The smartphone refuses to connect to Wi-Fi, endlessly giving an authentication error even after changing the password, because Android continues to use an outdated network profile saved in the system memory. Simply disabling the wireless module does not solve the problem, since the access point configuration remains active and blocks the establishment of a new connection with the current security settings. In order for the gadget to start asking for the correct credentials, you must forcefully delete the saved network entry through the device settings.
The process of deleting a saved profile may differ depending on the version Android and user interface of the manufacturer, such as One UI from Samsung or MIUI from Xiaomi. Despite the visual differences, the logic of action remains the same: access the list of saved networks and select the “Forget” function. This procedure does not affect other phone settings, but effectively solves problems with constant connection disconnections or authentication errors.
In this material we will look at a detailed algorithm of actions for different versions of the operating system. You will learn where to look for the necessary menu items, what to do if the standard method does not work, and what alternative methods exist for clearing the connection list. We will also look at cases when deleting the network is necessary to ensure cybersecurity your device.
Why you need to delete saved WiFi networks
The main reason why you should forget the WiFi network on Android is a configuration conflict. When the router changes the encryption type (for example, from WPA2 to WPA3) or password, the phone may continue to try to connect using the old data. This results in an endless loop of connection attempts, which drains battery power and makes it appear that the communication module is faulty. Deleting a profile forces the system to request new parameters.
Another important reason is security. If you regularly connect to public hotspots in cafes, airports or shopping malls, your smartphone will automatically search for familiar network names (SSIDs). Attackers can create a network with an identical name to intercept your traffic. Regularly clearing the list saved networks minimizes the risk of automatically connecting to compromised nodes.
⚠️ Attention: After performing the “Forget Network” procedure, the phone will completely delete all data about this connection, including the password. The next time you log in, you will have to enter your passkey manually. Make sure you know the current password for the router.
Deleting networks is also useful when moving or changing your place of residence. The list of accumulated connections can become huge, which could theoretically slow down the process of scanning the airwaves on older devices with limited RAM. Clearing the list helps keep the system in order and speeds up the search for available signals in a new location.
Removing the network on pure Android (10, 11, 12, 13, 14)
On smartphones with a “clean” operating system, such as Google Pixel, Moto or Nokia, the settings interface is as standardized as possible. To forget the WiFi network on Android in these versions, you need to go to the wireless connections section. Typically the path looks like this: open Settings, then select Network and Internet or Connections.
Next go to menu Wi-Fi. Here you will see a list of available networks and those to which the phone is currently connected. Find the desired network in the list. If you are currently connected to it, click on the gear icon next to the name. If the network is saved but not active, you may need to click on the menu icon (three dots) or long press on the network name to see the context menu.
In the network properties window that opens, find the Forget or Delete networkbutton. In new versions Android 12 and higher, this option is often highlighted in red or located at the bottom of the screen. After clicking, the system will ask you to confirm the action. Agree, and the profile will be immediately deleted from the device memory.
- 📱 Open settings and go to the Wi-Fi section.
- 🔍 Find the desired network in the list of saved or available ones.
- ⚙️ Click on the gear or hold your finger on the name of the network.
- 🗑️ Select the “Forget” option and confirm the action.
It is worth noting that in some builds Android the delete function is available only for networks to which the device is currently connected moment. If you want to remove a network that you are not connected to right now, you may need to temporarily move closer to the router or use the Add Network feature to manually enter the settings, and then delete it immediately.
If the Forget button is grayed out, try disabling the Random MAC Address feature in the specific network settings. Sometimes this unlocks the profile management menu.
Instructions for shells of Samsung, Xiaomi and Huawei
Smartphone manufacturers often modify the standard interface Androidby adding their own shells. This affects the layout of menu items. For example, in smartphones Samsung with a shell One UI, the path to the desired function may be slightly hidden. You need to go to Settings → Connections → Wi-Fi. A list of networks is displayed here.
Unlike pure Android, in One UI to delete a network you often need to click on the gear icon to the right of the network name, even if you are not connected to it. In the menu that opens, at the very bottom there will be a button Forget. In some older versions of the firmware, you need to click on the three dots in the corner of the screen and select Network management, where you can tick several profiles for mass deletion.
Device users Xiaomi s shell MIUI or HyperOS may also encounter differences. In the list of Wi-Fi networks, you need to click on the arrow next to the name of the access point. This will open a detailed menu, where the button Delete network usually is at the bottom. In devices Huawei with a shell EMUI the procedure is similar: a long press on the network brings up a menu with a delete option.
| Brand / Shell | Path to settings | Action to delete |
|---|---|---|
| Samsung (One UI) | Settings → Connections → Wi-Fi | Click on the gear → Forget |
| Xiaomi (MIUI/HyperOS) | Settings → Wi-Fi | Arrow next to the network → Delete network |
| Huawei (EMUI) | Settings → Wi-Fi | Long press → Delete |
| Google Pixel (Stock) | Settings → Network and Internet → Wi-Fi | Gear → Forget |
If you don’t find the button right away, look around the entire screen, including the bottom and pop-up menus. The manufacturers' logic is aimed at protecting the user from accidental deletion, so the button is often hidden behind an additional tap.
☑️ Check before deleting the network
What to do if the “Forget” button is inactive or missing
Sometimes users are faced with a situation where the option to delete a network is blocked or simply missing from the menu. This can happen for several reasons. One of them is the presence of active profiles device administration. Corporate security policies or parental control applications may prohibit changing network settings.
In this case, you need to check the Security or Biometrics and Security section in your phone settings. Find item Device Administrators or Administrator Applications. If there are active apps there that you don't use or that are blocking changes, try temporarily disabling their permissions. After this, the Forget Network feature should become available.
⚠️ Warning: Disabling administrator rights for enterprise applications may result in the deletion of work data from the phone. Proceed with caution if the device was issued by your employer.
Another reason may be a failure in the system process responsible for the network. In this case, a simple reboot of the smartphone helps. If this does not help, you can try resetting the network settings, which will be discussed in the next section. Also check to see if Airplane mode is enabled, as it often limits Wi-Fi profile management.
If the problem occurs with only one specific network, it may be marked by the system as “favorite” or has a special status due to the use of functions like Wi-Fi Direct or WPS. Try disabling these features in the advanced Wi-Fi settings. In rare cases, it helps to remove updates to the “Settings” system application through the app menu, which will return it to the factory state.
Hidden developer settings
In the “For Developers” menu there is an option “Always turn on mobile data”. Its activation does not affect the deletion of networks, but can help in diagnosing problems switching between Wi-Fi and a mobile network if deleting the profile does not solve the problem of accessing the Internet.
Resetting network settings as a radical solution
If it is not possible to delete a network individually or the problem is widespread (not a single connection works), the most effective solution would be to reset the network settings. This operation will return all Wi-Fi, Bluetooth and mobile data settings to factory defaults. This will not delete your photos, contacts or applications, but will only affect the communication modules.
To perform a reset, go to Settings. Depending on the phone model, find the System, General settings or Advancedsection. Select item Reset or Recovery and reset. In this menu there will be an option Resetting Wi-Fi, mobile data and Bluetooth settings. Click on it and confirm the action.
After the reboot, the phone will be “clean” in terms of network connections. You will have to re-enter your home Wi-Fi password and re-(pair) your Bluetooth headphones or watch. This method is guaranteed to delete all saved profiles, including those that may have been corrupted or blocked by system errors. This is the best way to cure connection glitches.
- 🔄 Go to the system settings to the "Reset" section.
- 📶 Select "Reset network settings" (not to be confused with a complete phone reset!).
- ✅ Confirm the operation by entering a PIN code or graphic key.
- 🔌 After rebooting, reconfigure your Internet connection.
⚠️ Attention: Resetting network settings will delete all saved Wi-Fi passwords and paired Bluetooth devices. Make sure you have access to the passwords for your networks before starting the procedure.
Use this method if standard network deletion did not solve the connection problem. It often happens that system configuration files accumulate errors that cannot be corrected by simply deleting a single profile. A complete reset of the network stack clears the cache and recreates configuration files from scratch.
Resetting network settings is a safe operation that does not affect the user’s personal data (photos, videos, contacts), but deletes all network configurations and passwords.
Removing networks through the engineering menu and ADB (for advanced)
For users with technical knowledge, there are more in-depth methods for managing network profiles. One of these methods is to use debugging ADB (Android Debug Bridge). This method allows you to manage your phone settings from your computer, which is useful if the touch screen does not work correctly or the interface is blocked.
First, you need to enable the “Developer mode” in the phone settings (usually 7 clicks on the build number in the “About phone” section). Then activate USB debugging. Connect your phone to your PC and enter the command to display a list of saved networks. Although there is no direct command to delete a specific network in standard ADB, you can use reset via the command:
adb shell settings put global wifi_saved_networks""However, a more reliable way via ADB is to perform a network settings reset, similar to what is done in the menu:
adb shell pm clear com.android.providers.settingsBe extremely careful when using the command line. Incorrect input may result in system instability. There are also third-party applications in Google Playthat require root access and allow you to edit the file wpa_supplicant.confwhere all data about networks is stored. This makes it possible to manually cut out lines with unnecessary SSIDs, but requires high qualifications.
Such methods are not recommended for the average user, since the risk of damaging the software is too great. Standard interface tools are sufficient to solve 99% of problems. You should resort to ADB only in exceptional cases when the phone does not boot normally or the sensor does not respond.
Configuration file
On devices with root access, the file with saved networks is located at /data/misc/wifi/wpa_supplicant.conf. Editing it allows you to delete any network, even the system one, but requires a restart of the Wi-Fi service.
Frequent questions and problems when deleting WiFi
Why does the phone automatically connect to the old network after deletion?
If after deletion the network appears again, it may be saved in a cloud account Google and synchronizes back to the device. Check your sync settings under Google → Settings for apps → Wi-Fi. This can also happen if you have a smart watch or tablet on the same account that broadcast saved networks to your phone.
Is it possible to delete a network that I am not currently connected to and which is far away?
Yes, in most modern versions Android you can delete any saved network from the list, even if it is not detected on the air at the moment moment. Just find it in the “Saved networks” list or in the general list (sometimes you need to click “Advanced” or “Manage networks”), click on settings and select “Forget.”
Does deleting a network reset the IP address?
Yes, when you reconnect, the phone will request a new IP address from the router's DHCP server. If you have manually configured a static IP address in the properties of this network, these settings will also be deleted along with the profile, and you will have to enter them again.
How to delete all WiFi networks at once without resetting the settings?
With standard Android tools, you cannot delete absolutely all networks with one button without performing a complete “Reset Network Settings”. You need to remove them one by one. However, on some custom firmware or through root access, you can clear the configuration file, which is equivalent to deleting all profiles.
Does deleting a network affect Internet speed?
Deleting a network in itself does not increase Internet speed. However, if the phone stops trying to connect to a weak or problematic network, it will quickly switch to the mobile data or another stable access point, which will subjectively improve the quality of communication.
