Wi-Fi Not Working on Windows 11? A Safe Troubleshooting Guide
When Wi-Fi fails, identify whether the problem affects only your PC or the entire network. This helps avoid unnecessary driver installers and risky changes to router settings.
When Wi-Fi fails, identify whether the problem affects only your PC or the entire network. This helps avoid unnecessary driver installers and risky changes to router settings.
Check the scope of the problem
Start with simple physical and wireless checks.
- Check that Airplane mode is off and Wi-Fi is enabled.
- Try another device on the same network to see whether the router or only your PC is affected.
- Restart the affected PC and router if it is safe and you control the router.
- Move closer to the router and check for a weak signal or interference.
Connected but no internet
A Wi-Fi connection does not guarantee that the ISP connection works.
- Check the internet status on a second device.
- Disconnect and reconnect to the network; re-enter the password only if needed.
- Use Windows Network and Internet diagnostics or the official troubleshooter.
- Ask your network administrator before changing custom DNS, VPN or proxy settings.
Network adapter missing
Drivers or device settings may explain a missing wireless adapter.
- Open Device Manager and look for the network adapter and any error indicator.
- Check Windows Update for approved driver updates.
- For a manufacturer driver, use the laptop or motherboard vendor’s official support page.
- Avoid generic “driver updater” sites and unknown download bundles.
Frequently asked questions
Why does Wi-Fi work on my phone but not my PC?
The fault may be in the PC’s adapter, credentials, driver or settings. Check the adapter and reconnect.
Should I reset all network settings?
Treat a network reset as a later option; it can remove saved network configurations and VPN settings.
Should I download a driver updater?
No. Prefer Windows Update and the manufacturer’s official support page.
Can the PC Helper connect to my router?
No. It only suggests checks; it has no network access to your devices.
Sources and methodology
Steps align with official Microsoft Wi-Fi troubleshooting guidance. Router configurations vary; contact the ISP or network administrator if the problem affects other devices.
