    • Expand the "Network adapters" category.
    • Right-click on your WiFi adapter (it will likely include the words "Wireless" or "WiFi" in its name) and select "Update driver."
    • Choose "Search automatically for drivers." Windows will search for the latest driver on your system and online. If an update is found, it will be installed automatically. Device Manager provides a direct way to update drivers. If Windows finds an updated driver, it will download and install it automatically. If no update is found, you can try searching for drivers on Windows Update or manually downloading them from the Lenovo website. Keeping your drivers up-to-date is crucial for optimal performance and stability.

  2. Update via Windows Update: Windows Update can also provide driver updates, including those for your WiFi adapter. To check for updates, follow these steps:

    • Press Windows key + I to open the Settings app.
    • Click on "Update & Security."
    • Click on "Check for updates." Windows will scan for available updates, including driver updates. If any WiFi driver updates are found, they will be downloaded and installed automatically. Regularly checking for updates through Windows Update is recommended to ensure your system has the latest drivers and security patches. Driver updates released through Windows Update are thoroughly tested by Microsoft, making them a reliable source for driver updates. This method is often the easiest way to keep your drivers up-to-date.

  3. Download and Install the Driver Manually: If Windows cannot find the latest driver, you can download it manually from the Lenovo website. This is a reliable method to ensure you have the correct driver version for your specific laptop model. To download the driver manually:

    • Visit the Lenovo Support website (https://pcsupport.lenovo.com/).
    • Enter your laptop's model number (Lenovo LOQ 15AIX9 12450HX) or serial number.
    • Navigate to the "Drivers & Software" section.
    • Filter by "Networking: Wireless LAN" to find the WiFi driver.
    • Download the latest driver for your operating system.
    • Once downloaded, run the installer and follow the on-screen instructions. Manually installing the driver ensures that you have the latest version specifically designed for your hardware. This method is particularly useful if you're experiencing compatibility issues with older drivers. Make sure to download the correct driver version for your operating system (e.g., Windows 10 or Windows 11, 64-bit or 32-bit). After installing the driver, restart your laptop to apply the changes.

Step 3: Roll Back the WiFi Driver

If the WiFi issues started after a recent driver update, it's possible that the new driver is incompatible or buggy. In this case, rolling back to the previous driver version can resolve the problem. To roll back the WiFi driver, follow these steps:

  • Press Windows key + X and select "Device Manager."
  • Expand the "Network adapters" category.
  • Right-click on your WiFi adapter and select "Properties."
  • Go to the "Driver" tab.
  • If the "Roll Back Driver" button is enabled, click it. If the button is grayed out, it means there is no previous driver version to roll back to. Rolling back to a previous driver version can often resolve issues caused by a faulty update. The "Roll Back Driver" button will only be enabled if there is a previous driver version available. If you roll back the driver and the issue is resolved, you can choose to temporarily prevent Windows from automatically updating the driver to avoid the problem from recurring. This can be done through the Group Policy Editor or by using a driver update management tool.
  • Follow the on-screen instructions to complete the rollback process.

Step 4: Uninstall and Reinstall the WiFi Driver

If updating or rolling back the driver doesn't work, try uninstalling and reinstalling the WiFi driver. This process completely removes the driver from your system and then reinstalls it, which can resolve more persistent driver issues.

  1. Uninstall the Driver:

    • Press Windows key + X and select "Device Manager."
    • Expand the "Network adapters" category.
    • Right-click on your WiFi adapter and select "Uninstall device."
