Test the same Wi-Fi network with a phone or another computer first, because this determines whether to troubleshoot the router/Internet service or only the Windows PC.^1^
If other devices also have no Internet
- Unplug the modem and wireless router from power.
- Wait at least 30 seconds.
- Reconnect the modem first and wait until its lights stabilize.
- Reconnect the router, wait a few minutes, and test again.
- If every device remains offline, check for an outage with your Internet service provider.
Restarting the equipment temporarily disconnects everyone using that network.
If other devices work normally
The issue is limited to the Windows computer. Work through these steps in order:
- Forget and reconnect to Wi-Fi
- Windows 10/11: Settings → Network & Internet → Wi-Fi → Manage known networks.
- Select your network and choose Forget.
- Reconnect and enter the Wi-Fi password.
- Turn off a manual proxy
- Open Settings → Network & Internet → Proxy.
- Turn off Use a proxy server if it is enabled and not required by your organization.
- Reset the Windows network stack
- Search for Command Prompt.
- Select Run as administrator → Yes.
- Run these commands in order:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
Restart the PC afterward. These commands reset TCP/IP and Winsock, request a new address from the router, and clear the DNS cache.^1^
- Check the assigned IP address
- Run
ipconfigin Command Prompt. - Find the Wi-Fi adapter’s IPv4 Address.
- An address beginning with
169.254means Windows did not receive an address from the router. If the network does not intentionally use static addresses, verify that DHCP is enabled in the router’s settings.^1^
- Run
If it still does not connect
Reinstall the Wi-Fi adapter driver:
- On another Internet-connected device, download the correct Wi-Fi driver from the PC manufacturer and save it to a USB drive as a backup.
- On the affected PC, open Device Manager → Network adapters.
- Right-click the Wi-Fi adapter and select Uninstall device.
- Select Attempt to remove the driver for this device, then Uninstall.
- Restart Windows. It should reinstall the adapter automatically; otherwise, install the manufacturer’s backup driver.^1^
Use Network reset only as a final step after the preceding options; Microsoft identifies it as the last troubleshooting measure.^1^
