1. Forget a Connected Wi‑Fi Network

  2. Tap the ℹ️ icon next to the network name.

  3. Choose Forget This Network, then confirm by tapping Forget YouTube+15Apple Support+15X (formerly Twitter)+15.

  1. Head to Settings → Wi‑Fi.

  2. Tap Edit (top-right) to view all Known Networks.

  3. Either tap the red minus (–) next to a network and hit Delete, or use the ℹ️ icon → Forget This Network to confirm CNC TeamDynamixSusqu+2Apple Support+2CNC TeamDynamix+2.

To avoid this:

  • Go to Settings → Wi‑Fi.

  • Tap the ℹ️ icon → Auto-Join, and set it to Ask to Join or Never rather than Automatic X (formerly Twitter)+15Susqu+15CNC TeamDynamix+15Apple Support Community+2TechViral+2New York Post+2.

  1. Open Settings → General → Transfer or Reset iPhone.

  2. Tap Reset → Reset Network Settings.

  3. Enter your passcode and confirm.

5. Manage iCloud-Synced Wi‑Fi on Mac

Some users report that, via iCloud Keychain, Wi‑Fi settings linger across devices even after being removed on iPhone Apple Support Community+2Reddit+2New York Post+2HighSpeedInternet.com+4Apple Support Community+4Reddit+4YouTube. If this happens:

  • On a Mac with the same Apple ID and iCloud Keychain active, go to System Settings → Wi‑Fi → Advanced.

  • Remove the unwanted network there and it will sync back to your iPhone.

This can resolve persistent connection issues if the network keeps reappearing.

6. Tackle Managed or Profile-Based Networks

If you can’t forget a network and neither “Forget” nor “Delete” is available, it may be controlled by a mobile device management profile YouTube+2Reddit+2Apple Support+2.

To check:

  • Go to Settings → General → VPN & Device Management.
