How to Determine Exactly Which Router is Sharing Your Wi-Fi: From the Label to Hidden Commands

Have you ever found yourself in a situation where you urgently need to reconfigure your network but can't remember the exact router model sitting in your closet? Or moved into a new apartment where the previous tenants left behind working Wi-Fi but no documentation for the equipment? Determining the router model — this is the first step when diagnosing internet issues, changing a password, or optimizing coverage. Without this information, you won't be able to access the admin panel, update the firmware, or even purchase a compatible repeater.

In this article we will look at 7 working methodsHow to find out your router's model—from basic (inspecting the case) to advanced (analyzing the MAC address and network packets). You'll learn what data can be extracted without accessing the device itself, how to decipher factory labels, and which apps automate the process. And for those who appreciate precision, we've prepared a table of popular models and their MAC prefixes.

Spoiler: If your router gives out TP-Link, ASUS or Keenetic, the chances of identifying its model based on network data are 80% higher. However, with Chinese "no-name" devices, you'll have to tinker with them—but there are solutions for them too.

1. Inspect the case: where to find the model number on the router itself

The most obvious, but often overlooked way is physical inspection of the deviceEven if the router is hidden behind furniture or suspended from the ceiling, take 5 minutes to approach it with a flashlight. The data you need is usually located on bottom or rear panel in the form of a sticker (sometimes under the battery compartment, if it is a mobile router).

What exactly to look for on the label:

• 🔍 Model or Model - direct indication (for example, TL-WR841N For TP-Link or RT-AX88U For ASUS).
• 📋 S/N (serial number) - sometimes contains encrypted information about the model (first 4-6 characters).
• 🌐 MAC Address — by the prefix (the first 3 bytes) you can determine the manufacturer (see table below).
• 🔗 SSID by default - some brands include the model in the network name (eg KEENETIC-1234).

⚠️ Attention: On some devices (especially from providers like Rostelecom or Beeline) the sticker may be re-glued or erased. In this case, look for barcode - its decoding through online services (for example, Barcode Lookup) sometimes gives out a model.

If the router is high up or inaccessible, try taking a photo of the sticker at maximum zoom and then zooming in on your computer. Even a smartphone with a Wi-Fi mode will do. Macro or Document.

2. Data from the router admin panel

If you have network access (even as a guest), you can access the router's web interface and view information about it directly. To do this:

1. Find out Gateway IP address:
   • 🪟 On Windows: open Command line (Win+R → cmd) and enter

     ipconfig | findstr "Default Gateway"

   • 🍎 On MacOS: V Terminal complete

     netstat -nr | grep default

   • 📱 On Android/iOS: use apps like WiFi Analyzer or Fing (section "Gateway").

Enter the received IP (usually 192.168.0.1, 192.168.1.1 or 10.0.0.1) in the browser's address bar.

Log in (see default logins/passwords) in the FAQ).

Search section Status, System or About — there will be a model, firmware version and serial number.

⚠️ Attention: If the router gives an authorization error, and the standard admin/admin If your password doesn't work, don't try to guess it—it may lock your device. Instead, use the methods in the following sections.

On some firmware (for example, OpenWRT or DD-WRT) information about the model may be hidden behind a tab Advanced or in the command output

cat /proc/cpuinfo

(available via SSH).

3. Mobile applications for network scanning

If physical access to the router is limited and the password for the admin panel is unknown, help will come mobile utilitiesThey analyze network traffic and metadata to determine the device model. The best options are:

• 📱 Fing (Android/iOS) - shows the router manufacturer by MAC address, and sometimes the model (in the section Devices → Gateway).
• 🔍 WiFi Analyzer (Android) - in mode AP List displays the hardware vendor (e.g. Xiaomi Communications).
• 🍎 Network Analyzer (iOS) - Scans ports and can provide firmware information if the router is vulnerable to UPnP.
• 🛡️ Router Checker (Android) — specializes in identifying router models based on traffic signatures.

Example of work Fing:

1. Connect to a Wi-Fi network.
2. Launch the application and wait for the scan.
3. Find the device with the gateway IP in the list (usually the first one).
4. Click on it - there will be a line in the details Vendor (manufacturer) and sometimes Model.

⚠️ Attention: Applications define a model only if:

• The router does not hide its signature (many Chinese devices do not do this).
• The application database contains data about your model (relevant for new devices).
• You are not using a VPN - it may distort the scan results.

How to trick the app if the router is not detected?

Some utilities (eg. Fing) allow you to manually add a router model to their database. To do this:

1. Find the MAC address of the gateway (via ipconfig or in the application itself).

2. Go to the website MAC Vendors and check the manufacturer by the first 6 characters of the MAC.

3. Manually match the data in the application if there is an "Edit Device" option.

4. MAC Address Analysis: Manufacturers Table

Each network device is assigned a unique MAC address, the first 3 bytes (6 characters) of which indicate the manufacturer. Knowing this prefix can help narrow down the model search. For example:

• 00:0C:43 — ASUS
• 78:59:3E — TP-Link
• 00:1E:58 — D-Link

Below is a table of popular prefixes and their corresponding brands:

How to find out the MAC address of a router:

1. On Windows:

   arp -a

   (look for the gateway IP in the output).
2. On Linux/MacOS:

   arp -n | grep "gateway_IP"

3. On Android: use WiFi Analyzer → AP List → BSSID.

If the first six characters of your router's MAC address don't match any of the prefixes in the table, it's most likely an OEM device (rebranded for a provider). In this case, try the methods in Section 5.

5. Advanced Commands: Telnet, SSH, and SNMP

If you are not afraid of the console, you can try to get data about the router through network protocolsThese methods work even if the web interface is blocked or hidden.

Method 1: Telnet/SSH (if enabled)

1. Check if the port is open 23 (Telnet) or 22 (SSH) to the router IP:

   telnet 192.168.1.1

   or

   ssh admin@192.168.1.1

2. If the connection is successful, enter the standard login/password (see FAQ).
3. Run the commands:

   cat /proc/cpuinfo

   (for Linux firmware)

   or

   show system

   (For MikroTik).

Method 2: SNMP requests

1. Install the utility snmpwalk (Windows: Net-SNMP, Linux: sudo apt install snmp).
2. Execute the query:

   snmpwalk -v 2c -c public 192.168.1.1 1.3.6.1.2.1.1.1.0

   (Where public — standard community, may differ).

3. In the answer, look for lines with sysDescr — the model is often indicated there.

⚠️ Attention: These methods require:

• Enabled services on the router (many providers disable Telnet/SSH by default).
• Knowledge of standard passwords (for example, for ZTE this is often admin/telecomadmin).
• Lack of a firewall blocking requests.

6. Definition by network characteristics

If all the previous methods didn't work, you can try indirect definition Network behavior models. This method is less accurate, but sometimes helps narrow the search.

What to analyze:

• 📶 Wi-Fi bands:
  • Only 2.4 GHz - old model (for example, TP-Link TL-WR740N).
  • 2.4 + 5 GHz - modern dualband router (ASUS RT-AC66U).
  • 6 GHz — flagship of 2023+ (Netgear Nighthawk RAXE500).
• 🔌 Ports on the case:
  • 1x WAN + 4x LAN - standard configuration (D-Link DIR-825).
  • 2x USB + SFP - advanced model (Keenetic Giga).
  • Button WPS - most devices before 2020.
• 🔗 Connection speed:
  • To 100 Mbps - an outdated model with Fast Ethernet.
  • 1 Gbps - a modern router with Gigabit LAN.
  • 2.5 Gbps and above - top-end device (ASUS RT-AX89X).

For analysis use:

• 📱 On Android: WiFi Analyzer (chapter Channel Graph).
• 🪟 On Windows: InSSIDer (shows channel width and Wi-Fi standards).
• 🍎 On MacOS: utility Airport Utility (Alt+click on the Wi-Fi icon).

⚠️ Attention: This method isn't 100% accurate, but it does help rule out obviously incompatible models. For example, if your router is distributing Wi-Fi 6 (802.11ax), then it's definitely not TP-Link TL-WR841N (which only supports 802.11n).

7. Contacting your provider: when nothing helps

If the router was provided by an Internet provider (for example, Rostelecom, MTS or Beeline), its model can be found out:

• 📞 Call the hotline (tell them you need to reconfigure the network).
• 🌐 In personal account on the provider's website (section "Equipment" or "My devices").
• 📧 In the contract or acceptance certificate - sometimes the model is indicated in the attached documents.

⚠️ Attention: Providers often use rebranded devices (eg. Sercomm under the brand Rostelecom). In this case, the model on the sticker and in the documentation may differ from the actual one. Check with support. original title to search for firmware.

If you purchased the router yourself but lost the receipt, check:

• 📅 Date of purchase in the bank statement (search by transactions with the store name).
• 📦 Box — even if it was thrown away, the photo could have been saved in the cloud (Google Photos, iCloud).
• 🔧 Warranty card - sometimes linked to a serial number, which can be used to restore the model.

FAQ: Frequently Asked Questions

How can I find out the default password for my router if I don't know the model?

Try these versatile combinations:

• admin / admin - for most TP-Link, D-Link, Tenda.
• admin / (empty) - for some ASUS And Zyxel.
• user / user or root / (empty) — for devices with firmware OpenWRT.
• telecomadmin / admintelecom — for routers from Rostelecom.

If nothing works, reset the router to factory settings (button Reset for 10 seconds) and use the data from the sticker.

Is it possible to determine the router model by the Wi-Fi network name (SSID)?

Sometimes yes. Some manufacturers include the model number in the default network name:

• KEENETIC-1234 → series Keenetic (the exact model is unknown).
• TP-LINK_0123 → router from TP-Link, but the model needs to be refined in other ways.
• MiWiFi_R4A → Xiaomi Router 4A.

If the SSID is changed by the user, this method will not work.

What should I do if the router doesn't have a sticker or it's worn off?

In this case:

1. Try methods with MAC address or mobile applications (sections 3 and 4).
2. If the router is turned on, look at indicators:
   • 🟢 Green light 5G — supported 802.11ac or ax.
   • 🔴 Red Internet - perhaps this is a model with GPON (For example, Huawei HG8245H).

Disassemble the case (if not under warranty) - the model may be printed on the board.

How to distinguish a router from a modem or ONT terminal?

Key features:

Device type	Ports	Indicators	Example of a model
Router	1x WAN + 4x LAN + sometimes USB	Wi-Fi, LAN, WAN	TP-Link Archer C7
Modem (ADSL/4G)	1x Ethernet + connector for telephone cable or SIM card	DSL, 3G/4G, Signal	D-Link DSL-2640U
ONT terminal (GPON)	1x PON (fiber optics) + 1-4x Ethernet	PON, LOS, Power	Huawei HG8245H

Is it possible to determine the router model by IP address?

No, the IP address itself does not contain any information about the model. However, internal IP (For example, 192.168.100.1) we can make assumptions:

• 192.168.1.1 - most home routers.
• 192.168.0.1 - some models D-Link And Netgear.
• 192.168.100.1 — often used in devices from providers (GPON terminals).
