  2. Expand the "Network adapters" branch

Ideally you should see the name of yours there. Wi-Fi adapter (For example, Intel Wireless-AC 9560 or Qualcomm Atheros QCA61x4A). If unknown devices with yellow exclamation marks are displayed instead, there are no drivers. The adapter may also be hidden in the "Other devices" section under a name like PCI Device or Network Controller.

If there is no adapter at all (even with an exclamation mark), this may mean:

  • 🔧 Hardware-based Wi-Fi module disabling (some laptops have a physical switch or key combination)
  • 🛠️ Damage to the module (rare, but it happens after disassembling the laptop)
  • 🖥️ Lack of chipset (motherboard) drivers, which is why the system does not recognize the devices
How to turn on Wi-Fi using a hardware button?

On some laptops (especially Lenovo, HP And Dell older models) there is a physical Wi-Fi switch on the case or a combination of keys (for example, Fn + F2). If the wireless light is not on, try:
