Wireless connection failures are one of the most common problems faced by smartphone users. The device may not see the router, constantly lose the signal, or give an error when obtaining an IP address. In such situations, standard reboot methods do not always help, and deeper intervention in the system configuration is required. Resetting WiFi settings on Android allows you to clear the network services cache and return the module to its original state.
The procedure for resetting connection parameters may vary depending on the version of the operating system and the manufacturer's shell. In some cases it’s enough to simply forget one network, while in other cases you will need to completely reset all network settings, including Bluetooth and mobile data. It's important to understand the difference between these steps so you don't lose critical data or access to other services. In this article, we will analyze in detail all the available methods for restoring the functionality of the wireless module.
Diagnostics of problems with a wireless connection
Before resorting to radical measures, you need to make sure that the problem really lies in the smartphone settings, and not in the provider’s equipment or router. Often, users try to reset their phone when the router is simply frozen or has lost connection with the external network. The first step should always be to check the functionality of other devices on the same network. If the laptop or tablet also does not have access to the Internet, the problem is global.
If other gadgets work stably, but your Androidsmartphone behaves incorrectly, you should pay attention to specific symptoms. For example, the phone may see the network, but refuse to connect, or the connection is established, but data is not transferred. In some cases, simply switching the flight mode helps, which restarts the radio modules. However, in case of driver software failures or configuration file conflicts, a more serious approach is required.
⚠️ Attention: Before performing any reset actions, make sure you know the password for your WiFi network. After clearing the settings, the device will forget all saved access points, and you will need to enter the security key again.
It is also worth checking if the device has a power saving mode enabled, which can aggressively turn off WiFi in the background. Sometimes the problem can be solved by simply updating the phone's firmware, as manufacturers regularly release patches to fix vulnerabilities in the network stack. If the software is up to date, but the problems persist, we move on to methods for clearing the configuration.
First try simply rebooting the router by disconnecting it from the power supply for 10-15 seconds. In 70% of cases, this solves the problem without having to touch the phone settings.
Deleting a saved network and clearing the cache
The most gentle method of solving connection problems is deleting a specific problematic network from the device’s memory. This method does not affect other system parameters and allows you to isolate an error associated with a change in router settings or a conflict in encryption keys. To do this, you need to go to the settings menu and find the section responsible for wireless connections. The interface may differ on different models, but the logic of action remains the same.
Find in the list of available networks the one that you cannot connect to or the one that is causing failures. Click on it and select the “Forget” or “Delete network” option. This action will erase the saved password and IP settings for this access point. After this, try searching for networks again and connecting by entering the current data. This often solves the problem if the router has changed the broadcast channel or encryption type.
Deeper cleaning concerns the system cache of network services. In older versions of Android, it was possible to clear the cache of a specific system application through the app menu, but in modern shells this option is often hidden or removed. However, removing the network is an effective analogue. If the problem is widespread and affects all available access points, you may need to reset all network settings of the device entirely.

Full reset of network settings on Android
If deleting one network did not help, the next step is to completely reset the network settings. This feature returns all settings related to Internet connection and peripheral devices to factory defaults. It's important to note that this process does not delete your personal files, photos, or installed applications. It affects only the configuration of communication modules.
To perform this operation, you must go to the deep system settings menu. The path may look different: on pure Android this is usually partition System → Reset settings, and on Samsung or Xiaomi devices the path may lie through General settings or Additional. Find the item called “Reset Wi-Fi, mobile data and Bluetooth settings.” The system will warn you about the consequences of this action.
After confirming the operation, the phone will reboot the network interfaces. All saved WiFi passwords will be deleted, pairings with Bluetooth headsets and watches will be severed, and mobile hotspot and APN settings will return to default. This is an effective way to deal with software glitches when the phone “thinks it is connected, but data is not transferred, or when the WiFi module is unstable.
☑️ Preparing to reset the network
⚠️ Attention: After resetting the network settings, you will have to re-pair all Bluetooth devices (headphones, speakers, smartwatches). Make sure that you have access to them for re-configuration.
Reset features on different versions of Android
The interface and menu layout have changed significantly with the release of new versions of the operating system. Users of older devices running Android 9 Pie or Android 10 may require a different algorithm of actions compared to owners of modern gadgets running Android 13 or 14. Understanding these differences will help you quickly find the right option and not wander through the menu in vain.
On devices running Android 10 and lower, the reset option was often located in the section "Backup and reset." There you could choose a single reset for WiFi only or a general reset for all networks. Starting from Android 11Google has unified this process, placing it in a separate sub-item of the reset menu, which clearly indicates what data will be affected. In new shells, such as One UI from Samsung or MIUI from Xiaomi, developers often add their own proprietary diagnostic utilities.
Owners of Xiaomi smartphones should pay attention to the “Security” or “Services and Feedback” application, where sometimes there are tools for resetting network settings without entering the deep system menu. On Pixel and Motorola phones, the path is as standardized as possible and follows Google's reference design. If you cannot find the item you need, use the search in the settings by entering the query “reset” or “reset”.

Hidden engineering menus
On some devices you can enter the code ##4636## in the dialer to get to the testing menu. There, in the “Wi-Fi Information” tab, there is a “Wi-Fi Smart Lock” button or radio restart options, but they should be used with caution.
Reset via the engineering menu and ADB (for advanced)
For users with technical knowledge, there are more powerful tools for managing network parameters. The engineering menu or using USB debugging (ADB) allows you to execute commands that are not available through the standard GUI. These methods are useful when a standard reset does not work due to damage to system files or blocking by malware.
Using the ADB console requires connecting the phone to the computer and installing drivers. After enabling USB debugging in the Developer Options menu, you can send a command to delete all network configurations. This action is equivalent to a factory reset of the network subsystem, but is performed at the command line level. This approach is often used by service center specialists during software repairs.
adb shell settings delete global wifi_configured_networksadb shell svc wifi disable
adb shell svc wifi enable
The first command in the example above deletes the list of saved networks from the global settings database. Subsequent commands forcefully turn off and on the WiFi module, initiating a complete reboot at the kernel level. Be extremely careful when entering commands: an error can lead to unstable operation of other system components. This method is not recommended for ordinary users without understanding the consequences.
Using ADB commands allows you to bypass graphical interface errors when the reset button in the menu is not pressed or the cleaning process freezes.
What to do if the reset did not help
There are situations when even a complete reset of the network settings does not restore WiFi functionality module. In this case, the problem is most likely hardware in nature or related to deep damage to the firmware. If after resetting the phone does not see any network at all, or the WiFi button is inactive (gray), this is an alarming symptom.
It is worth checking whether the device is in safe mode, which could have been activated accidentally during boot. In this mode, third-party applications are disabled, and if WiFi starts working, it means that the problem was caused by some installed application (for example, an antivirus or traffic manager). It is also possible for the antenna cable to physically come off inside the case after a fall or impact.
If software methods have been exhausted, the only solution is to reflash the device or contact a service center. Sometimes resetting the entire phone to factory settings (Hard Reset) helps, but this is an extreme measure and requires a full data backup. You should not ignore signs of hardware failure, as further operation may lead to complete failure of the communication module.
⚠️ Attention: If the WiFi module gets hot or the phone quickly discharges when you try to turn on the wireless network, immediately stop trying to connect. This may indicate a short circuit in the antenna power circuit.
Frequently asked questions (FAQ)
Will my browser history be deleted when resetting the network settings?
No, resetting the network settings only affects connection settings (Wi-Fi, Bluetooth, mobile networks). Browsing history, bookmarks, saved browser passwords and personal files will remain in place. Only passwords from WiFi networks saved in the system are deleted.
Do you need to remove the SIM card before resetting?
It is not necessary to remove the SIM card; the procedure for resetting network settings is safe for it. However, the access point settings (APN) for mobile data will return to factory settings. If you have specific settings from your operator, you will have to enter them manually after the reset.
Why does not the phone see 5 GHz WiFi after the reset?
Perhaps your router is configured for a specific channel or standard that the phone does not support by default after the reset. Try changing the router settings, setting the channel width to 20/40/80 MHz automatically, or update the WiFi drivers on your phone if a system update is available.
Is it possible to recover deleted WiFi passwords?
Without root access, it is impossible to recover deleted system passwords. If you have access to a Google account and synchronization is enabled, some passwords may have been saved in the Google cloud and restored after logging into your account, but this depends on the version of Android and synchronization settings.
Does this function reset VPN settings?
Yes, resetting network settings deletes all created VPN profiles and proxy server settings. You will have to set up VPN connections again by importing configuration files or entering data manually.
