Step by Step
- Open Settings.
- Select Network & internet.
- Select Wi-Fi.
- Open Manage known networks.
- Find the network.
- Select Forget.
- Reconnect later by selecting the network and entering its current password.
If That Doesn't Work
- Forgetting a network removes the saved password from that Windows connection profile.
- This is useful when a saved password or network configuration is wrong.
