Every device capable of connecting to a wireless network has a unique physical identifier assigned by the manufacturer at the factory. This code, known as MAC address, serves as a digital identification number for the equipment in the local network and allows the router to accurately identify who is requesting internet access. Without this hexadecimal value, proper data routing and the functioning of home network security systems are impossible.
Knowing how to find this ID is necessary not only for setting up filtering by MAC addresses On the router, but also for diagnosing connection issues when the network administrator blocks access to unknown devices. In modern operating systems, the path to this information may be hidden deep in menus, but there are several proven ways to quickly obtain the necessary data. We'll cover methods for all popular platforms, including mobile OS and desktop computers.
Understanding the structure of this address will help you distinguish a real device from a virtual adapter, which is especially important for laptops that support multiple frequency bands. Users often get confused when seeing several similar entries in the list, but a clear understanding of the search algorithm will prevent errors. Below, we'll cover the steps for various use cases in detail.
What is a MAC address and why is it needed in Wi-Fi networks?
Media Access Control — is a physical address hardwired into a device's network card or Wi-Fi module during manufacturing. It consists of 12 hexadecimal digits separated by colons or hyphens and is theoretically unique for every device in the world. Unlike an IP address, which can change with each connection or router reboot, MAC address remains constant (except when using special randomization functions in newer operating systems).
In the context of wireless networks, this identifier plays a critical role in access control. Administrators use it to create "whitelists," allowing only trusted devices to connect, or "blacklists," blocking access to uninvited guests. This code can also be used to pinpoint the exact device consuming traffic if the network experiences abnormal load.
⚠️ Note: In modern versions of iOS, Android 10+, and Windows 10/11, MAC address randomization is enabled by default to enhance privacy. This means the device can generate a random address when scanning networks, hiding its real physical identifier.
For a typical home network where you configure the router yourself, it's important to distinguish between the real and random IP addresses, especially if you use filtering. If you enter the real IP address into the router settings, but the phone broadcasts a random IP address, the connection will fail. Therefore, when setting up security, always check which IP address is currently being broadcast.
How to find the MAC address on a Windows computer
There are several ways to access network adapter information in the Windows operating system, from the graphical interface to the command line. The fastest and most reliable method, which works on all OS versions, from Windows 7 to Windows 11, is using the console. This method eliminates the risk of error, as you see the raw data directly from the driver.
To do this, you need to launch the command line. Press the key combination Win + R, enter cmd and press Enter. In the window that opens, enter the command ipconfig /allThe system will display a detailed list of all network interfaces. Find the section corresponding to your wireless adapter (usually labeled "Wireless" or containing the word "Wireless").
C:\Users\User> ipconfig /allIn the list of parameters, find the line Physical address (Physical Address). The value next to this line (e.g., 00-1A-2B-3C-4D-5E) is the MAC address of your Wi-Fi module. Please note that the list may contain multiple adapters, including virtual ones (e.g., from VMware or VirtualBox) and Bluetooth, so it's important to select the Wi-Fi one.
☑️ Data verification in Windows
An alternative method is through the settings graphical interface. Go to Settings → Network and Internet → Wi-FiClick on . Equipment properties Or select an active connection and look for the "Physical Address (MAC)" field. This method is more intuitive for beginners, but may display a randomized address if the privacy feature is enabled.
Finding MAC Addresses on Android and iPhone Smartphones
Mobile device owners often need to know the MAC address to connect to corporate networks or hotel Wi-Fi with authorization. On smartphones running Android The path to this information may differ slightly depending on the system version and the manufacturer's shell (Samsung, Xiaomi, Huawei).
The standard algorithm for most Android devices is as follows: open Settings, go to the section About the phone (or "System"), then select Status or StateThis menu will have an item called "Wi-Fi MAC Address." On some Samsung models, the path may be different: Settings → Connections → Wi-Fi → Click the gear icon for your current network → View MAC address.
- 📱 On Xiaomi (MIUI): Settings → About phone → All specs → Wi-Fi status.
- 📱 On Huawei/Honor: Settings → System → About phone → Status.
- 📱 On a stock Android device: Settings → About phone → Details → MAC address.
For users iPhone (iOS) The procedure is even simpler, but has its own nuances related to Apple's privacy policy. Go to Settings → General → AboutFind the line Wi-Fi addressImportant: iOS 14 and later use a "Private Wi-Fi Address" for each network separately. If you're setting up filtering on your router, you may need to disable this feature for that specific network or use the primary address from the "About" section.
What is "Private Address" on iPhone?
This is a security feature that generates a unique MAC address for each Wi-Fi network you connect to. This prevents access point owners from tracking your location, but it can cause issues with router filtering.
Instructions for macOS and Linux systems
Users of Apple Mac computers and Linux operating systems can also easily access the physical address of a network interface. In macOS, this is done through the highly visual System Preferences. Open the Apple menu (the apple in the upper left corner) and select System Preferences (or System Preferences in older versions).
Go to the section NetSelect your active Wi-Fi connection from the list on the left and click the button Additionally... (Advanced). In the window that opens, go to the tab Hardware (Hardware). The first line will contain the MAC address you're looking for. You can also see the MTU and other technical connection parameters here.
In the operating system Linux (Ubuntu, Mint, Fedora, etc.) The most universal method is to use the terminal. Open the terminal and enter the command ip link or ifconfig (if the net-tools package is installed). In the command output, find the interface, usually called wlan0 or wlp2s0. The parameter will be indicated next to the interface name. link/ether, followed by the address.
ip link show wlan0The graphical interface in Linux (GNOME, KDE) also allows you to view this information. In Ubuntu, for example, you need to click the network icon in the upper right corner, select Wi-Fi settings, click on the gear next to the connected network and go to the tab IdentifierThe wireless network address will be listed there.
How to find the MAC address on a router
Users often need to know the MAC address of the router itself (WAN MAC) rather than the client device, especially when connecting to a provider that uses hardware tethering. The easiest way is to look at the sticker on the bottom of the device. It usually lists two addresses: one for LAN/WLAN and one for WAN (Internet).
If the sticker is worn off or unavailable, you can find the information in the administrator's web interface. Access the router settings in a browser (usually at 192.168.0.1 or 192.168.1.1). The section has different names depending on the brand: Status, Network, System Information or WAN SettingsThere will be a field there. MAC Address or Physical Address.
| Router brand | A typical menu section | Where to find MAC |
|---|---|---|
| TP-Link | Status | Network / WAN |
| ASUS | Network environment | Internet (WAN) |
| Keenetic | Internet (Basic) | Connection parameters |
| D-Link | Advanced settings | WAN / Network |
Some ISPs require MAC address cloning. This means that the router must present itself to the ISP as the same address your computer previously used. Clone MAC Address It is usually located in the same WAN settings and allows you to copy the address from a connected PC with one click.
Setting up filtering and address cloning
Once you've found the MAC addresses of your devices, you can begin setting up security. Filtering allows you to create strict access rules. In the router settings (section Wireless → Wireless MAC Filtering) you can select the mode: "Allow only listed" (white list) or "Deny listed" (black list).
When adding a device to the whitelist, make sure you enter the address correctly. Use only numbers 0-9 and the letters AF. Separators (colons or hyphens) may be optional in some interfaces, or may be required—be careful with the input mask. Once the settings are applied, all devices not on the list will immediately lose Wi-Fi access.
⚠️ Note: Router interfaces and operating systems are frequently updated. The layout of menu items may change in new firmware versions. If you don't find the option you're looking for, search for similar names or refer to your router manufacturer's official documentation.
The MAC address cloning feature is useful when your ISP has blocked access after replacing your equipment. Instead of calling tech support, you can "trick" your ISP's system by forcing your router to broadcast the address of an old, trusted device. This is done in the WAN settings section, where there's a button. Clone MAC Address or a field for manual input.
Frequently Asked Questions (FAQ)
Is it possible to change the MAC address permanently on a phone?
On most modern smartphones, changing the hardware MAC address is impossible, as it's hardcoded into the chip. However, this can often be done through software (at the driver level), but a factory reset or system reinstallation will reset the address to the factory default. On Android, this requires root access, and on iOS, jailbreaking, which is not recommended for regular users.
Why is my MAC address different from the one on the sticker?
This happens because of the randomization feature (Private Wi-Fi Address), built into modern operating systems for security. The device creates a temporary, random address for connecting to a specific network. To see the actual factory address, you need to disable this feature in the Wi-Fi settings for the specific network or look in the "About phone/About device" section.
Is MAC address dangerous for my security?
The MAC address itself doesn't pose a critical threat, but it can be used to track your movements between access points (geolocation). This is why Apple and Google implemented randomization. Knowing your MAC address, a hacker won't be able to steal data from your device directly, but they can try to impersonate your device to access the network if you don't have a password.
How many characters are in a MAC address?
A standard MAC address (MAC-48) consists of 48 bits, which in hexadecimal notation equals 12 characters (the numbers 0-9 and the letters AF). These are typically broken into six pairs and separated by colons or hyphens (e.g., 00:1A:2B:3C:4D:5E).
