How to find out if your computer has a Wi-Fi adapter: step-by-step instructions with photos

You've bought a new (or used) computer and want to connect to a wireless network, but you're not sure if it has one. Wi-Fi adapterOr has your Wi-Fi suddenly stopped working, and you're wondering if the problem is in the drivers or the hardware? We'll figure it out in this article. all possible verification methods, from simple to advanced, including diagnostics through BIOS, device Manager and even a physical inspection of the motherboard.

It's important to understand that having an adapter is only half the battle. It can be disabled in settings, lack drivers, or simply burn out. Therefore, we will not only show you how to find the Wi-Fi module, but also provide a checklist for quickly diagnosing its functionality. If you are a user Windows 10/11, Linux or even MacOS — the instructions are suitable for all systems (taking into account the specific features).

Spoiler: in 90% of cases, the problem is solved in 5 minutes - just update the driver or turn on the adapter in BIOS. But if you are faced with hardware failure (for example, burnt contacts on the M.2 module), we will tell you how to determine this without disassembling the PC.

1. Checking through the Device Manager (the fastest way)

This is a basic method that works on all versions. Windows — from XP to Windows 11It will show whether the system recognizes the Wi-Fi adapter, even if it is disabled or not working.

Open device Manager in one of the following ways:

• 🔹 Click Win + R, enter devmgmt.msc and press Enter.
• 🔹 Right-click on Start → Device Manager.
• 🔹 In Windows 11: Settings → System → Device Manager.

In the window that opens, find the section Network AdaptersOpen it and look for lines with the words:

• 📶 Wireless (For example, Intel Wireless-AC 9560)
• 📶 Wi-Fi or WiFi (For example, Qualcomm Atheros QCA61x4A)
• 📶 802.11 (wireless network standard, for example, Realtek 802.11ac)

Check the "Other devices" section for unknown devices|Update your hardware configuration (the "Update" button at the top of the window)|Restart your PC and check again|Try the command line method (section 3)

-->

If there is an adapter, but there is a light next to it yellow exclamation mark — the problem is in the drivers. If it is not there at all, it may be disabled in BIOS or is physically absent.

⚠️ Attention: In laptops, the adapter can be built into the motherboard or connected as a separate module. M.2 (For example, Intel CNVi). In desktop PCs it is most often installed on PCIe board or integrated into the motherboard (budget models may not have it at all).

2. Checking via Windows Settings (for Windows 10/11 users)

This method is simpler than the previous one and doesn't require digging into system utilities. It's suitable if you need to quickly find out if your PC can connect to Wi-Fi. right now (and not just check for the presence of hardware).

Open Parameters (Win + I) and go to the section:

• 🖥️ Windows 10: Network and Internet → Status
• 🖥️ Windows 11: Network and Internet → Wi-Fi

If you see a button in the list of available networks «Wi-Fi» (even if it is turned off), then the adapter is present and working. If the section Wi-Fi none at all - there is either no adapter or it is disabled.

Please note the connection status:

• 🔴 "No connections available" — there is an adapter, but it doesn’t see the network (problem with drivers or antennas).
• 🟡 "Wi-Fi is disabled" — the adapter is present, but it is turned off by software (press the power button).
• 🟢 List of networks — everything works, you can connect.

3. Diagnostics via the command line (for advanced users)

If you need detailed information about the adapter - its model, supported standards (802.11n/ac/ax), MAC address, and status—use the command line. This method is universal and works even if the GUI Windows does not answer.

Open Command line as administrator (Win + X → Terminal (Administrator)) and enter:

netsh wlan show drivers

In the results, look for the following lines:

• 📋 "Name" — adapter model (for example, Realtek RTL8822CE).
• 📋 Radio Type - if specified 802.11, the adapter supports Wi-Fi.
• 📋 Hosted Network Support — Yes means that the PC can distribute Wi-Fi.

If the command returns an error The operation could not be completed., the adapter is not present in the system or is disabled. For further verification, enter:

ipconfig /all

Look for the section in the results Wireless Network AdapterIf it is not there, the adapter is missing or not recognized by the system.

wmic nic where"NetEnabled='true'" get Name, NetConnectionID

4. Checking via BIOS/UEFI (if the adapter is disabled at the hardware level)

Sometimes the Wi-Fi adapter physically present in the system, but disabled in the settings BIOSThis is relevant for laptops where manufacturers (for example, Lenovo, HP, Dell) add an option to disable wireless modules to save energy.

To check:

1. 🔧 Restart your PC and go to BIOS (usually a key F2, Del, Esc or F12 at startup).
2. 🔧 Find the section Advanced, Configuration or Wireless.
3. 🔧 Look for options like:
   • 📡 Wireless LAN (should be Enabled)
   • 📡 Wi-Fi or WLAN
   • 📡 Onboard Wi-Fi (on motherboards ASUS, Gigabyte)

⚠️ Attention: In some laptops (especially Dell Latitude or HP EliteBook) Wi-Fi may be blocked hardware switch on the body or by a combination of keys (for example, Fn + F2). Check them before changing the settings. BIOS!

5. Physical inspection (computer disassembly)

If all software methods have failed, there remains visual inspectionThis is relevant for desktop PCs and some laptops, where the adapter can be connected as a separate module.

Where to look:

Examples of popular modules:

• 🔌 Intel AX200/AX210 (supports Wi-Fi 6)
• 🔌 Qualcomm Atheros QCA6174 (often found in laptops Lenovo)
• 🔌 Realtek RTL8822CE (budget option for PC)
• 🔌 Broadcom BCM4352 (found in MacBook and some ASUS)

⚠️ Attention: In older or budget motherboards (eg. Gigabyte H310 or ASRock B450M-HDV) There may not be a Wi-Fi adapter at all. Check the specifications for your model on the manufacturer's official website.

6. Testing on Linux and macOS

If you use Linux (For example, Ubuntu, Mint) or macOS, the verification methods will be different. Here are brief instructions:

For Linux:

1. 🐧 Open the terminal (Ctrl + Alt + T).
2. 🐧 Enter the command:

   lspci | grep -i network

   Or for USB adapters:

   lsusb

3. 🐧 Look for lines with Wireless, Wi-Fi or chip names (Atheros, Broadcom).

For macOS:

1. 🍎 Click Option (Alt) and click on the icon Wi-Fi in the menu bar.
2. 🍎 Open About This Mac → System Report → Network.
3. 🍎 In the section Wi-Fi the adapter model will be indicated (for example, AirPort Extreme or Broadcom BCM43xx).

IN Linux you can also use the command iwconfig, which will show all wireless interfaces. If the output is empty, the adapter is missing or not recognized by the kernel.

7. What to do if there is no adapter?

If after all the checks it turns out that there is no Wi-Fi adapter on your computer, you have several options:

• 🔄 Buy an external USB adapter (For example, TP-Link TL-WN823N or ASUS USB-AC56). Suitable for temporary use.
• 🔄 Install the internal module:
  • 🖥️ For PC: PCIe adapter (For example, TP-Link Archer T6E).
  • 💻 For laptop: M.2 module (For example, Intel AX200).
• 🔄 Use a Powerline adapter (Internet transmission via electrical wiring) or Ethernet (if the router is nearby).
• 🔄 Update your motherboard (if your model does not support Wi-Fi, but you need a built-in module).

When choosing an adapter, pay attention to:

• 📡 Wi-Fi standard: 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6).
• 📡 Frequencies: 2.4 GHz (range) + 5 GHz (speed).
• 📡 Bluetooth support (if you need both Wi-Fi and Bluetooth in one module).
