However, outdated drivers can lead to hardware and software conflicts, ultimately causing them to malfunction.

Updated drivers contain performance and stability patches to reduce vulnerability chances. Therefore, drivers should always be kept updated to prevent such problems. One user on TechGuy reported this problem, and updating drivers eliminated this error for them. As a result, their problem was solved. Follow these steps to install the latest driver successfully:

Reinstall Drivers

Drivers are a means of communication between the I/O device and the Operating System. Uninstalling the drivers will result in a loss of communication between them. Upon reboot, the operating system automatically finds the missing drivers, reinstalls them and configures them accordingly. 

However, the trick here is to leave the system powered off for a while. We have observed multiple users on Microsoft Forums resolve this error when they performed this method. Let us guide you through the process:

  1. Opening Device Manager: Press Win + X > Click on Device Manager.

  5. Turning on the system: Insert battery in case of laptop > Plug in the power cable > Boot the computer.

Disable Network Stack

Network Stack is a feature used to load an operating system from a computer remotely or from a server using a network card. Therefore, if a bootable device is connected to a system and the network stack is enabled, that device will try to boot through the network.

This feature has nothing to do with single-user system configurations. Therefore, it can interrupt the wireless network card when enabled, causing some malfunctions. Turning off this feature helped a few users resolve this error on Dell Forums. Although they explicitly mentioned this method for only Dell models, our research concludes it can also work for other models. To do that:

  1. Restarting system: Press Win + X > Hover over Shut Down or Sign Out > Click Restart.

Reconnect Network Card

Wireless network cards are installed in the mini-PCI slot of the laptop. They are responsible for establishing and maintaining a seamless WiFi connection of your computer to the internet. However, if your Intel Wireless AC 9462 is not working, it may be due to loose antenna wires connected to the network card.

You can reinsert the network card in your system, which may resolve this issue. A user tried and stated this method on Lenovo Forums, and doing this fixed the problem for them. Here’s how you can reconnect your wireless network card:

  1. Powering off system: Shut down your system > Unplug the AC Power cord.
  2. Opening panels: Turn over the laptop > Unscrew all the bottom panels.
