When Wi-Fi stops working, the cause may be the PC, the router, the saved network profile, or the internet service. Test the simplest possibilities first so you can tell whether the issue affects one device or the whole network.

Before you start: Save important work and avoid deleting, resetting, or changing anything you do not understand. Software menus can move slightly between versions.

Step-by-step instructions

Step 1: Check Wi-Fi and airplane mode

Make sure Wi-Fi is enabled and airplane mode is off.

Step 2: Test another device

Connect a phone or another computer to the same network. If nothing connects, focus on the router or internet service.

Step 3: Forget and reconnect

Forget the saved Wi-Fi network, reconnect, and enter the password again.

Step 4: Restart the PC

Restarting can clear a stuck network process or finish an update.

Step 5: Restart the router if needed

If several devices are affected, restart the router rather than performing a factory reset.

Step 6: Check Windows Update

Install normal updates and restart if requested.

Useful tips

  • If only one website fails, the problem may be the site or browser rather than Wi-Fi.
  • Move closer to the router to rule out weak signal.
  • Do not factory-reset the router unless you understand the settings that will be lost.

Frequently asked questions

Why does Wi-Fi say connected but no internet?

The PC may be connected to the router while the router itself lacks internet access, or a network configuration issue may be blocking traffic.

Why can my phone connect but my PC cannot?

That points more strongly to a Windows, adapter, driver, or saved-network issue on the PC.

Should I change DNS first?

No. Start with simpler checks before changing network configuration.
