How to accurately identify your Wi-Fi modem model: from stickers to hidden commands

Did you buy a used modem on Avito, lose the router box, or simply forget what model you have? Without the exact device name, it's impossible to download firmware, find drivers, or even properly configure the network. In this article, we'll break it down. 7 working methodsHow to find out the model of your Wi-Fi modem – from the obvious (inspecting the case) to the hidden (special commands and system logs).

We will pay special attention to combined devices (router + 3G/4G modem in one case), where manufacturers often hide information about the mobile communication module. We'll also explain why. On some Huawei and ZTE modems, the data sticker may not match the actual "stuffing" of the device — and how to check it.

1. Inspect the case: where to look for the data sticker

The fastest way is to find the factory sticker. It is on any certified device, even if they tried to scrape it off. Search on:

• 🔹 Bottom cover (90% of routers and modems)
• 🔹 Back panel (for vertical models like TP-Link Archer C6)
• 🔹 Under the battery (3G/4G modems seem to have Huawei E3372)
• 🔹 Inside the SIM card compartment (for hybrid devices of the type ZTE MF286R)

Look for the following lines on the sticker: Model, Model No, Type or H/W Ver. For example: TL-WR841N Ver:6.20 - this is a model TP-Link TL-WR841N with hardware revision 6.20.

⚠️ Attention: On some modems (especially from Huawei And ZTE) the sticker may indicate serial number, not a model. For example, the inscription B525s-23a - this is a model, and SE1234567890 — serial number. Don't confuse!

2. Router web interface: where is the model information hidden?

If your modem is distributing Wi-Fi, connect to its network and log into the admin panel. Standard addresses: 192.168.0.1, 192.168.1.1 or 192.168.8.1 (at Huawei). The default login/password is usually admin/admin or indicated on the sticker.

Where to find the model in the interface:

If the interface is in English, look for the following lines: Hardware Version, Product Name or Device Model.

3. Command line: how to find out the model via Telnet/SSH

For advanced users: If you have access to Telnet or SSH (usually a port 23 or 22), you can run commands to obtain hardware data.

Connect to the modem (for example, via PuTTY) and enter:

cat /proc/cpuinfo | grep "machine"
uname -a
dmesg | grep "board"

Example output for TP-Link TL-WR841N: machine: TP-Link TL-WR841N ver 6.20

What to do if Telnet is disabled?

Many manufacturers block Telnet by default. You can enable it through the web interface (under "System Tools" → "Telnet") or using alternative firmware like OpenWRT.

⚠️ Attention: On some modems (for example, Huawei B315) SSH/Telnet access required unlocking Through the engineering menu. Inexperienced users are advised not to experiment, as there's a risk of bricking the device.

4. Programs for Windows/macOS: Network scanning

If the modem is connected to the computer via Ethernet or Wi-Fi, you can use network scanning software. These will show not only the model, but also the MAC address, IP address, and even the firmware version.

Top 3 utilities:

• 🔧 Advanced IP Scanner - shows the manufacturer by MAC address (free, official website)
• 🔧 Angry IP Scanner — scans ports and identifies devices (cross-platform)
• 🔧 Wireless Network Watcher — specializes in Wi-Fi devices (from NirSoft)

How to use: Download → Run scan → Find your modem in the list → Look in the "Manufacturer" or "Model" column.

Make sure the modem is connected to the network|Compare the MAC address with the sticker on the device|Check the "Vendor" column|Export the report to CSV for further analysis-->

5. Mobile applications: identifying the model via a smartphone

If you only have your phone at hand, install one of these apps:

• 📱 Fing (iOS/Android) — scans the network and displays device models
• 📱 WiFi Analyzer (Android) - Determines the manufacturer by MAC address
• 📱 NetScan (iOS) - displays detailed information about connected gadgets

Instructions for Fing:

1. Connect to your modem's Wi-Fi.
2. Launch the application and click "Scan".
3. Find your modem in the list (usually the first one in the list with IP 192.168.x.1).
4. Tap on it and information about the model will open.

⚠️ Attention: Applications define a model by MAC address database, which isn't always relevant. If you see "Unknown," try another method.

6. Engineering menu: hidden data for experienced users

On some modems (especially Huawei, ZTE, D-Link) there is a hidden engineering menu where detailed specifications are indicated, including the chipset model and antenna version.

How to get there:

1. In the browser address bar, enter: http://192.168.1.1/html/debug.asp (For D-Link)

   or

   http://192.168.8.1/html/debug.html (For Huawei).
2. If it asks for login/password, try admin/admin or telecomadmin/admintelecom (for Huawei).
3. Search sections Hardware Info or Device Tree.

Example of data from the engineering menu Huawei B525:

Product Family: B525
Hardware Version: CL1B525SM91
Software Version: 11.100.17.00.03

7. Visual identification: how to distinguish similar models

Sometimes the models differ only one letter (For example, TP-Link Archer C6 vs C6U), but they have different characteristics. Here's how to tell them apart:

Key visual cues:

• 🔍 Color and shape of the case: ASUS RT-AC66U - black with red inserts, and RT-AC68U - completely black.
• 🔍 Number of antennas: TP-Link Archer C20 - 2 antennas, C50 — 4.
• 🔍 Connectors: Huawei B535 has a port RJ-11 for the phone, and B525 - No.
• 🔍 Inscriptions on the front panel: ZTE MF286R has the operator's logo (for example, "MTS"), and MF286D - No.

If in doubt, compare your device with the photo on the manufacturer's official website or on Yandex.Market.

FAQ: Frequently asked questions about identifying your modem model

The modem won't turn on - how do I find out the model?

If the device does not respond to the power button, inspect power unit: often the model is indicated on it (for example, Input: 12V 1A for TL-WR841N). Also check ports: at ASUS they are usually blue, TP-Link - black.

The model number on the sticker is erased - what should I do?

Try wiping the sticker off. with a cotton swab and alcohol — sometimes this helps read the text. If it doesn't help, use the methods in the section about command line or engineering menu.

How to find out the actual model of your carrier's modem (MTS, Beeline)?

Operators often reflash devices to suit their brand. For example, MTS Connect 4G-2 - this is a re-made one Huawei B525To find out the original model:

1. Go to the web interface (192.168.8.1 for MTS).
2. Check the section System → Device Information.
3. Look for the line OEM Model or Original Model.

Is it possible to determine the model by IMEI?

Only modems with IMEI have mobile module (3G/4G/5G). You can check it:

1. On the sticker under the battery (if it is removable).
2. In the web interface in the section Status → Mobile.
3. Through the team AT+GSN V PuTTY (if AT commands are supported).

Then enter the IMEI on the website imei.info — the system will show the model.

How to distinguish a router from a Wi-Fi modem?

Router distributes the Internet connected via cable (Ethernet), and modem with Wi-Fi has a SIM card slot and can operate autonomously. Hybrid devices (for example, Huawei B535) combine both functions. Check:

• Is there a SIM card slot?
• Is there a port? WAN (for cable internet)?
• Is the indicator light on? 4G/5G?
