How to find your computer's WiFi MAC address: detailed instructions

Every network device in the world has a unique identifier assigned by the manufacturer at the factory. This code, known as MAC address, used to accurately identify your equipment on the local network and when connecting to the internet. Users often need to find this number when their ISP restricts access by hardware ID or when they need to configure client filtering on their router.

There are several reliable methods for detecting this code, and the specific method you choose depends on your operating system and your level of command line access. In this article, we'll look at how to find the adapter's physical address in Windows 10, Windows 11 And macOSWe'll also consider cases where software methods aren't available. Understanding the structure of this address will help you manage your home network with greater confidence.

It's important to distinguish between the local network (Ethernet) address and the wireless module address, as a modern laptop may have two different ones. We'll focus on the wireless interface, which is designated as Wi-Fi or Wireless LANLet's start with the most basic built-in operating system tools.

Using the Command Prompt in Windows

The fastest and most versatile way to obtain information about network interfaces is to use a system command-line utility. This method works on all versions of Windows starting with XP and doesn't require a graphical interface, making it ideal for remote administration or working on older PCs.

First, you need to launch the console. Press the key combination Win + R, enter cmd and press Enter. In the black window that opens, enter the command ipconfig /all and wait for a list of all network adapters to appear. You need to find the section corresponding to your wireless connection, which is usually labeled "Wireless Network" or contains the word Wireless.

In the adapter's detailed description, look for the "Physical Address" line. The value next to it is the identifier you're looking for. It's a sequence of 12 hexadecimal digits separated by hyphens or colons. If you see multiple adapters, make sure you're looking specifically at the Wi-Fi module's data, not the virtual machine or Bluetooth data.

⚠️ Note: Windows 10 and 11 have the "Randomize Hardware Addresses" feature enabled to enhance privacy. If you see an address different from the one on the device's label, the system may be using a temporary identifier. It's best to use the actual physical address for MAC filtering in your router.

An alternative way to get the same information is to use a more modern utility. getmacIt produces results in a more compact format, immediately showing the transport name and physical address. Enter the following in the command line:

getmac /v /fo list

Here is the key /v means a detailed output, and /fo list Formats the result as a list. Find the "Physical Address" line under the name of your wireless adapter. This method is especially convenient if you need to quickly copy data without unnecessary text.

Finding an address using network settings in Windows 10 and 11

If you prefer a graphical interface and don't want to mess around with code, the operating system provides convenient menus for viewing connection properties. The settings interface in Windows 10 And Windows 11 It's slightly different, but the search logic remains similar. This method is great because it immediately displays the connection status and additional details.

In Windows 10, right-click the network icon in the system tray (near the clock) and select "Open Network & Internet Settings." In the window that opens, find the "Properties" link under the name of your Wi-Fi network. Scroll down to the "Properties" section, where you'll see the line "Physical Address (MAC)."

In Windows 11, the path has changed slightly due to the new menu design. Go to "Settings" → "Network & Internet" → "Wi-Fi." Click the name of your current network (usually the first line with the "Properties" button). In the network properties window that opens, scroll to the bottom of the page—you'll find the number you need there.

• 📡 Right-click on the Wi-Fi icon in the tray.
• 🖥️ Select "Network & Internet settings".
• 🔗 Click on "Properties" of the active network.
• 👀 Find the line "Physical address".

The advantage of this method is that you see the address of the interface that's currently active. This eliminates confusion with wired adapters or virtual devices that may appear in Device Manager. You can also see the security type and IP protocol here.

Finding your MAC address on macOS

For computer owners Apple the procedure is also not difficult, although the system interface macOS has its own specifics. The wireless adapter's address can be found in the system settings, and you'll need it, for example, to connect the device to a corporate network or home router.

In modern versions of macOS (Ventura, Sonoma, and newer), open System Preferences from the Apple menu. Go to the "Wi-Fi" section in the sidebar. Click the "Advanced..." button next to the Wi-Fi switch. In the window that opens, select your network or simply look at the bottom of the window, where the MAC address is often listed.

In older versions (Monterey and earlier), the path is: "System Preferences" → "Network." Select Wi-Fi from the list on the left, then click the "Advanced" button in the lower right corner. Go to the "Hardware" tab. The MAC address will be listed in the top line.

You can also use the Terminal, which is a powerful tool on macOS. Open Terminal and enter the command:

networksetup -listallhardwareports

This command will list all network ports. Find the block labeled "Wi-Fi" and copy the value after "Ethernet Address." This is your identifier. The macOS terminal often provides more accurate information about the adapter's physical status than the graphical interface.

What is a Wi-Fi and Ethernet address in macOS?

Apple has implemented a privacy protection feature in new MacBooks that can generate a private Wi-Fi address for each network. You can see if this feature is enabled in Wi-Fi Preferences -> Advanced -> Private Wi-Fi Address. To configure your router, use the address listed in the "Hardware" section.

Viewing via Device Manager and PowerShell

For advanced users who need detailed technical information, Device Manager or PowerShell are suitable. These tools not only allow you to view the address but also manage the adapter drivers, which is useful for diagnosing connection issues.

In Device Manager, right-click "Start" and select the appropriate item. Expand the "Network adapters" branch. Find your wireless adapter (usually the name contains the words "Wireless," "Wi-Fi," or a brand name like Intel, Realtek, Qualcomm). Right-click → "Properties" → "Advanced" tab. In the list of properties, find "Network Address" or "Locally administered address." If there's a value there, the address has been overridden programmatically. If the field is empty, the default one is used.

PowerShell offers even more flexibility. Open PowerShell and enter the following command:

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

This script will filter only wireless adapters and display their names and MAC addresses. This is especially useful if the system has many virtual adapters from hypervisors or VPN clients that create noise in the overall list.

⚠️ Caution: Changing your MAC address (spoofing) through Device Manager or the registry may result in loss of network access if your ISP uses hard-coded MAC addressing. Write down the original value before making any changes to your adapter settings.

Physical markings and documentation of the device

If your computer won't turn on or the operating system won't load, you can find the address physically. On most laptops and USB adapters, the manufacturer places this code on a special sticker. This is the only way to find the address if the network card drivers aren't installed.

Look for a sticker on the bottom cover of the laptop, under the battery (if it's removable), or on the device's box. This information is often duplicated in the BIOS/UEFI. To enter the BIOS, press a special key (F2, Del, F10) when booting the computer and find the section related to System Information or Onboard Devices.

The format on the labels may differ from the software. It is often indicated as "MAC," "MAC ID," or "Physical Address." Sometimes a barcode or QR code may be displayed next to the hexadecimal code for quick scanning.

For USB Wi-Fi adapters, the sticker is usually located on the device itself or on a paper insert inside the box. If the sticker has worn off and the device is not detected by the system, the only solution is to consult the documentation or search for the adapter model online, although this is less reliable.

Checking the router's web interface

If your computer is already connected to your Wi-Fi network, the easiest way to find its address is to look at the client list in your router settings. This method is useful because it displays the address currently visible on the network, eliminating the possibility of typing errors.

Log into your router's web interface (usually at 192.168.0.1 or 192.168.1.1). Find the section labeled "Wireless Statistics," "Client List," "DHCP Client List," or "Client List." The table displays your device's hostname, IP address, and MAC address.

Below is an example table of what the list of connected devices might look like in the router interface. TP-Link or ASUS:

Once you find your device in the list, you can copy the address directly from your browser. This is especially useful if you need to whitelist an address for filtering. Note that some routers allow you to rename devices for convenience, but the MAC address remains the key.

⚠️ Note: Router interfaces from different manufacturers (Keenetic, MikroTik, D-Link) may vary significantly. The location of the client lists depends on the firmware version. If you can't find the section you need, consult the official manual for your router model, as terminology may change.

Frequently Asked Questions (FAQ)

Can a Wi-Fi MAC address change on its own?

The factory address itself cannot be changed, as it is hardcoded into the chip. However, operating systems (Windows 10/11, iOS, Android) can generate a random temporary address for each new network for privacy purposes. In Wi-Fi settings, this is called "Random Hardware Address." For permanent filtering in the router, the actual physical address must be used.

What is the difference between a MAC address and an IP address?

A MAC address is a unique physical identifier for a network card, which doesn't change (in most cases) and operates at the hardware level. An IP address is a logical address assigned to a device on the network (by a router or ISP) and can change with each reconnection. A MAC address is used for device identification, and an IP address is used for data routing.

What should I do if my MAC address in Device Manager consists of zeros?

If you see the address 00-00-00-00-00-00, this usually means the network card driver is not installed or is not working correctly. Try reinstalling the Wi-Fi adapter drivers from the official website of the laptop or motherboard manufacturer. Without the correct driver, the system cannot read data from the chip.

Is it safe to change MAC address?

The spoofing procedure itself is safe for your equipment, but it can lead to loss of network access if your provider uses IP address binding. It can also disrupt local filtering rules. Always record the original value so you can restore everything to its original state.
