A white X on the Wi‑Fi/network icon usually means Windows is not connected to the network or internet. Since the adapter worked in the store but not at home, start with the simplest checks and then move to the adapter itself.
- Run the Windows network troubleshooter.
- On Windows 11, start the automated Network and Internet troubleshooter in the Get Help app.
- It can automatically diagnose and fix common connection problems.
- Check that the USB Wi‑Fi adapter is detected and enabled.
- Open Device Manager.
- Expand Network adapters.
- Find the Netgear wireless adapter.
- If it is disabled, right-click it and select Enable device.
- If it is missing entirely, Windows is not detecting it and the driver may need to be installed manually.
- Verify the driver.
- In Device Manager, right-click the wireless adapter and select Properties > Driver.
- Check the Driver Version and Driver Date.
- Run Windows Update and compare that with the latest driver offered by the device manufacturer.
- Reinstall the adapter driver if the problem started after an update or the adapter is unstable.
- In Device Manager, expand Network adapters.
- Right-click the adapter and select Uninstall device.
- Check Attempt to remove the driver for this device and select Uninstall.
- Restart the laptop.
- Windows will try to reinstall the driver automatically.
- Before uninstalling, download a backup driver from the PC or adapter manufacturer if possible. If the laptop cannot get online, use another PC and copy the driver to a USB drive.
- Turn off power saving for the Wi‑Fi adapter.
- In Device Manager, right-click the Wi‑Fi adapter and select Properties.
- Open the Power Management tab.
- Clear Allow the computer to turn off this device to save power.
- Check for Windows updates and restart.
- Go to Start > Settings > Windows Update > Check for updates.
- Install available updates, then restart the PC.
- If nothing else works, use Network reset as a last step.
- Go to Start > Settings > Network & internet > Advanced network settings > Network reset.
- Select Reset now > Yes.
- This removes and reinstalls network adapters and resets their settings to default.
- Risk: VPN software or virtual network software may need to be reinstalled afterward, and saved network profiles may change.
If the adapter does not appear in Device Manager even after reconnecting it, Windows is not detecting it, which points to a driver or hardware detection problem rather than just a saved network issue.
