Open Settings → Network & internet → Advanced network settings → Network reset.
Step by Step
- Try restarting the PC and router and forgetting/reconnecting Wi-Fi first.
- Open Settings.
- Select Network & internet.
- Open Advanced network settings.
- Select Network reset.
- Read the warning carefully.
- Choose Reset now only if you are prepared for Windows to reinstall network adapters and reset network settings.
- Restart when prompted.
If That Doesn't Work
- You may need to reconnect to Wi-Fi, reconfigure VPN software, virtual adapters, or other networking settings afterward.
- Use this as a later troubleshooting step, not the first one.
