If your vivo X300 Pro keeps forgetting your Wi-Fi password, you probably have to reconnect every time you leave and return home. That gets frustrating fast. The issue usually comes from a small setting, a network glitch, or a software bug that prevents the phone from storing saved credentials properly.
The good news is that this problem is often easy to fix.
Why Your vivo X300 Pro Is Not Saving Wi-Fi Passwords
- Battery optimization is restricting Wi-Fi services.
- The network was saved incorrectly the first time.
- Software glitches after an update.
- Corrupted network settings.
- Router configuration issues.
Restart Your Phone
A restart refreshes background services that manage wireless connections. If the Wi-Fi service failed to store credentials properly, this simple step can reset it.
Press and hold the Power button, and then tap Restart.
Wait for the device to boot up completely, and reconnect to your Wi-Fi network.
Enter the password again and check if it saves this time.
Forget and Reconnect to the Wi-Fi Network
Sometimes the network profile becomes corrupted. Removing it forces the phone to create a fresh connection profile.
Open Settings, and then tap Wi-Fi.
Tap the connected network, and then select Forget network.
Reconnect to the Wi-Fi, enter the password carefully, and tap Connect.
Disable Battery Optimization for Wi-Fi
Aggressive battery management can interfere with background connectivity. This may prevent the phone from maintaining saved network credentials.
Open Settings, and then tap Battery.
Tap Background power management, and locate Wi-Fi related services.
Disable restrictions for Wi-Fi and system connectivity apps.
Reset Network Settings
If the phone still refuses to remember the password, your network configuration may be corrupted. Resetting network settings restores everything to default without deleting personal files.
Open Settings, and then tap System management.
Tap Backup and reset, and then choose Reset network settings.
Confirm the reset, and reconnect to your Wi-Fi network afterward.
Check Your Router Settings
In some cases, the router may have MAC filtering or limited DHCP leases enabled. This can cause repeated authentication issues.
Log in to your router’s admin panel, and check wireless security settings.
Make sure the security type is set to WPA2 or WPA3.
Restart the router, and then reconnect your phone.
If your vivo X300 Pro keeps forgetting Wi-Fi passwords, the issue is usually minor and related to settings or temporary glitches. After refreshing the network profile or resetting network settings, your phone should store the password normally again.
