What function key turns on wireless capability?

The function key that turns on wireless capability typically varies by laptop manufacturer, but it is often one of the F keys (like F2, F3, or F12) and is usually marked with a wireless symbol or an antenna icon. To activate it, you usually need to hold down the "Fn" key while pressing the corresponding F key. Some laptops might also have a dedicated switch or a combination of keys to toggle wireless functionality. Always refer to your laptop's user manual for specific instructions.
