Modern smartphones based on Android have a complex system for managing wireless connections, which sometimes fails. Users often encounter situations where a device refuses to connect to a known access point, constantly loses signal, or displays an authentication error. In such cases, the standard turning off and on the slider in the notification shade often turns out to be a useless step. A deep reset of connection parameters becomes the only working solution to restore stable Internet.
The procedure for resetting wireless settings may vary depending on the version of the operating system and the manufacturer's shell. On some models Samsung or Xiaomi the menu is located differently than on a clean Google Pixel. However, the general principle of action remains the same: you need to delete the saved network profile or completely clear the device’s network settings. This action is safe for your personal data, such as photos or contacts, but will require you to re-enter passwords for all previously used Wi-Fi networks.
In this material we will analyze in detail all the available methods for solving connection problems. You will learn how to correctly “forget” a specific network, how to perform a global reset of network settings through the system menu, and what hidden commands may be useful to advanced users. We will also look at the reasons why the Wi-Fi module may behave incorrectly and provide a table with a breakdown of common errors.
Deleting a specific network from the device’s memory
The easiest and safest way to solve the problem of connecting to one specific access point is to delete its profile from the phone’s memory. This method does not affect other saved networks, such as home Internet or work office Wi-Fi. The operating system Android stores the configuration of each network separately, including the type of encryption and the saved security key.
To perform this procedure, you must go to the main settings of the device. Find the section responsible for connections, which is usually called “Wi-Fi” or “Wireless Networks”. In the list of available points, find the one you are having problems with. Don't try to just press it to connect; instead, hold your finger on the network name or click on the gear icon next to it.
In the context menu that opens, select the option Delete network or Forget network. The system will ask you to confirm the action, as this will lead to permanent deletion of the saved password. Once confirmed, the phone will instantly close the connection if it was active and clear the cache associated with that router. Now you can try to connect again by entering the password manually.
⚠️ Attention: Make sure you know the current Wi-Fi password before deleting the network. If you forget the combination of symbols, it will be impossible to restore it from the phone settings after deleting the profile without root access.
Sometimes after deleting a network, the phone continues to try to connect to it automatically if the “Connect to open networks” function or a similar smart switching option is enabled. Make sure that in your Wi-Fi settings there are no checkboxes in front of items that allow automatic connection to networks with low signal strength.
If you often move between home and office, give the networks clear names in your phone settings (for example, “Home_5GHz”) so as not to confuse them when manually controlled.
Global reset of network settings
If removing a separate access point did not help, and problems are observed with all available Wi-Fi networks, a more radical approach is required. Resetting network settings (Network Reset) returns all parameters of wireless modules to the factory state. This action affects not only Wi-Fi, but also settings Bluetooth, as well as cellular settings, including access points. APN.
You can perform this operation through the standard Android settings menu. The path may differ depending on the model, but most often it looks like this: Settings → System → Reset settings → Reset Wi-Fi, mobile data and Bluetooth settings. On devices with shell OneUI from Samsung, the path may be as follows: Settings → General settings → Reset → Reset network settings.
After clicking the confirmation button, the system will ask you to enter your PIN code, pattern key or fingerprint to confirm the owner’s identity. This is a security measure to prevent unauthorized persons from accidentally resetting critical parameters. The process takes only a few seconds, after which the device will automatically reboot the network modules.
☑️ Checklist before resetting the network
It is important to understand that this procedure does not delete your personal files, applications or Google accounts. It only affects the connection configuration. However, all previously saved Wi-Fi passwords will be lost, and you will have to enter them again the first time you connect to each access point.
⚠️ Attention: After resetting the network settings, the operator's access point (APN) parameters may be lost. If the mobile data stops working, you will need to enter the APN data manually or request that it be automatically configured by your telecom operator.
Global network reset is the “heavy artillery” for solving software connection errors, which eliminates driver conflicts and incorrect IP configurations.
The specifics of the reset on different versions of Android
The operating system interface Android is undergoing significant changes with every major update. What worked on version 10 or 11 may be hidden in other menus on Android 13 or 14. Google developers strive to unify the user experience, but smartphone manufacturers often make their own adjustments to the menu structure. On “pure” Android, which is used in smartphones
On “pure” Android, which is used in smartphones Google Pixel, Motorola i Nokia, the menu logic is as simple as possible. Here the network settings are placed in a separate subsection of the system. The user sees a clear division between app reset, network reset and full factory reset. It’s quite difficult to make a mistake and delete unnecessary things here thanks to clear labels.
In shells from Chinese manufacturers, such as MIUI (Xiaomi), ColorOS (Oppo) or OriginOS (Vivo), the menu can be more confusing. Often the network reset function is hidden deep in the “Advanced” or “Advanced Settings” sections. In some cases, manufacturers add their own proprietary utilities for network optimization, which may conflict with standard reset methods.
Features of older versions of Android
On Android versions 6-8, the network reset function might not be available as a separate item. In such cases, users had to use hidden engineering menus or perform a full device reset (Factory Reset), which deleted all data.
Below is a table showing the differences in the paths to the reset menu on popular versions and shells. This will help you quickly navigate the interface of your specific device.
| Version / Shell | Path to the reset menu | Features |
|---|---|---|
| Android 13-14 (Stock) | Settings → System → Reset options | Clear separation of reset types |
| One UI (Samsung) | Settings → General settings → Reset | Separate item “Reset network settings” |
| MIUI (Xiaomi) | Settings → Connection and sharing → Reset Wi-Fi | May require logging into Mi Account |
| Android 9-10 | Settings → System → Advanced → Reset | The interface may vary depending on the brand |
If you cannot find the item you need in the menu, use the built-in search in settings. Just enter the phrase “network reset” or “reset network” into the search bar at the top of the screen. The system itself will highlight the desired section, no matter how deep it is hidden in the menu structure.
Using airplane mode to reboot the module
Sometimes a full reset is an excessive measure, and the problem can be solved by simply rebooting the radio module. This method works similar to unplugging the power cord from the router, but applied to a smartphone. Enabling airplane mode forcibly disables all wireless interfaces, including Wi-Fi, Bluetooth, and cellular.
Activate airplane mode through the notification shade or through settings. Leave the phone in this mode for 10-15 seconds. This time is enough for the operating system to completely stop the services responsible for scanning the airspace and maintaining the connection. Then turn off airplane mode and wait until the phone registers with the operator's network again.
After exiting airplane mode, try connecting to Wi-Fi. Often this simple trick can help you reset a stuck authentication process or update the IP address issued by your router. The method is especially effective if the phone “sees” the network, but hangs endlessly at the “Obtaining an IP address” stage.
If standard switching does not help, you can try a more aggressive option. Turn on Airplane mode, then restart your phone without turning off the mode. After the system is fully booted, disable airplane mode. This double reboot ensures that all temporary files and the network daemon cache are cleared from RAM.
Advanced methods: ADB and engineering menu
For users who are not afraid to work with the command line, it is possible to reset Wi-Fi settings via the debug bridge ADB (Android Debug Bridge). This method requires connecting the smartphone to the computer via a USB cable and having the platform tools package installed on the PC. This is useful in cases where the touch screen is unresponsive or the settings menu is corrupted.
Once you have your device connected and USB debugging enabled, you can enter a command that will forcefully delete all saved Wi-Fi configurations. This action is equivalent to a soft reset through the menu, but is performed at the system level. The command looks like this:
adb shell settings put global wifi_saved_networks ""You can also use the command to completely reset your network settings, although it may not work on all non-rooted versions of Android:
adb shell svc wifi reset⚠️ Warning: Using ADB commands requires caution. Entering commands incorrectly may result in system instability or loss of other important settings. Use this method only if you understand what you are doing.
There is also access to the engineering menu through a set of special codes in the Phone application. Codes like ##4636## open the testing menu, where you can see Wi-Fi usage statistics and force connection tests to run. However, the reset functionality there is limited and depends on the specific chipset of the device (Qualcomm, MediaTek, Exynos).
Codes for the engineering menu
Codes may vary. For MediaTek it often works ##3646633##, for Samsung - #0#. Be careful: changing parameters in the engineering menu may void the warranty.
Diagnostics of common connection errors
Understanding the cause of the failure helps to choose the right treatment method. Errors connecting to Wi-Fi on Android can have a different nature: from an incorrect password to a hardware malfunction of the antenna. The system usually displays a short error message, which many users ignore, although it contains the key to the solution.
The most common error is “Incorrect password”. Even if you are sure of the correctness of the entry, try deleting the network and entering the key again, carefully watching the case of the letters. Often the problem lies in the keyboard layout or Caps Lock mode. It’s also worth checking if the router is using a hidden SSID, which requires manually entering the network name.
Another common problem is “Obtaining an IP address...”, which ends in failure. This indicates that the phone has been successfully authenticated, but the router cannot give it an address on the local network. In this case, changing the type of IP address in the Wi-Fi settings from DHCP to Statichelps. You will need to manually register the IP address, gateway and DNS servers.
- 📶 Weak signal: The phone sees the network, but does not connect due to low signal level. Try to move closer to the router or remove physical barriers.
- 🔒 Authentication error: Occurs when the encryption methods do not match (WPA2/WPA3). Try changing the security type in the router settings.
- 🔄 Cyclic reconnection: The device is constantly connecting and disconnecting. This is often solved by disabling the “Wi-Fi Assist” or “Switch to Mobile Network” function.
If none of the software methods help, and the phone does not see any network even after resetting the settings, there may be a hardware failure. The failure of the antenna module or failure of the Wi-Fi chip requires contacting a service center. In this case, a soft reset is powerless.
Why doesn’t the phone connect to 5 GHz Wi-Fi?
Not all older smartphone models support the 5 GHz band. If your phone was released a few years ago, it may only work in the 2.4 GHz band. Check the technical specifications of your device on the manufacturer's official website.
Is it safe to reset network settings?
Yes, it is absolutely safe for your personal data. Photos, contacts, apps and messages will remain in place. Only Wi-Fi passwords, Bluetooth pairs and mobile access point settings are deleted.
What to do if the mobile data is lost after the reset?
Most likely, the access point (APN) settings have gone wrong. Go to the mobile network settings, find the “Access Points (APN)” item and click the menu (three dots) to select “Restore default settings.”
Is it possible to recover a deleted Wi-Fi password?
Without root access, it is impossible to recover a password deleted from the system. However, if you have access to the router's admin panel, you can view or change the password there. You can also find out the password on another device that is already connected to this network.
Does resetting the network affect the operation of banking applications?
No, resetting network settings does not affect the operation of applications. However, if you use a static IP for a corporate network or specific DNS, you will have to configure them again manually.
