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

Laptops DNS — a popular choice among users due to its price-quality ratio, but sometimes owners face a problem: wireless network Wi-Fi suddenly stops working. The reasons could be various: from an accidental keypress to a driver or settings failure. BIOSIn this article, we'll cover all the possible ways to enable Wi-Fi on laptops. DNS, regardless of the model - be it DNS 15.6" Ultrabook, DNS 14.1" Premium or budget series.

It is important to understand that the algorithm of actions depends on the version Windows (10/11), the state of the hardware switches and even the model Wi-Fi adapterWe'll cover solutions ranging from the simplest (checking the physical button) to the most complex (reinstalling drivers or resetting the BIOS). If you're unsure of the cause of the problem, start with the first section and check each step in turn—this will save you time.

Modern laptops DNS are often equipped with combination adapters (for example, Intel AX200 or Realtek RTL8822CE), which support both Wi-Fi 6, and Bluetooth 5.0If only the wireless network isn't working, but Bluetooth is, the problem is most likely software-related. If both modules are disabled, a hardware switch or BIOS settings are to blame.

1. Checking the physical Wi-Fi switch

The most common reason for Wi-Fi disconnection on laptops DNS — accidental pressing of a hardware button or key combination. The manufacturer often places the switch on the side panel or uses function keys (Fn).

How to check:

• 🔍 Check the sides of your laptop for a slider or button with an antenna icon (📶). On some models DNS (For example, DNS 15.6" Ultrabook 2023) the switch is hidden next to the headphone jack.
• 🎹 Press the combination Fn + F2 (or Fn + F12, depending on the model). The button should have a Wi-Fi icon. After pressing it, check the indicator light—if it lights up blue or white, the module is on.
• 🔄 If the indicator light is flashing orange or not lit at all, proceed to the next section - the problem may be with the drivers.

Attention! On some laptops DNS older than 2021 hardware switch blocks all wireless modules, including Bluetooth. If after activating it, Bluetooth still doesn't work, check the settings in Device Manager.

2. Enable Wi-Fi via Windows settings

If the hardware switch doesn't help, check your settings WindowsWi-Fi often disconnects after a system update or adapter failure. This guide is suitable for Windows 10/11.

Steps to enable:

1. Open Start → Settings (⚙) → Network & Internet.
2. In the section Wi-Fi move the slider to the position "On".
3. If the slider is gray and inactive, click Change adapter settings (bottom right).
4. Find Wireless Network, right click and select Turn on.

If Wi-Fi still doesn't appear after these steps, check the list of available networks. Sometimes the problem lies in hidden networks or incorrect router settings. For example, if your router is in "Display" mode 802.11ax (Wi-Fi 6), and the laptop adapter does not support it, connection will be impossible.

Note: IN Windows 11 The path to the settings may vary. If you don't see the section Wi-Fi, try entering it in the search ms-settings:network-wifi - this will open the desired menu directly.

3. Device Manager: Adapter Diagnostics

If Wi-Fi doesn't turn on through Windows settings, the problem may be adapter driver or its shutdown in Device ManagerThis section is critical for laptops. DNS with adapters Realtek or Meditek, which often conflict with Windows updates.

How to check:

1. Click Win + X and select device Manager.
2. Expand the section Network adapters.
3. Find the device with the names Wireless, Wi-Fi, 802.11 or brand (Intel, Realtek, Qualcomm).
4. If there is an arrow ⬇️ next to the adapter, right-click and select Engage.

If your adapter is marked with an exclamation mark (!), update the driver:

• 🔄 Right-click on the adapter → Update driver → Automatic search.
• 💾 If Windows doesn't find the driver, download it from official DNS website (section "Drivers").
• 🔧 For adapters Intel AX200/AX210 use the utility Intel Driver & Support Assistant.

Critical information: On laptops DNS with adapters Realtek RTL8852AE (found in 2023-2026 models) standard Windows drivers often do not work correctly. In this case Necessarily Install the driver from the manufacturer's website, even if Windows claims that it is "the newest".

What should I do if the adapter is not displayed in the Manager?

If there's no Wi-Fi device listed in the "Network Adapters" section, the issue may be with the BIOS (Section 5) or the module is physically damaged. Try connecting an external USB adapter (e.g., TP-Link TL-WN725N) for diagnostics.

4. Reset network settings

If Wi-Fi turns on but won't connect (or keeps dropping the connection), resetting your network settings will help. This procedure deletes all saved networks and passwords and returns settings to factory defaults.

Instructions for Windows 10/11:

1. Open Start → Settings → Network & Internet → Status.
2. Scroll down and click Network reset.
3. Confirm the action and restart the laptop.

After reset:

• 🔄 Reconnect to Wi-Fi by entering the password.
• 📶 If the network is not displayed, check if the SSID is hidden in the router settings.
• 🔒 If used WPA3, try temporarily switching the router to WPA2 (some adapters DNS do not support the new standard).

Attention! Network reset removes all VPN connections and proxy settings. If you're using a corporate network, save the configuration in advance.

5. Checking BIOS/UEFI settings

On laptops DNS (especially models before 2022) Wi-Fi may be disabled at level BIOSThis happens after a reset, firmware update, or if the user previously manually deactivated the module.

How to enable Wi-Fi in BIOS:

1. Restart your laptop and press Del or F2 (depending on the model) to enter BIOS.
2. Go to the section Advanced or Configuration.
3. Find the parameters:
   • Wireless LAN Support → install Enabled;
   • Onboard Wi-Fi or WLAN → turn on;
   • Radio Control → should be Auto or Enabled.

Save changes (F10) and reboot.

⚠️ Attention! BIOS settings may vary depending on the firmware version. On laptops DNS 2026 and newer is used UEFI with a graphical interface, where Wi-Fi options can be found in the section Wireless Devices.

6. Driver Problems: Deep Diagnostics

If the previous methods did not work, the reason lies in drivers or hardware conflict. Laptops DNS often supplied with adapters Realtek or Intel, which require manual configuration.

Symptoms of driver problems:

• 🚫 Wi-Fi turns on but doesn’t find any networks;
• 🔄 The adapter switches off periodically;
• ⚠️ In Device Manager an error is displayed Code 10 or Code 43.

Solutions:

1. Uninstalling the current driver:
   • Open device Manager → find the adapter → right-click → Remove device.
   • Check the box Remove the driver software for this device (if any).
2. Installing a clean driver:
   • Download the driver from DNS site (Please indicate the exact laptop model!).
   • Unzip the archive and run the installation as administrator.

Driver rollback:

• IN Device Manager select Adapter Properties → Driver → Roll Back Driver.

⚠️ Attention! On laptops DNS with adapters Meditek MT7921 (found in 2026 models) standard drivers from Microsoft cause conflicts. Use only drivers from the official website, even if Windows offers to "update".

7. Alternative connection methods

If you turn on Wi-Fi on your laptop DNS If this doesn't work, consider temporary solutions:

• 📱 USB tethering: Share the Internet from your smartphone (Android/iPhone) via a USB cable. Turn on the phone Modem mode, and on the laptop select USB connection.
• 🔌 USB Wi-Fi adapter: connect an external adapter (for example, TP-Link TL-WN823N). It will bypass problems with the built-in module.
• 🌐 Ethernet: If there is a router nearby, connect to it via cable RJ-45 (even if you haven’t used wired internet before).

If the laptop doesn't see not a single one network (including mobile hotspot), the problem may be in Wi-Fi antennasIn this case, the device must be disassembled to check the cable connections to the adapter. For models DNS with a detachable body (for example, series Premium) You can do this yourself, but it is better to contact a service center.

8. Frequently Asked Questions (FAQ)
