How to find your router's ID: MAC address, SSID, and serial number in 5 minutes

When it comes to Wi-Fi router ID, users often confuse three key concepts: MAC address (unique physical identifier of the device), SSID (wireless network name) and serial number (factory code of the manufacturer). Each of them may be needed in different situations: from setting up device priority in the router before registering the gadget with the provider or solving connection problems.

In this article, we'll discuss how to quickly find any of these identifiers, regardless of your router model. These methods work for popular brands: TP-Link, ASUS, Keenetic, Xiaomi, Zyxel, MikroTik, as well as for routers from providers (Rostelecom, MTS, Beeline). It doesn't matter whether you need it or not. MAC address to bind to an Internet provider or SSID to connect a new device - You will find the solution here.

1. What is a router ID and why is it needed?

The term "router ID" is often used as a generic term for three different identifiers. Let's look at how they differ and where they are used:

• 🔹 MAC address - a unique 12-digit code (for example, 00:1A:2B:3C:4D:5E), which is assigned to the router's network card at the factory. It is needed for:
  • Binding the device to the provider (for example, Rostelecom or Dom.ru).
  • Settings MAC filtering in the security settings.
  • Diagnosing connection problems (your provider may request this for verification).
• 📡 SSID — the name of your Wi-Fi network, which is displayed in the list of available connections. It can consist of letters, numbers, and symbols (for example, MyHomeWiFi_5G). Required for:
  • Connecting new devices (smartphones, laptops, smart speakers).
  • Settings guest network or frequency separation (2.4/5 GHz).
• 🏷️ Serial number (S/N) — the factory code indicated on the router sticker (for example, CP123456789RU). Useful for:
  • Warranty service.
  • Checking the originality of the device (on the manufacturer’s website).
  • Recover access if you forgot your admin panel password.

If you need bind the router to the provider, most likely it will be required MAC addressTo connect a new phone to Wi-Fi - SSIDAnd to contact support - serial number.

⚠️ Please note: Some providers (eg. MGTS or Third Transport Ring) may use the term "hardware ID" instead of "MAC address." Check with your carrier to determine which identifier is required to avoid confusion.

2. Method 1: Find the ID on the router sticker

The fastest method is to look at the data on factory sticker, which is usually located:

• 📦 On the bottom side of the case (on most models) TP-Link, ASUS, D-Link).
• 🖥️ On the back panel (for vertical routers, for example) Keenetic or Zyxel).
• 📄 Inside the SIM card compartment (for 4G/5G routers, for example, Huawei B535).

On the sticker you will find:

If the sticker is worn off or missing (for example, on a used device), proceed to the following methods. Also note that MAC address on the sticker may refer to LAN port, and not to the Wi-Fi module - we will talk about this below.

3. Method 2: View the MAC address and SSID in the router settings

If you have access to router web interfaceYou can find all the necessary identifiers in the settings menu. The instructions are universal for most models, but the paths to the sections may vary slightly.

Steps to enter settings:

1. Connect to your router via cable (recommended) or Wi-Fi.
2. Open your browser and enter one of the IP addresses in the address bar:
   • 192.168.0.1 (For D-Link, TP-Link)
   • 192.168.1.1 (For ASUS, Keenetic)
   • 192.168.8.1 (For Xiaomi)
   • 10.0.0.1 (for routers from Rostelecom)

Enter your login and password (by default it is often admin/admin or indicated on the sticker).

Next we look for identifiers:

• 🔍 MAC address:
  • IN TP-Link: Advanced → Network → MAC Clone.
  • IN ASUS: Administration → System (chapter MAC Address).
  • IN Keenetic: General Settings → Device (field WAN MAC address).
  What is the difference between WAN MAC and LAN MAC?

  WAN MAC is the address used to connect to the ISP (important for binding). LAN MAC is the local network address (needed for device filtering).

• 📡 SSID:
  • IN Xiaomi: Wi-Fi → Basic Settings (field Wi-Fi Name).
  • IN Zyxel Keenetic: Wi-Fi network → Main network.

If you can't find the section you need, use the settings search (usually the magnifying glass icon in the top menu).

4. Method 3: Find out the MAC address via the command line (Windows/macOS/Linux)

If you don't have access to your router settings (for example, you forgot your password), but the device is connected to your computer, you can find out its MAC address via network utilities.

For Windows:

1. Open Command line (Win + R → enter cmd → Enter).
2. Run the command:

   arp -a

   In the list, find the IP address of your router (for example, 192.168.1.1) - his MAC will be next to him.

For macOS/Linux:

1. Open Terminal.
2. Enter:

   arp -n | grep 192.168.1.1

   (replace 192.168.1.1 to your router's IP).

This method will show MAC address of the LAN port router. To see MAC of the Wi-Fi module, connect to the router's network wirelessly and use the command:

netsh wlan show interfaces

(Windows only) In the line BSSID will be the MAC of the access point.

⚠️ Note: If your router issues an IP via DHCP, its address on the local network may change. Before executing the commands, check your current IP via ipconfig (Windows) or ifconfig (macOS/Linux).

5. Method 4: Use a mobile app

Router manufacturers often release official apps for controlling the device from a smartphone. They not only show MAC address And SSID, but also allow you to change them without logging into the web interface.

Popular apps:

• 📱 Tether (For TP-Link) - shows MAC in the section Device Info.
• 📱 ASUS Router — Device ID in Network Map → Clients.
• 📱 Mi Wi-Fi (For Xiaomi) - data in Router Settings → Status.
• 📱 Keenetic — MAC and SSID in the main menu under the router name.

Apps typically display identifiers on the home screen or in the "Device Information" section. If the app isn't connecting, check:

• Are you connected to a Wi-Fi router (not to mobile Internet).
• Is your router firmware updated (outdated versions may not support the app).
• Is it enabled in the router settings? remote access (for some models).

6. Method 5: Check your ID in your provider's personal account

Some internet service providers (eg. Rostelecom, MTS, Beeline) display MAC address of the connected router in the subscriber's personal account. This is convenient if the device was issued by the provider itself.

How to find:

1. Log in to your provider's website (for example, lk.rt.ru For Rostelecom).
2. Go to the "My Devices", "Hardware" or "Connection Status" section.
3. Find the block with information about the router - it will indicate the MAC (sometimes called the "Hardware Identifier").

If the MAC address in your personal account does not match the one on the router sticker, it is possible:

• The provider uses your MAC for authorization (often happens with Dom.ru).
• It's enabled on the router. MAC cloning (function MAC Clone in the settings).
• Do you have double NAT (the router is connected via another router).

⚠️ Note: Providers' personal account interfaces are frequently updated. If you don't find the section you need, use the page search (Ctrl + F) and enter "MAC" or "identifier".

7. Common problems and how to solve them

When searching for a router ID, users encounter typical difficulties. Let's look at the most common ones:

If you changed the MAC address router (for example, to bypass provider blocking), but the Internet does not work, check:

• 🔄 Did you reboot your router after the changes?
• 📞 Does your provider block cloned MACs (for example, some do) Third Transport Ring, this is prohibited by the rules).
• 🔌 Is the format specified correctly (e.g. 00:1A:2B:3C:4D:5E, and not 001A.2B3C.4D5E).

FAQ: Answers to frequently asked questions

Is it possible to change the MAC address of a router?

Yes, most routers have this feature. MAC Clone (MAC cloning). It allows you to replace the original address with any other. However:

• Not all providers allow this (for example, MGTS may block the connection).
• After changing the settings, you need to reboot the router.
• Some models (eg MikroTik) allow you to change MAC only through the console.

To restore the original MAC, reset the router settings or disable it. MAC Clone.

What is the difference between a router's MAC address and a Wi-Fi MAC address?

The router has multiple MAC addresses:

• WAN MAC — used to connect to the provider (important for binding).
• LAN MAC — local network address (needed for filtering devices).
• Wi-Fi MAC — wireless module identifier (displayed as BSSID).

In most cases the provider needs WAN MAC, and to set up Wi-Fi - MAC of the access point.

How to find out the router ID if it is broken?

If the router does not turn on or does not respond:

1. Try to find the MAC sticker on the case (sometimes it is duplicated under the battery in 4G routers).
2. If your router was linked to a provider, request the MAC address from support (your passport or contract will be helpful).
3. For warranty repairs, please use serial number (It is often indicated on the receipt or box).

If the sticker is lost and the router is not working, you cannot restore the MAC address yourself. Contact a service center.

Should I hide my SSID for security?

Hiding the network name (Hide SSID) doesn't improve security, but only complicates connecting new devices. Instead:

• Use a strong password (at least 12 characters, with letters and numbers).
• Enable encryption WPA3 (or WPA2, If WPA3 (not supported).
• Turn it off WPS - This protocol is vulnerable to hacking.

A hidden SSID can still be found using specialized programs (for example, Wireshark), so it is a useless measure.

Is it possible to find out the router model using the MAC address?

Partially. The first 6 characters of the MAC (e.g. 00:1A:2B) are called OUI and indicate the manufacturer. They can be used to identify the brand, but not the specific model. For example:

• 78:59:3E — Keenetic.
• 50:C7:BF — TP-Link.
• D8:5D:4C — ASUS.

A full list of OUIs can be found on the website IEEE (enter first 6 characters of MAC).
