Where to find the MAC address on a laptop: 5 ways to connect to Wi-Fi

When your internet provider or network administrator requires you to connect your laptop to Wi-Fi MAC address, many users face the problem of where to find it. This unique network adapter identifier is like a passport for your device on the local network. Without it, the router may simply refuse traffic, even if the Wi-Fi password is entered correctly.

In this article we will look at how to quickly find out MAC address on laptops with Windows 10/11, macOS And Linux — without installing any additional programs. We'll also explain why sometimes you have to register two addresses at once (for Wi-Fi And Ethernet), and what to do if the MAC address is not displayed in the settings.

Spoiler: 90% of the time, three mouse clicks or one command in the terminal are enough. But there are some nuances that few people know about—for example, how The MAC address may be reset after updating drivers or reinstalling Windows.We'll tell you about that too.

What is a MAC address and why is it needed for Wi-Fi?

MAC address (Media Access Control) is a unique 12-digit code assigned to each network device during manufacturing. It appears as six pairs of characters separated by colons or hyphens, for example: 00:1A:2B:3C:4D:5E.

Why do they ask for it when connecting to Wi-Fi?

• 🔒 Device filteringA network administrator (for example, in an office or dorm) can allow internet access only to devices whose MAC addresses are whitelisted on the router.
• 📡 Tariff bindingSome providers (especially those on student campuses or hotels) grant access by MAC address rather than by login/password.
• 🛡️ Protection from freeloadersIf MAC filtering is enabled on your network, strangers won't be able to connect, even if they know your Wi-Fi password.

It is important to understand that the MAC address is tied to physical network adapter, not to the operating system. Therefore, if you change Wi-Fi module On a laptop, the address will also change. But if you reinstall Windows or change the user, it won't.

⚠️ Warning: MAC addresses can be spoofed (this is called spoofing), but in most home networks, this feature is disabled in the router settings. If you're offered to "hack" MAC filtering, it's a violation of the network's terms of use.

Method 1: How to find the MAC address on Windows 10 and 11

In modern versions of Windows, there are several ways to find your MAC address. The easiest is through the graphical interface:

1. Click Win + R, enter ncpa.cpl and press EnterThe Network Connections window will open.
2. Find an active connection (usually it is Wireless network for Wi-Fi or Ethernet for the cable). Right-click on it and select State.
3. In the new window, click Intelligence.... In the line Physical address The MAC address will be indicated.

If you have Windows 11, the path is a little different:

• 🖱️ Open Settings → Network and Internet → Wi-Fi (or Ethernet).
• 📋 Click on the name of your network, then scroll down to the “Properties” block - there will be a line Physical address (MAC).

An alternative method is through Command line:

ipconfig /all

Find the section in the results Wireless LAN adapter (for Wi-Fi) or Ethernet adapter (for cable). The MAC address will be listed in the line Physical address.

⚠️ Attention: If there are several adapters with the same name in the list (for example, Wi-Fi 2 And Wi-Fi 3), focus on status ConnectedInactive adapters may be related to virtual networks or outdated drivers.

Make sure the adapter is turned on (no cross on the Wi-Fi icon) | Copy the address without spaces or dashes | Check that this is a Wi-Fi address, not an Ethernet one (if you are connecting over the air) | Compare the first 6 characters with the manufacturer's table (see section below) -->

Method 2: MAC address on laptops with macOS (Apple)

On MacBook or iMac With macOS Finding a MAC address is even easier:

1. Click on the icon Wi-Fi in the upper right corner of the screen (next to the clock).
2. Select an item Wi-Fi settings (or Open network settings in older versions).
3. At the bottom of the window, click Additionally..., then go to the tab Equipment. The MAC address will be indicated in the line Ethernet ID (yes, even for Wi-Fi!).

For macOS Ventura and newer:

• 🍎 Open System Preferences → Network → Wi-Fi → More....
• 🔍 The MAC address will be displayed in the section Interface under the name Ethernet address.

You can also use Terminal:

networksetup -listallhardwareports

Find the section in the results Wi-Fi or AirPort (on older Macs) - the MAC address will be in the line Ethernet Address.

Method 3: Finding the MAC address on Linux (Ubuntu, Mint, Fedora)

In distributions Linux You can find the MAC address through the terminal or the graphical interface (if installed). The universal method for all versions:

ip link

Look for a line with the name of your Wi-Fi adapter (usually wlan0, wlp3s0 or similar). The MAC address will be indicated after the word link/ether.

For Ubuntu with interface GNOME:

• 🐧 Click on the network icon in the upper right corner → Network settings.
• 📡 Select your Wi-Fi connection and click the gear icon ("Settings").
• 🔧 The MAC address will be in the section Device under the name Hardware address.

If you have KDE Plasma (for example, in Kubuntu):

1. Open System Settings → Network.
2. Select an active connection → Equipment.
3. The MAC address will be in the line MAC address (original, right?).

⚠️ Note: In some distributions (for example, Arch Linux) network interface names may change after updates. If the command ip link shows an unknown adapter (for example, wlx00c0caabcdef), check its status with the command iwconfig - the active adapter will be marked as IEEE 802.11.

How to determine which MAC address is needed: Wi-Fi or Ethernet

A common mistake users make is sending the MAC address to the network administrator. Ethernet-port when an address is required Wi-Fi, and vice versa. How to avoid confusion?

If you are not sure what address you need:

• 📶 Are you connecting via Wi-Fi? Look for the MAC address of the wireless adapter.
• 🔌 Connected via cable? Need an address Ethernet-port.
• ❓ Don't know your connection type? Check which icon is active in the tray (antenna or RJ-45 connector).

Wi-Fi only|Cable only|Both, depending on the situation|USB modem/4G-->

What to do if the MAC address is not displayed

Sometimes in the network settings the MAC address may be missing or displayed as 00-00-00-00-00-00Causes and solutions:

• 🔌 The adapter is disabled. Turn on Wi-Fi using the button on your laptop (sometimes it is Fn + F2 or a separate switch).
• 🔄 The driver is not installed. Open device Manager (Win + X → Device Manager) and check if there is an exclamation mark next to Network adapters.
• 🛠️ Virtual adapterSome VPNs (for example, Hamachi) create virtual network cards. Ignore them—you need a physical adapter.
• 🔍 Hidden adapter. IN Device Manager enable display of hidden devices (View → Show hidden devices).

If the problem is in the drivers:

1. Download the driver for your laptop model from the manufacturer's website (Dell, HP, Lenovo etc.).
2. Uninstall the current driver in Device Manager (right click → Remove device).
3. Install the downloaded driver and restart your laptop.

How to check if a Wi-Fi adapter works without drivers?

Even without drivers, the adapter may be displayed in Device Manager as "Unidentified Device" or "Network Controller." If it's not there at all, the adapter may be disabled in the BIOS/UEFI. To access it, press [Enter] when booting the laptop. F2, Del or Esc (depending on the model). Look for the section Advanced → Onboard Devices Configuration and make sure that Wireless LAN included (Enabled).

Is it possible to change the MAC address and why would you want to do so?

Yes, the MAC address can be changed programmatically - this is called MAC spoofingBut do you need it?

Legitimate reasons for changing your MAC address:

• 🔄 Bypassing restrictionsSome public networks (such as those at airports) block devices after a certain amount of use. Changing the MAC address allows you to reset the limit.
• 🛡️ Privacy. The MAC address can be used to track your device in public places (for example, through Wi-Fi scanners in shopping centers).
• 🔧 Network testingAdministrators sometimes change MAC addresses to simulate different devices when configuring a router.

How to change MAC address in Windows:

1. Open device Manager → Network adapters.
2. Right-click on your Wi-Fi adapter → Properties → Advanced.
3. In the list of properties, find Network Address or Network address.
4. Enter a new MAC address without colons (For example, 001A2B3C4D5E) and reboot.

On macOS And Linux This requires a terminal and administrator rights. For example, on Linux:

sudo ifconfig wlan0 down
sudo ifconfig wlan0 hw ether 00:11:22:33:44:55
sudo ifconfig wlan0 up

⚠️ Warning: Changing the MAC address may disrupt the operation of some corporate networks (e.g. 802.1X authentication). Also, some providers link tariffs to the original MAC address; after changing it, the internet may disappear.

FAQ: Frequently Asked Questions About MAC Addresses on Laptops

Can a MAC address change on its own?

Yes, in rare cases:

• After replacement Wi-Fi module or network card.
• When resetting BIOS/UEFI on some laptops (for example, Lenovo with function MAC Address Pass-Through).
• If a virtual machine is used, its MAC address is generated randomly each time it is started.

In other cases, the MAC address remains constant.

Why do I have two MAC addresses for Wi-Fi?

Modern laptops are often equipped with two Wi-Fi modules:

• Basic (For example, Intel AX200) - for normal connection.
• Auxiliary (For example, Bluetooth adapter with Wi-Fi Direct support).

To connect to the router you need an address main adapter (usually it is the first one on the list).

Is it possible to connect to Wi-Fi without a MAC address?

Technically yes, if:

• On the router MAC filtering is disabled (most home networks).
• You are connecting via WPS (button on the router) - in this case, the MAC is not checked.
• Are you using guest network, where filtering is not configured.

But if the network administrator explicitly requires a MAC address, it will not be possible to bypass this rule without his consent.

How can I find out a laptop's MAC address remotely (for example, for a relative)?

If you have access to the laptop through TeamViewer, AnyDesk or RDP, follow the same steps as described above. Alternative methods:

• Ask them to send you a screenshot of the window. ipconfig /all (for Windows).
• If on a laptop macOS, let them copy the command output networksetup -getmacaddress Wi-Fi.
• For Linux the team will do cat /sys/class/net/wlan0/address.

Important: Make sure the user sends the address active adapter, not a virtual one (for example, VMware or VirtualBox).

What do the first 6 characters of a MAC address mean?

The first three bytes (6 characters) of a MAC address are called OUI (Organizationally Unique Identifier) and indicate the manufacturer of the network adapter. For example:

• 3C:22:FB — Apple (MacBook, iPhone).
• 78:31:C1 — AzureWave (used in some models) HP And Dell).
• 00:1A:79 — Intel (popular Wi-Fi modules in laptops).
• 00:0C:29 — VMware (virtual network cards).

A full list of OUIs can be found on the website IEEEThis helps to distinguish between a physical adapter and a virtual one.
