Background

Many Windows laptop users may experience problems with WiFi functionality suddenly disappearing. Although there are various claims on the Internet, in reality, this problem is usually not caused by a virus. In most cases, the root of the problem is a missing driver or laptop static interference that prevents the wireless card from working properly.

Provisional networking

During the resolution of the WiFi issue, an internet connection is required, try the following:

  • Direct broadband connection using a network cable (LAN direct connection)
  • Connect your phone via USB cable to use USB network sharing
  • Utilize your phone's Bluetooth network sharing feature

prescription

Below is a set of effective solutions that I have personally verified, please try them in order:

Step 1: Reinstall the driver

  1. Download and install LU Master (Note: LU Master has some controversy, but its driver detection feature is really excellent).
  2. Use LU Master's driver detection feature to find the wireless card driver.
  3. Reinstall the detected wireless card driver.

Note: If you don't want to use LU Master, you can visit your laptop brand's official website and download the appropriate driver according to the model number.

If LU Master fails to detect the wireless NIC driver and only finds the wired NIC driver, go ahead and try step two.

Step 2: Release laptop static electricity

  1. Turn on the laptop.
  2. Press and hold the power button for about 20 seconds until you see the keypad or screen blink 2-3 times and force the power off.
  3. Reboot the laptop.

This method helps to release the accumulated static electricity, Often it can solve the problem of the wireless card not being recognized by the system.

Step 3: Re-detect the driver

If step 2 still does not solve the problem:

  1. Run LuMaster's driver detection function again.
  2. At this point it is likely that you will find that the wireless card driver is recognized.
  3. Follow the prompts to install or update the driver.

caveat

  1. When using third-party software such as LU Master, please be careful to guard against possible bundled software.
  2. If the problem persists, you may need to consider a hardware failure, this side of the recommendation to seek professional repair services.
