2. Try holding Fn 2-3 seconds before pressing F2.
3. On models with Windows 11 Check if the function keys are disabled in the BIOS settings (section Advanced → Function Key Behavior).

2. Enable Wi-Fi via Windows settings

If the keyboard shortcuts don't work, use the system settings. Windows 10/11 The path to Wi-Fi management is the same, but the interface is slightly different.

If none of the software methods helped, the problem may be in hardwareHere are some signs that your Wi-Fi adapter is faulty:

• 🚫 In Device Manager The adapter displays an error (code 10, 43 or 45).
• 🔌 The Wi-Fi indicator on the laptop body does not light up when pressed Fn + F2.
• 🔧 Reinstalling drivers and resetting the BIOS does not help.
• 💻 The laptop doesn't see it not a single one network, even public ones (in cafes, airports).

• 🔌 The Wi-Fi antenna cable has become disconnected (a common problem after disassembling a laptop).
• 🔥 The adapter burned out due to a power surge.
• 🛠️ Motherboard failure (less common).

What you can do yourself:

1. Carefully disassemble the laptop and check whether the antenna wires are connected to the Wi-Fi module (they are usually black and white).
2. If the adapter is removable (format M.2 or NGFF), try reinstalling it.
