If your Galaxy S25 Ultra keeps forgetting Wi-Fi passwords, reconnecting to the same network again and again can be annoying. This issue usually happens because of corrupted network settings, outdated software, or certain power-saving options interfering with Wi-Fi storage. Fortunately, there are several ways to fix it.
Why Your Galaxy S25 Ultra Won’t Save Wi-Fi Passwords
- Corrupted Wi-Fi or network settings.
- Battery optimization limiting background network activity.
- Outdated software or firmware version.
- Improper synchronization with your Samsung or Google account.
- Wi-Fi router issues causing reauthentication requests.
Forget and Reconnect to the Network.
Sometimes, the stored Wi-Fi data may be corrupted, preventing your phone from saving passwords correctly. Reconnecting helps reset the connection.
- Open Settings, and then tap Connections.
- Tap Wi-Fi, and then tap the gear icon next to your network.
- Tap Forget, and then reconnect by entering your Wi-Fi password again.
This refreshes the stored network information and fixes temporary connection errors.
Check Auto Reconnect Option.
If Auto reconnect is disabled, your Galaxy S25 Ultra may not remember saved networks.
- Open Settings, and then tap Connections.
- Tap Wi-Fi, and then select your preferred network.
- Make sure Auto reconnect is toggled on.
This ensures your device automatically connects to known networks without re-entering credentials.
Disable Battery Optimization for Wi-Fi.
Power-saving settings may restrict Wi-Fi background services, causing the phone to forget network details.
- Open Settings, and then tap Battery and device care.
- Tap Battery, and then tap Background usage limits.
- Disable any restrictions for system apps like Wi-Fi or Android System.
This allows the system to store and recall saved Wi-Fi credentials properly.
Reset Network Settings.
If none of the above works, resetting network settings will clear corrupted configurations related to Wi-Fi, Bluetooth, and mobile networks.
- Open Settings, and then tap General management.
- Tap Reset, and then tap Reset network settings.
- Confirm the action and wait for the device to restart.
After restarting, reconnect to your Wi-Fi network and re-enter your password. The issue should now be resolved.
Update Software.
Outdated firmware or software bugs can cause inconsistent Wi-Fi behavior. Keeping your Galaxy S25 Ultra up to date ensures better stability.
- Open Settings, and then tap Software update.
- Tap Download and install.
- If an update is available, follow the on-screen instructions.
Once installed, restart your phone and check if it now saves Wi-Fi passwords correctly.
Your Galaxy S25 Ultra should now remember Wi-Fi networks as expected. Regular software updates and occasional network resets can help prevent this issue from returning.
FAQs
Why does my Galaxy S25 Ultra forget Wi-Fi networks after reboot?
This usually happens due to corrupted network cache or sync errors with your Samsung or Google account. Resetting network settings usually resolves it.
Will resetting network settings delete my data?
No. It only clears saved Wi-Fi, Bluetooth, and mobile network configurations. Your photos, apps, and personal files remain safe.
Can a router cause Wi-Fi password issues?
Yes. If your router uses frequent password renewals or device filtering, it can force your phone to reauthenticate. Rebooting the router or disabling MAC filtering can help.
