How to recover deleted Wi-Fi on Android: from simple methods to hidden settings

Loss of access to a saved Wi-Fi network on Android is a common problem that occurs after accidentally deleting a network in the settings, resetting to factory settings or system failure. Unlike iOS, where restoring deleted networks often requires a backup, Android provides several ways to get back a lost connection, from the obvious to the obscure. The main difficulty is that the system does not always save passwords in an accessible form, and the standard menus do not offer the “undo deletion” function.

In this article we will examine 5 proven recovery methodsincluding working with system files, backups and hidden settings. It is important to understand that the effectiveness of each method depends on the version Android, device model (for example, Samsung Galaxy, Xiaomi Redmi or Google Pixel) and whether it was performed root access. Some solutions will require technical skills, others just a few clicks in the menu. Let's start with the simplest ones and move on to the advanced ones so that you can choose the best option for your situation.

1. Checking the list of saved networks (without password)

The first thing to do is to make sure that the network is really deleted and not just hidden in the settings. On some devices Android networks remain in the system memory even after clicking "Forget", but are not displayed in the main list.

How to check:

• 📱 Open Settings → Wi-Fi.
• 🔍 Pull the list networks down and hold for 2-3 seconds - some firmware shows hidden networks after this gesture.
• 🔄 Click on the three dots in the upper right corner and select Additional functions or Advanced settings. In some versions there is an item Saved networks.

If the network is displayed, but the connection does not occur, try manually entering the password (if you remember). On devices Samsung s One UI sometimes rebooting the router helps - after that the network may appear in the list again.

2. Restoring via Google backup

If Synchronization with Google accountis enabled on your device, there is a chance that data about Wi-Fi networks is saved in the cloud. This method only works for devices where the function was previously activated Backup in the account settings.

Instructions:

1. Go to Settings → Google → Backup.
2. Make sure the option Data backup is enabled and the last copy has been created before deleting the network.
3. Reset the settings to factory settings (Settings → System → Reset).
4. When setting up the device for the first time, log in to the same account Google and wait for the data to be restored.

⚠️ Attention: This method erases all current data on the device. If the network was recently deleted and the backup is old, the method will not work. Also, on some devices (for example, Xiaomi s MIUI), Wi-Fi backups do not include passwords - only network names.

Make a backup copy of current data (photos, contacts)

Write passwords for important applications

Make sure your Google account is not blocked

Connect the device to charge (reset takes 10-30 minutes)-->

3. Using the file wpa_supplicant.conf (for root users)

On devices with root access (root), Wi-Fi passwords are stored in the system file /data/misc/wifi/WifiConfigStore.xml (on new versions Android) or /data/misc/wifi/wpa_supplicant.conf (on old ones). If you have root, you can extract this file and view saved networks.

Step-by-step guide:

1. Install a file manager with root support (for example, Root Explorer or FX File Explorer).
2. Go to path /data/misc/wifi/ and find the file WifiConfigStore.xml or wpa_supplicant.conf.
3. Copy the file to an SD card or to the cloud.
4. Open it with any text editor (for example, Notepad++ on a PC).
5. Find blocks with tags <string name="SSID"> (network name) and <string name="PreSharedKey"> (password).

🔹 Example file contents:

<WifiConfiguration>
<string name="SSID">MyWiFi_5G</string>
<string name="PreSharedKey">sUp3r$ecr3t!</string>
<int name="Status">2</int>
</WifiConfiguration>

⚠️ Attention: Editing system files without root access or through unverified applications can lead to data loss or locking the device. On devices with Android 10+ the path to the file may differ due to changes in the access control system.

What to do if the file is empty?

If the file wpa_supplicant.conf is empty or missing, this means that the data is stored in encrypted form (starting from Android 9 Pie). In this case, only a backup copy or specialized utilities like WiFi Password Viewer (requires root) will help.

4. Recovery via ADB (without root)

If there is no root access, but the device is enabled USB debugging, you can try to extract network data via Android Debug Bridge (ADB). This method does not work on all firmware, but often helps on devices Samsung, Google Pixel and some models Xiaomi.

Instructions:

1. Install ADB Tools on PC.
2. Connect your phone via USB and enable debugging (in the developer settings).
3. Open the command line and enter:

   adb shell
   su
   cat /data/misc/wifi/WifiConfigStore.xml

4. If the command did not work, try an alternative path:

   adb pull /data/misc/wifi/wpa_supplicant.conf

📌 Important: On Android 11+ access to these files via ADB is often blocked by default. In this case, only root or specialized software like WiFi Key Recovery (requires an unlocked bootloader) will help.

5. Alternative methods: from the router to third-party applications

If none of the above methods worked, less reliable, but sometimes effective options remain:

• 🔄 Rebooting the router: On some router models (for example, TP-Link or ASUS) after rebooting the device automatically connects to the network, even if it was “forgotten” on the phone. Try turning off the router for 30 seconds and turning it on again.
• 📱 Recovery applications: Utilities like WiFi Password Recovery or WiFi Key Viewer promise to show saved passwords, but only work on rooted devices or outdated versions Android (up to 8.0).
• 🖥️ View your password on another device: If on the same network If a laptop or other phone is connected, you can extract the password from there and enter it manually. View the password on another device: The side of the Wi-Fi recovery application often contains or requires unnecessary permissions (access to SMS, contacts). Before installation, check reviews and ratings Windows or another phone, you can extract the password from there and enter it manually.

⚠️ Warning: Third-party Wi-Fi repair apps often contain malicious code or require unnecessary permissions (access to SMS, contacts). Before installing, check the reviews and ratings in Google Play.

What to do if nothing helps?

If all methods have been exhausted, There are two radical options left:

1. Reset network settings: Go to Settings → System → Reset → Reset Wi-Fi, Bluetooth and mobile network settings. This will remove all saved networksbut may solve the connection problem.
2. Contact the network administrator: If we are talking about a work or school network, request a password from the IT department. In some organizations, networks are configured through certificates that cannot be restored independently.

Critical information: On devices with a chip Qualcomm (most flagships Samsung, OnePlus, Xiaomi) after resetting the settings, flashing the module sometimes helps Wi-Fi via QPST or QFil. This method requires deep technical knowledge and is only suitable for experienced users.

FAQ: Frequently asked questions about restoring Wi-Fi on Android

Is it possible to restore a deleted network without root and reset?

Yes, but only if the network is still shown in the list of saved ones (see Section 1) or you have a backup copy in your Google account. On devices without root and without a backup, the chances are minimal.

Why were the networks not restored after resetting the settings?

Resetting network settings (Reset Wi-Fi, Bluetooth and mobile network) deletes all saved networks, not restores them. To get networks back, you need to use Google backup or enter passwords manually.

Does ADB recovery work on Samsung Galaxy S23?

On devices Samsung c Android 13+ access to Wi-Fi files via ADB is blocked by default. To bypass restrictions, root or specialized software is required (for example, Samsung WiFi Password Viewer, but it does not guarantee results).

Is it possible to restore the network if the phone does not turn on?

If the device does not boot (for example, due to a firmware failure), you can only retrieve Wi-Fi data through recovery mode (TWRP) or by connecting the memory to another device. In most cases, this requires disassembling the phone and repair skills.

How to protect Wi-Fi networks from accidental deletion in the future?

To avoid repeated loss of networks:

• 🔒 Disable the option Automatic connection to open networks in the Wi-Fi settings.
• 📝 Keep a list of passwords in a secure manager (for example, Google Password Manager or KeePass).
• 🔄 Create backups regularly copies via Settings → Google → Backup.
