How to find and set up Wi-Fi on a laptop (DNS): a complete guide

Laptops of the brand DNS (including popular models DEXP, Irbis, Tornado and others) often come with a pre-installed operating system Windows 10/11, where wireless network management is integrated into the default settings. However, many users encounter difficulties when connecting to Wi-Fi for the first time: they can't find the list of available networks, don't understand why the adapter is disabled, or encounter errors like "No connections available".

In this article, we'll look at all the possible ways to find and activate Wi-Fi on a laptop. DNS — from basic methods via the taskbar to manual driver configuration and hardware diagnostics. We'll pay special attention to typical errors that arise due to the specifics of budget models (for example, a network adapter disabled by default or missing drivers after reinstalling Windows).

If your laptop can't detect the network, but Wi-Fi works reliably on other devices, the problem almost certainly lies with the laptop's settings, not the router's. Let's walk through the diagnostics step by step.

1. Quickly search for Wi-Fi via the taskbar

The most obvious way is to use the network icon in the lower right corner of the screen. On laptops DNS it may look like:

• 🌐 — Connect to a network (if Wi-Fi is active and there are saved networks)
• 🔴 — no connection (the adapter is turned on, but there is no connection)
• ❌ — the adapter is disabled or there are no drivers

If there is no icon at all, this is a sign of problems with the drivers or a hardware malfunction (more about this in in the section about drivers). To open the list of networks:

1. Click on the network icon in the taskbar (next to the clock).
2. If there is no icon, click Win + Ato open the notification center, then click on the tile "Net".
3. From the list of available networks, select yours and enter the password.

If the networks are not displayed, but the icon shows that the adapter is enabled (For example, the blue indicator on the laptop case is on), try updating the list manually:

Click the arrow ↻ next to "Wi-Fi" in the notification bar.

2. Check the status of your Wi-Fi adapter in Windows Settings

If the quick method doesn't work, let's move on to manual settings. Open Windows Settings (Win + I) and select a section Network and Internet → Wi-FiThere are three key parameters to check here:

• 🔄 Adapter status: the slider must be enabled "Wi-Fi".
• 📡 Network visibility: if option Hide Networks active - turn it off.
• ⚙️ Equipment settings: click "Managing Known Networks"to remove old connections that may conflict.

Please note the point WLAN AutoConfig Service (tab Additional network settings). If it's disabled, enable it and restart your laptop. This service is responsible for automatically connecting to saved networks.

3. Diagnosing and installing Wi-Fi drivers

About 60% of Wi-Fi problems occur on laptops. DNS Issues related to missing or incorrectly functioning drivers. This is especially true after reinstalling Windows or updating the system. To check the driver:

1. Open device Manager (Win + X → Device Manager).
2. Expand the branch Network adapters.
3. Find a device with names like Wireless, Wi-Fi, 802.11 or Qualcomm Atheros/Realtek/Intel.

If there is an exclamation mark next to the adapter ⚠️ — the driver is not working properly. Solutions:

For laptops DNS with chips Realtek RTL8723DE/RTL8188EE (often found in budget models) it is recommended to install drivers only from the official website, as universal versions from Windows Update may not work reliably.

4. Hardware testing: buttons and indicators

Many laptops DNS (especially models DEXP And Irbis) are equipped with physical Wi-Fi switches or keyboard shortcuts to save battery life. Check:

• 🔘 Hardware switch: There may be a slider or button with an antenna on the side of the laptop 📶.
• ⌨️ Hotkeys: usually it is Fn + F2, Fn + F12 or the key with the airplane icon (✈️ — airplane mode). On models DNS Tornado can be used Fn + Ins.
• 🔦 Wi-Fi indicator: the blue or white LED on the case should light up (if it blinks orange, the adapter is in search mode).

If the indicator does not light at all, this may mean:

• The adapter is disabled in BIOS.
• There is no power supply to the module (problem with the motherboard).
• The Wi-Fi module is physically damaged or disconnected.

5. Solving common connection errors

Even if the adapter is enabled and networks are visible, the connection may not work. Let's look at the most common errors and their solutions:

ipconfig /release
ipconfig /renew

If a laptop DNS Doesn't connect to the 5 GHz network, but sees 2.4 GHz - check the adapter's supported standards. Budget models (for example, DEXP Helios) are often equipped with modules Wi-Fi 4 (802.11n)that don't work with 5 GHz or Wi-Fi 6.

6. Alternative ways to connect to the Internet

If Wi-Fi is on the laptop DNS still doesn't work, consider temporary solutions:

• 📱 USB modem: connect your smartphone via USB and activate Modem mode (on Android or iPhone).
• 🖥️ Ethernet adapter: buy an adapter USB → RJ-45 (costs ~300₽) and connect to the router via cable.
• 🔄 Powerline adapter: If the router is far away, use adapters that transmit the Internet through electrical wiring.

For models DNS without built-in Wi-Fi (for example, some Irbis NB) you can buy an external USB adapter (we recommend TP-Link TL-WN725N or ASUS USB-AC51). They plug into any USB port and do not require complex setup.

7. When to contact the service center

If none of these methods help, the problem may be hardware-related. Contact a service center if:

• ⚡ The Wi-Fi module is not detected in the BIOS or Device Manager.
• 🔥 The laptop overheats and turns off the adapter (check the temperature through HWMonitor).
• 🛠️ There is visible damage on the case (for example, after a fall).

Cost of Wi-Fi repair on laptops DNS usually does not exceed 1500–2500₽ (module replacement). In service centers DNS There is a guarantee on the work - check this before your visit.

⚠️ Attention: On laptops DNS With Linux (for example, pre-installed Ubuntu or Astra Linux) Wi-Fi settings may differ. Use the command nmcli dev wifi list to view networks or a utility wpa_supplicant for manual connection.
