How to Enable Wi-Fi on a Laptop with DNS: 5 Working Methods (2026)

You bought a laptop DNS (or you've been using it for a long time), but it suddenly stopped working Wi-Fi? Or is the wireless network module disabled at the factory, and you don't know how to activate it? This problem is familiar to many owners of budget and gaming models of the brand—from DNS Airbook to DNS PrestigioThe reasons may vary, from a simple settings error to a hardware failure.

In this article we will look at all possible ways to turn on Wi-Fi on laptops DNS, regardless of model and version Windows (10/11) You will learn how to check the adapter status, update drivers, and use hot keys and even go into BIOS, if the module is disabled at the hardware level. And if the problem goes deeper, we'll provide a diagnostic checklist.

Spoiler: in 80% of cases, it's the fault of software settings, not a broken adapter. So don't rush to take your laptop to a service center!

1. Checking the physical activation of Wi-Fi (hot keys and switches)

The first thing to do is to make sure that The Wi-Fi module is physically turned onOn laptops DNS (as with most others) this is the responsibility of:

• 🔑 Key combination - usually Fn + F2, Fn + F12 or a separate button with an antenna icon (depending on the model). The button may have a picture drawn on it. airplane or signal waves.
• 🔄 Hardware switch - on some models (for example, DNS Airbook 15) There is a small slider on the right or front of the case. If it is moved to the position OFF, Wi-Fi will not work.
• 💡 Indicator — the LED with the Wi-Fi icon on the front panel or next to the keyboard should be lit (or blinking). If it does not glow, the module is disabled.

Press a key combination (eg. Fn + F2) and wait 5-10 seconds – a network signal should appear. If nothing happens:

• Try holding Fn longer (sometimes laptops DNS "they don't catch" a short press).
• Check if the key is locked Fn - some models have a separate button Fn Lock.
• Connect your laptop to a charger—some models turn off Wi-Fi when the battery level is low.

⚠️ Attention: On laptops DNS With dual OS (Windows + Linux) Hotkeys may only work on one system. If you recently reinstalled the OS, check the settings in BIOS (chapter Advanced → Hotkey Mode).

2. Enabling Wi-Fi through Windows settings (if the adapter is disabled software-based)

If physically turning it on doesn't help, check your settings. Windows. Often the adapter is disconnected accidentally through Network and Sharing Center or device Manager.
