Are you experiencing a problem where your laptop's Wi-Fi suddenly stops working, and the list of networks shows nothing but empty access points? The cause may not be in the drivers or Windows settings, but rather in a hardware-based module being disabled via BIOS/UEFIThis feature is often used in corporate devices to enhance security or is accidentally activated during a factory reset.
Unlike software disabling (when the module is visible in the system but doesn't connect to networks), hardware blocking makes the adapter completely "invisible" to the operating system. In this article, we'll discuss how to check the module's status in the BIOS and enable it on laptops of different brands (ASUS, HP, Lenovo, Dell etc.), as well as what to do if the required option is not in the menu. Important: On some business class models (for example, HP EliteBook or Dell Latitude) Wi-Fi may be blocked by a BIOS administrator password - without it, activation is impossible.
Before messing with BIOS settings, make sure the problem is with the BIOS. Here are the key signs of a hardware shutdown:
- 🔍 In
Device ManagerThere is no "Network adapters" section or the Wi-Fi module is marked as "unidentified device". - 🔌 The physical Wi-Fi button/switch on the laptop body does not respond (if there is one).
- 🖥️ In
Networks and Internet → Wi-Fi(Windows) There is no power slider or the message "No networks available" appears. - 🔧 Teams
ipconfig /allornetsh wlan show interfacesVCMDdo not show wireless adapter.
1. How to enter BIOS/UEFI on a laptop
To enable the Wi-Fi module through the BIOS, you first need to access it. The entry method depends on the manufacturer and age of the device. On modern laptops (post-2018), UEFI - graphical interface with mouse support, on older ones - text-based BIOS.
Here is the universal algorithm:
- Turn off your laptop completely (do not restart!).
- Press the power button and continuously press the BIOS entry key (See table below). On some models you need to hold
Fn+ key. - If the Windows logo appears, reboot and try again.
