Resetting network settings erases all saved Wi-Fi networks and passwords, Bluetooth pairings, and VPN or cellular settings, then returns those to defaults. Your photos, apps, and files are not touched. It is a common fix for Wi-Fi that will not connect, Bluetooth that will not pair, or mobile data that stopped working. After the reset you reconnect to Wi-Fi and re-pair devices.
Why this happens
- It clears saved Wi-Fi names and passwords, so the device forgets every network.
- It removes Bluetooth pairings, so accessories must be paired again.
- It resets VPN, APN, and cellular data settings to factory values.
- This wipes any corrupted network configuration that was causing the fault.
Is this normal?
Yes. It is a safe, widely recommended step when connectivity problems do not respond to restarting the device or the router.
Does it cause any problems?
The only inconvenience is that you must reconnect to every Wi-Fi network with its password and re-pair Bluetooth devices afterward. No personal data or apps are lost.
How to fix or check it
- iPhone: Settings, General, Transfer or Reset iPhone, Reset, Reset Network Settings. Enter your passcode to confirm.
- Android (wording varies by brand): Settings, System, Reset options, Reset Wi-Fi, mobile and Bluetooth. On some phones this sits under General management or Connections.
- Windows: Settings, Network and internet, Advanced network settings, Network reset. This removes and reinstalls your adapters and restarts the PC.
- Mac: there is no single button. Forget the network under Wi-Fi settings, or remove network configurations in System Settings, Network.
- Have your Wi-Fi passwords ready, then reconnect and re-pair devices after the reset.
Frequently asked questions
Will resetting network settings delete my photos or apps?
No. It only affects network related settings. Your photos, apps, messages, and files remain in place.
Do I need my Wi-Fi password afterward?
Yes. Every saved network is forgotten, so you will re-enter Wi-Fi passwords to reconnect.
Does it change my phone number or carrier plan?
No. It resets on-device settings only. Your number, plan, and SIM are not affected.
