Or has the Wi-Fi icon suddenly disappeared from the system tray, and the internet only works via a cable? This problem is familiar to many users, especially after system updates or factory resets. In 80% of cases, a disabled adapter is to blame, not a hardware failure.

In this article you will find 5 Proven Ways to Turn on Wi-Fi Manually — from simple (hotkeys) to advanced (BIOS settings and command line). We'll explore why the adapter might disconnect on its own, how to check the drivers, and what to do if the system can't detect wireless networks.

• ⌨️ Hot keys: Click Fn + F7 (or F5, F8 — depends on the model). There should be a wireless network icon on the key. If the combination doesn't work, try holding Fn 2–3 seconds.
• 💡 Wi-Fi indicator: There is an LED on the front panel or next to the keyboard with an image of an antenna. If it does not burn or blinking orange - the adapter is physically turned off.

On models Lenovo Legion (For example, Legion 5) instead of function keys there may be a separate button Airplane Mode (Airplane mode) on the side panel. Make sure it's not active—in this mode, all wireless modules are disabled.
