Since Ethernet works, the PC has internet access, so focus on the wireless adapter and its driver.
- Check whether the Wi‑Fi adapter appears in Device Manager.
- Open Search and type Device Manager.
- Expand Network adapters.
- If a wireless adapter is listed, uninstall and reinstall it:
- Double-click or right-click the adapter.
- Select Uninstall device.
- If shown, select Delete the driver software for this device or Attempt to remove the driver for this device.
- Restart the PC.
- After restart, Windows should automatically reinstall the adapter driver.
- If no Wi‑Fi adapter is shown or reinstall does not help, install the correct Wi‑Fi driver manually.
- Download the Wi‑Fi/network adapter driver from the PC manufacturer’s website.
- If needed, use another device and copy the driver to a USB flash drive.
- Install the driver, then restart the PC.
- Since Ethernet is available, install Windows updates.
- Open Windows Update and install the latest updates.
- This can also install missing or updated network drivers.
- If the issue started after a recent update and the Wi‑Fi adapter is present, remove and reinstall the driver again after downloading a backup driver first.
- Warning: uninstalling the wrong network driver can temporarily remove connectivity. Keep the correct driver available before removing it.
- If Wi‑Fi still does not appear, try the built-in network troubleshooter.
- On Windows 11, start the automated Network and Internet troubleshooter in the Get Help app.
Because Ethernet works but Wi‑Fi does not appear, the most likely cause is that the wireless adapter driver is missing, not recognized correctly, or needs to be reinstalled.
