Network glitches—random drops, sluggish browsing, or Bluetooth that won’t pair—often lead users to the Reset network settings option in Android. Unfortunately, that one‑click reset wipes every saved Wi‑Fi network, meaning you have to re‑enter passwords for every home, office, or coffee‑shop hotspot.
This tutorial walks you through a practical workflow that lets you refresh the network stack while preserving all your saved Wi‑Fi credentials. The method combines a quick backup of Wi‑Fi passwords with Android’s built‑in reset, then restores the passwords so you can get back online without typing each one again.
When Android performs a Reset Wi‑Fi, mobile & Bluetooth operation, it deletes the system’s Wi‑Fi configuration database (WifiConfigStore.xml on Android 10+ or wpa_supplicant.conf on older releases). The database holds SSID names, passwords, and other connection parameters. Deleting it is the simplest way for the OS to guarantee a clean state, but it also means every saved network disappears.
If you only need to clear corrupted DHCP leases, reset Bluetooth adapters, or flush cached DNS entries, a full reset is overkill. Unfortunately Android does not expose a granular “reset Wi‑Fi only” button that keeps passwords. The workaround is to back up the password list before the reset, then restore it afterward.
Settings ▶ About phone, tap Build number seven times, then return to Settings ▶ System ▶ Developer options.adb installed if you want to verify that the reset succeeded without reboot loops.wifi_backup_YYYYMMDD.csv in the Downloads folder.Files app → Downloads → locate the CSV file.SSID,Password,Security.Why this matters: The CSV contains the raw passwords in plain text, so treat it like any other credential file—store it securely and delete it after you’re finished restoring.

Settings ▶ System ▶ Reset options. On Samsung phones it may be Settings ▶ General management ▶ Reset.Settings ▶ Network & internet ▶ Wi‑Fi.
What happened: Android deleted the internal Wi‑Fi configuration file, which removed all stored SSIDs and passwords. Mobile data APN settings are also cleared, so you may need to re‑enter carrier details if they do not auto‑populate.
Downloads folder and select the wifi_backup_YYYYMMDD.csv file.WifiManager API, which does not require root.Settings ▶ Network & internet ▶ Wi‑Fi.
Tip: If a particular network fails to reconnect, tap the network name, choose Forget, then manually reconnect using the password shown in the CSV. This forces Android to rewrite the entry with a fresh encryption key.
Because the reset also clears mobile‑data APN entries and paired Bluetooth devices, you should double‑check those areas:
Settings ▶ Network & internet ▶ Mobile network. Most carriers repopulate APN values automatically; if not, open the Access Point Names screen and add the APN details supplied by your carrier.Settings ▶ Connected devices ▶ Bluetooth and re‑pair any devices you use regularly (headsets, car kits, wearables).Some manufacturers (e.g., Xiaomi, Huawei) restrict third‑party apps from reading the Wi‑Fi configuration database. In that case:
Settings ▶ Network & internet ▶ Wi‑Fi, tap a saved network, then tap Share. Scan the QR code with another device or take a screenshot for later entry.READ_WIFI_CREDENTIALS permission, which may be hidden on some OEM skins).Settings ▶ Apps ▶ WiFi Backup & Restore ▶ Storage ▶ Clear cache, then repeat the import.Settings ▶ Network & internet ▶ SIM cards.If you have a computer handy and prefer a command‑line approach, you can copy the Wi‑Fi configuration file before the reset and restore it afterward. This method works on Android 9 and earlier where the file is /data/misc/wifi/wpa_supplicant.conf. On Android 10+ the file is /data/misc/wifi/WifiConfigStore.xml. Both locations require root to read directly, but ADB can pull them if the device is in adb backup mode (no root needed) using the adb backup command with the -apk flag for the com.android.settings package. The steps are more advanced and are provided for power users.
adb installed.adb backup -noapk -nosystem -shared -f wifi_backup.ab com.android.settings. This creates a backup file wifi_backup.ab that contains the Wi‑Fi configuration database.adb restore wifi_backup.ab. During the restore you may be prompted on the device to allow the operation—tap Restore.Note: The adb backup method is deprecated on newer Android releases (Android 12+), and some manufacturers disable it. If the command fails with “Backup failed”, fall back to the CSV method described earlier.
zip -e).By following this step‑by‑step guide you avoid the painful “type every Wi‑Fi password again” scenario while still getting the benefits of a clean network configuration—fewer stale DHCP leases, refreshed Bluetooth pairings, and a reset mobile‑data profile.
Feel free to bookmark this tutorial; the same process works on Android 9 through Android 13, with only minor UI path differences between manufacturers.
