| Samsung (One UI) | General Settings -> Reset -> Network Reset | May require a Samsung Account password |
| Xiaomi / Redmi (MIUI) | Connections and Sharing -> Reset Wi-Fi... | Resets the operator's APN settings |
| Google Pixel / Motorola | System -> Reset Options -> Reset... | The Classic Android Way |
| Huawei (EMUI) | System and updates -> Reset -> Network reset | Often hidden in deep submenus |
As you can see from the table, the logic is similar everywhere, but the section names may vary. The key is to search for keywords: "Reset," "Network," "Wi-Fi," "Bluetooth." If you can't find the item using one path, try searching your phone's settings and searching for "reset."
Alternative methods and hidden commands
If you can't find the desired option through the graphical interface (for example, because the interface freezes), you can use the engineering menu codes. However, this method is only suitable for experienced users. Enter the code in the dialer ##4636##If your operator and manufacturer have not blocked this feature, a testing menu will open.
In this menu, select Information about the phone (Phone information) There may be a button there Run ping test or the option to switch the preferred network type, which sometimes helps "shake up" the module. However, a full network reset using this code is not possible on modern versions. Android (10+) most often no for safety reasons.
Another radical but effective method is to use ADB (Android Debug Bridge) from a computer. To do this, you need to enable USB debugging in the "Developer options" menu and connect the phone to the PC. The command adb shell settings reset wifi Allows you to reset only Wi-Fi without affecting Bluetooth. This is a highly specialized tool for advanced users.
adb shell settings put global wifi_on 0
adb shell settings put global wifi_on 1
This sequence of commands forcibly turns the Wi-Fi module on and off at the system level, which is sometimes more effective than a simple switch in the "curtain." However, remember that using ADB requires driver installation and basic command line knowledge.
What to do if the problem is not resolved
There are situations when even a full reset of network settings doesn't help. In this case, the problem may lie deeper—in the smartphone's hardware or in the router's settings. If the phone can't detect any Wi-Fi networks, the antenna module inside the case may have come loose (especially after a fall) or failed. Wi-Fi chip.
It's also worth checking your router settings. Try changing the broadcast channel from "Auto" to a fixed one (for example, 1, 6, or 11 for the 2.4 GHz band). Sometimes smartphones don't work well with a 40 MHz channel width in noisy environments—try setting it to 20 MHz. Changing the security type from WPA3 on WPA2 It also often helps older or budget phone models.
If nothing helps, and other devices work fine, but this phone won't connect to any network even after a reset and reflashing, it likely requires diagnostics at a service center. Software-based methods have already been exhausted here.
⚠️ Attention: Interfaces and menu names may change with operating system updates. If you don't find an exact match, look for similar names in the "System" or "General Settings" sections.
