How to Check if Your Computer Has Built-in Wi-Fi: A Complete Guide

Have you bought a new computer or laptop but aren't sure if it supports wireless networks? Or has your Wi-Fi suddenly stopped working and you want to make sure the problem isn't due to a missing adapter? In this article, we'll cover the following: all possible verification methods — from standard Windows tools to diagnostics via BIOS and physical inspection of the device.

It is important to understand that even if there is a sticker with a logo on the laptop case Wi-Fi 6 or Intel AX200, this doesn't guarantee the adapter's functionality. It could be disabled in the settings, damaged, or simply missing from a specific device model. We'll show you how. distinguish between a hardware module failure and software failures - this will save you time on diagnostics.

1. Checking through Device Manager (the fastest way)

Device Manager is the main Windows tool for managing hardware. It displays all installed adapters, including network ones. To open it:

1. Press the key combination Win + X and select device Manager.
2. Expand the section Network adapters.
3. Look for devices with names Wireless, Wi-Fi, 802.11 or chip models (Intel AX210, Qualcomm Atheros, Broadcom and others).

If there is at least one such device in the list, the adapter is present. If the section Network adapters empty or contains only Ethernet controllers, this could mean:

• 🔌 The adapter is disabled in the BIOS or through a button on the laptop case.
• 🔧 The driver is not installed (there will be an item with an exclamation mark in the list).
• 🚫 There is no adapter physically (in budget PCs or older models).

2. Command line: checking network interfaces

For those who prefer console commands, there is a utility netshIt shows all network interfaces, including wireless ones. Run:

netsh wlan show interfaces

If there is an adapter, you will see a block with information about it. radio condition, SSID (network name) and supported standards (802.11n/ac/ax). If the command returns an error "No wireless interfaces" - this means one of three things:

• 📡 The adapter is disabled by software or hardware.
• 🔌 The driver is not installed or is damaged.
• ❌ The adapter is not in the system.

For more detailed diagnostics, use the command:

ipconfig /all

Look for the section in the results Wireless network adapter (Wireless LAN adapter). If it is not there, proceed to the next verification methods.

3. Checking via BIOS/UEFI (for advanced users)

In some cases, the Wi-Fi adapter may be disabled at the BIOS levelThis applies to laptops with hardware switches or corporate PCs. To check:

1. Restart your computer and enter the BIOS (usually the key F2, Del or Esc when loading).
2. Find the section Advanced, Onboard Devices or Wireless.
3. Look for parameters like Wi-Fi, WLAN, Wireless LAN - they must be able to Enabled.

If the parameter is missing altogether, this may mean the adapter isn't soldered to the motherboard (this applies to desktop PCs). In laptops, the Wi-Fi module is usually connected via a connector. M.2 (Key E) or mPCIe.

What to do if there is no Wi-Fi option in BIOS?

This is normal for desktop PCs, where the Wi-Fi adapter is often installed separately on an expansion card (e.g., PCIe). In laptops, the absence of this option may indicate a faulty module or its physical absence (in some budget models).

⚠️ Attention: BIOS settings may vary depending on the motherboard manufacturer (ASUS, Gigabyte, MSI etc.). If you are unsure of what you are doing, do not change other parameters—this may cause the system to fail to boot.

4. Physical inspection: disassembling the laptop or PC

If software methods do not produce results, there remains visual inspectionIn laptops, the Wi-Fi module is usually located under the bottom cover, near the RAM or battery. Look for a small board with antenna wires (black and white cables).

In desktop PCs, the adapter may be:

• 🖥️ Built into the motherboard (rare, usually in mini-PCs).
• 🔌 Connected via PCIe x1 or M.2 (Key E).
• 🔄 External USB adapter (looks like a flash drive).

Typical models of built-in adapters:

⚠️ Attention: Disassembling your laptop may void your warranty. If you're unsure of your skills, contact a service center. For desktop PCs, please inspect the laptop before proceeding. Be sure to turn off the power and discharge static electricity (touch the power supply housing).

5. Checking via "System Information" (msinfo32)

Utility msinfo32 Collects detailed information about your equipment. To access it:

1. Click Win + R, enter msinfo32 and press Enter.
2. Go to the section Components → Network → Adapter.
3. Search for posts with description, containing Wireless or Wi-Fi.

Here you will see not only the name of the adapter, but also its state (Included/Disabled), MAC address and the driver version. If the section is empty, the adapter is missing or not recognized by the system.

Check the physical connection of the antennas (for PC)

Update your motherboard BIOS

Install drivers from the manufacturer's official website

Try an external USB adapter for diagnostics-->

6. Diagnostics via PowerShell (alternative to the command line)

PowerShell offers more flexible tools for checking hardware. Run it as administrator and execute:

Get-NetAdapter | Where-Object {$_.Name -like "Wireless"} | Select-Object Name, InterfaceDescription, Status

This command will output:

• 📛 Adapter name (For example, Wi-Fi or Wireless network).
• 🔧 Description (chip model).
• 🔄 Status (Up - works, Down — disabled).

If the command returns no results, try the extended version:

Get-CimInstance -ClassName Win32_NetworkAdapter | Where-Object {$_.Name -like "wireless"} | Select-Object Name, DeviceID, NetConnectionStatus

7. Testing on another device (for external adapters)

If you use external USB Wi-Fi adapter (For example, TP-Link TL-WN725N or ASUS USB-AC56), you can test it on another PC or laptop. Connect the adapter to a known working system and:

1. Check if a new device has appeared in Device Manager.
2. Run a network search - if the adapter is working properly, you will see a list of available access points.

If the adapter is not detected on any device, this may indicate:

• 🔌 Mechanical damage (cable or contact breakage).
• 🔥 Chip overheating (typical for cheap models).
• ⚡ Problems with the USB port (try another connector).

FAQ: Frequently asked questions about checking your Wi-Fi adapter

My laptop is new, but the Wi-Fi isn't working. What's wrong?

Possible reasons:

1. The adapter is disabled button on the body (look for the antenna icon or Airplane Mode).
2. No drivers — download them from the laptop manufacturer’s website (not from Windows Update!).
3. BIOS reset - check the settings as in Section 3.

If the adapter is not detected at all, it might be Wi-Fi-free modification models (these are sometimes sold cheaper).

How do I find out which Wi-Fi adapter is installed in my PC?

The most reliable methods:

• Look in Device Manager (chapter Network adapters).
• Use the command wmic nic where "NetEnabled='true'" get Name, Manufacturer, Description V CMD.
• Disassemble the PC and look at the markings on the chip (for example, Intel AX200NGW).

For laptops, you can find specifications by model on the manufacturer's website (for example, support.hp.com or pcsupport.lenovo.com).

Is it possible to add Wi-Fi to a computer if it doesn't have one?

Yes, there are several options:

• 🖥️ PCIe adapter (for desktop PCs, for example, TP-Link Archer TX3000E).
• 🔌 USB adapter (universal, suitable for laptops and PCs).
• 🔄 M.2 module (for laptops with a free slot Key E).

Before purchasing, check compatibility with your system (for example, not all PCIe adapters work with older motherboards).

Why doesn't Windows detect my Wi-Fi adapter after updating?

This is a typical problem when upgrading to a new version of Windows (for example, from Windows 10 on 11). Solutions:

1. Remove the adapter in Device Manager and press Update configuration.
2. Download the driver from the manufacturer's website laptop (not a chip!).
3. Roll back to the previous driver version (Right-click → Properties → Roll Back).

If the adapter is still not detected, check it in Linux Live USB - this will help to exclude hardware failure.

How to test a Wi-Fi adapter on a Mac?

On computers Apple use:

1. Click on the icon Wi-Fi in the menu bar while holding Option (⌥) — information about the adapter will appear.
2. Open About This Mac → System Report → Network.
3. IN Terminal run the command networksetup -listallhardwareports.

In the new ones MacBook (2018+) Wi-Fi and Bluetooth are usually integrated into one chip (Apple T2).
