Resetting network settings is one of the most effective troubleshooting steps for WiFi, Bluetooth, and cellular issues — and one of the most misunderstood. People either avoid it (fearing data loss) or overuse it (resetting before trying simpler steps). Here is what it actually does and when it is the right move.
What changed in 2026
- iOS 17+ and Android 15 both separate "Reset Network Settings" more clearly from factory reset in the UI, making it less scary to find and use.
- Windows 11 24H2 added a more thorough Network Reset that reinstalls all network adapter drivers — helpful for WiFi 7 adapter issues that a simple settings wipe did not fix.
- Saved WiFi credentials now sync via iCloud / Google account on Apple and Android — after a reset, many networks re-authenticate automatically if you are signed in.
- Matter and Thread devices do not use phone WiFi settings for their own connection, so a network reset does not affect smart home device pairing.
What resets — and what does not
| What IS wiped |
What is NOT wiped |
| Saved WiFi networks and passwords |
Photos, videos, music |
| Bluetooth paired devices |
Apps and app data |
| VPN configurations |
Contacts and messages |
| APN and cellular settings |
Accounts and email |
| Custom DNS settings |
System apps and updates |
| Network-specific TLS certificates |
Location settings |
This is not a factory reset. Your data is safe.
When to use network reset
Use it when:
- WiFi connects but shows "No Internet" or limited connectivity
- Bluetooth devices fail to pair or constantly disconnect after a software update
- VPN profiles are corrupted or causing conflicts
- Cellular data works but WiFi does not (or vice versa)
- After a major OS update broke network behavior
- The device shows a saved network but will not connect to it
Do not use it as a first step. Try these first: airplane mode toggle, forget and re-add the specific network, restart router, restart phone.
iPhone / iPad
iOS 17+:
- Settings → General → Transfer or Reset iPhone → Reset.
- Tap Reset Network Settings.
- Enter your passcode.
- Confirm. The phone restarts in ~30 seconds.
- Re-join WiFi networks and re-pair Bluetooth devices.
What iCloud restores automatically: if your iCloud Keychain is enabled, saved WiFi passwords may re-populate for networks other iCloud devices have joined. Bluetooth still needs manual re-pairing.
Android (Google Pixel / stock Android)
Android 13–15:
- Settings → System → Reset options → Reset Wi-Fi, mobile & Bluetooth.
- Tap Reset settings.
- Confirm. No restart required on most devices; settings are wiped immediately.
Samsung Galaxy (One UI 7):
- Settings → General management → Reset → Reset network settings.
- Tap Reset settings → confirm with PIN/pattern.
Windows 11
Option A — Network Reset (recommended for persistent issues):
- Settings → System → Troubleshoot → Other troubleshooters → Internet Connections (run this first).
- If that fails: Settings → Network & Internet → Advanced network settings → Network Reset.
- Click Reset now. Windows reinstalls all network adapters and resets Winsock, TCP/IP, and DNS settings.
- PC restarts automatically. Reinstall VPN clients and any custom network software after.
Option B — netsh commands (manual, granular):
netsh winsock reset
netsh int ip reset
ipconfig /flushdns
ipconfig /release
ipconfig /renew
Run as Administrator in Command Prompt. Restart after.
macOS
macOS does not have a single "Reset Network Settings" button. The equivalent steps:
- System Settings → Network → select each interface (WiFi, Ethernet) → click the minus (–) button to remove it.
- Re-add WiFi: click + → Interface: Wi-Fi → Create.
- To clear DNS cache: open Terminal and run
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder.
- To remove Bluetooth pairings: System Settings → Bluetooth → right-click each device → Remove.
For a deeper reset on macOS: delete /Library/Preferences/SystemConfiguration/ files (com.apple.network.identification.plist, com.apple.wifi.message-tracer.plist) and restart.
Common mistakes
Not noting your WiFi passwords first. Write them down before you reset — you will need them immediately after.
Resetting as a first step. Always try airplane-mode toggle → forget/re-add the specific network → router restart first. Save network reset for when those fail.
Forgetting VPN apps need reconfiguration. VPN profiles are deleted. Open your VPN app after reset and sign in / import the config file again.
Expecting cellular issues to be fixed by network reset on a carrier-locked issue. If SIM-related, call your carrier — APN settings will be restored but a carrier lock or account issue will not be affected.
What to skip
- Third-party "network optimizer" apps claiming to reset settings — they either do nothing or call the same OS API you can access yourself.
- Full factory reset before trying network reset — in the vast majority of cases, network reset alone resolves connectivity problems.
- Removing and reinserting the SIM as a WiFi fix — this addresses cellular, not WiFi.
FAQ
Will I lose my photos if I reset network settings?
No. Network reset only wipes connectivity configurations. Photos, contacts, apps, and all personal data are untouched.
My WiFi still does not work after the reset. What next?
Test on a different network. If it works elsewhere, the issue is with your router (try a router restart or factory reset). If it fails on all networks, suspect a hardware fault or software conflict and consider a full OS restore.
How often can I safely do a network reset?
As often as needed — there is no harm in doing it multiple times. The annoyance is re-entering credentials, not any device risk.
Does network reset remove two-factor authentication apps?
No. 2FA apps (Google Authenticator, Authy) are app data, not network settings. They are unaffected.
