What should I do if the adapter is not showing up in Device Manager?

If in the section Network adapters No Wi-Fi device, check:

1. Is the adapter turned on? BIOS (chapter Advanced → Onboard Devices).

2. Is it disabled in the power settings (see the next section).

3. Are the drivers installed (download them from the laptop manufacturer’s website).

5. Enabling the adapter via the command line

If the graphical interface does not help, try enabling the adapter via command lineThis method is useful when the system does not "see" network connections or the Device Manager is unavailable.

Open Command Prompt as Administrator (Win + R → enter cmd → Ctrl + Shift + Enter) and execute the commands in order:

netsh interface set interface "Wireless Network Connection" enable
netsh interface show interface

If the first command doesn't work, try this alternative:
