Network reset is a useful last software step, but it removes saved networks and adapter settings, so use it after targeted tests.
What network reset does
The Windows network reset removes and reinstalls network adapters and returns networking components to their defaults. Afterwards the PC behaves as if networking were newly set up.
What you may lose
Saved Wi-Fi networks and passwords are forgotten, custom DNS and static IP settings return to defaults, and VPN clients or virtual adapters may need to be set up again. Write down any settings you rely on before running it.
- Saved wireless networks and passwords.
- Static IP and custom DNS settings.
- VPN profiles and virtual switch adapters in some configurations.
When it is appropriate
Consider it when several targeted checks have failed, the router and other devices are fine, the problem is limited to this PC, and the evidence suggests a damaged network stack, such as repeated adapter errors after software changes.
Do not use it as a first response. If other devices are also offline, a reset on this PC cannot fix it.
After the reset
Reconnect to your network, test the original symptom, and reinstall or reconfigure any VPN or custom settings one at a time so you can see which one reintroduces the fault.
Frequently asked questions
Will a network reset delete my files?
No. It affects networking settings and adapters, not personal files or installed programs, though VPN software may need reconfiguring.
