You just bought a laptop Lenovo or have you encountered the problem of no internet connection after updating Windows? Turning on Wi-Fi Fixing Wi-Fi issues on devices from this brand may seem like a trivial task, but in practice, users often encounter unexpected complications. From a blocked function key to missing drivers, there are dozens of reasons why Wi-Fi won't work.

In this article we will look at All current methods for turning on Wi-Fi on laptops Lenovo (including models IdeaPad, Legion, ThinkPad And Yoga), regardless of the Windows version. You will learn how to activate a wireless network through hot keys, Windows Settings, device Manager and even BIOSAnd if the problem lies deeper, we'll show you how to diagnose the problem and restore the connection without calling a service center.

Before proceeding with the instructions, please check two key points: whether Wi-Fi is working on other devices (smartphone, tablet) and whether the wireless network indicator on the laptop case is lit. If the indicator does not light up or blinks red — the problem may be in the hardware shutdown of the module.

1. Hotkeys: The fastest way to turn on Wi-Fi

Most laptops Lenovo equipped function key to control wireless modules. This is usually a combination Fn + F5, Fn + F7 or a dedicated key with an antenna icon. However, the combination may vary depending on the model and BIOS version.

How to find the right combination:

• 🔍 Inspect the keys F1-F12 - look for the icon airplane (airplane mode) or antennas.
• 💡 On models ThinkPad a separate key is often used Wireless (located next to Power).
• 🔄 If the combination doesn't work, try pressing Fn + Esc - this locks/unlocks the function keys.

Important! On some laptops (eg. Lenovo Legion Y540) key Fn is disabled by default in the BIOS. In this case, simply press F5/F7 without Fn.

Press Fn + F5 (or F7)

Check the Wi-Fi indicator on the case

If it doesn't work, press Fn + Esc and try again.

Try a key without Fn (for some models)-->

⚠️ Attention: On laptops with Windows 11 The key can turn on not only Wi-Fi, but also Airplane modeIf Bluetooth also disappears after pressing, check the notification panel.

2. Enable Wi-Fi via Windows settings
