A Wi-Fi router's version isn't just a string of numbers on the case. It determines firmware compatibility and support for new standards. Wi-Fi 6/6E, maximum connection speed and even resistance to vulnerabilities such as Krack or FragAttacks. For example, TP-Link Archer C7 v2 And v5 are identical in appearance, but the first one only supports Wi-Fi 4 (300 Mbps), and the second one is Wi-Fi 5 (867 Mbps). Without the exact version, you risk downloading the wrong firmware, which could brick your device.
The problem is that manufacturers often release the same model in 3-7 revisions, changing only the internal components (chipset, memory, antennas). However, only the base model is indicated on the box and in the documentation—for example, ASUS RT-AX55, although in reality you may have RT-AX55 V2 with a different processor. In this article, we'll cover all the ways to determine the exact router version, including hidden methods for devices without stickers or with a damaged interface.
1. The fastest way: a sticker on the router body
On 90% of routers, the version is indicated on the factory sticker, usually located on the bottom panel. Look for markings like:
- 🔍
Model: TL-WR841N v12(at TP-Link) - 🔍
RT-AC66U_B1 Rev. A1(at ASUS) - 🔍
KN-1010 HW: 1.2(at Keenetic) - 🔍
DIR-825 B1(at D-Link)
If the sticker is worn off or missing, check:
- 📦 The router box — the version is often duplicated on the barcode label.
- 📄 Warranty card or instructions - in some models (for example, Zyxel Keenetic) the version is indicated on the first page.
- 🖨️ Check or invoice — in online orders, the version can be specified in the article number (for example,
MI-R3G-V2For Xiaomi Mi Router 3G).
⚠️ Attention: Some brands (eg. Mercusys or Tenda) the version can be designated by letters -MR60 vAorAC10U EUThis is not a hardware revision, but a regional modification (EU - Europe, RU - Russia, US - USA). The digital version is important for flashing (v1,v2).
2. Via the router's web interface: where to look for the version
If the sticker is unavailable, logging into the admin panel is the most reliable option. Connect to the router via cable or Wi-Fi, then:
- Open your browser and enter the following in the address bar:
- 🌐
192.168.0.1(For TP-Link, D-Link, Tenda) - 🌐
192.168.1.1(For ASUS, Zyxel, Mercusys) - 🌐
my.keenetic.net(For Keenetic)
- 🌐
admin/admin or see sticker).| Brand | Path to the menu | Example of version display |
|---|---|---|
| TP-Link | Advanced → System Tools → Firmware Upgrade |
Hardware Version: Archer C6 V3 00000000 |
| ASUS | Administration → System |
Model Name: RT-AX58U B1 |
| Keenetic | General Settings → Device |
Model: KN-1810 HW: 1.1 |
| D-Link | System → Device Info |
Hardware Version: DIR-842 C2 |
| Zyxel | System → Information |
Model: NBG6617 Rev.2 |
If there is no explicit version indication in the interface, try:
- 🔎 Find a section
StatusorSystem Log— sometimes the version is written in the logs during loading. - 🔎 Export settings (for example, to TP-Link:
Advanced → System Tools → Backup & Restore). In the configuration file (.cfgor.bin) may be a string with a version.
☑️ Check the version via the web interface
3. Mobile apps: convenient, but not always accurate
Router manufacturers release official apps that automatically detect the device's model and version. The advantage of this method is that you don't need to search for stickers or navigate the web interface. However, there are some caveats:
- 📱 TP-Link Tether - shows the version in the section
Device → Information, but sometimes it only displays the base model (eg Archer C20 withoutv4). - 📱 ASUS Router - the version is indicated in
Settings → System, but for older models (for example, RT-N12) may not be displayed. - 📱 Keenetic — in the application the version is indicated as
Hardware revision(For example,HW: 1.3). - 📱 Mi Wi-Fi (For Xiaomi) - version hidden in
About the device → Hardware version, but is often absent in clones.
The problem with mobile apps is that they may not support outdated models. For example, D-Link DIR-300 or Tenda N301 They simply won't appear in newer versions of the app. In this case, use the web interface.
⚠️ Attention: Third party applications (eg. WiFi Analyzer or Fing) determine only router model, but not its hardware version. This data is useless for flashing or repairing.
4. Command line: for advanced users
If the router supports Telnet or SSHYou can check the version via the command line. This method is useful if the web interface is blocked or damaged. Instructions:
- Activate Telnet/SSH in the router settings (usually in the section
Administration → SystemorSecurity). - Connect via the program PuTTY (Windows) or terminal (Linux/macOS):
ssh admin@192.168.1.1Enter the same password as for the web interface.
- Run one of the commands (depending on the firmware):
cat /proc/cpuinfo | grep "machine"dmesg | grep "Hardware"
nvram get hardware_version
Output examples:
- For TP-Link:
machine: TL-WR841N v14 - For ASUS:
Hardware: RT-AC68U Rev. A2 - For OpenWRT:
hw.revision=0x102 → v2(need to be decoded according to documentation).
If the command line is not available, try connecting via serial console (requires opening the case and special equipment). This method is used to restore bricked routers.
What to do if the router does not respond to SSH/Telnet?
If the router does not respond to the connection, check:
1. Is the service enabled in the settings (Administration → Services).
2. Is the firewall blocking the connection (disable it temporarily).
3. Are you using the correct IP address (check via ipconfig in Windows or ifconfig in Linux).
If nothing helps, reset the router to factory settings using the button Reset (hold for 10-15 seconds).
5. By MAC address: a rare but working method
Each router is assigned a unique MAC address, which can be used to determine the model and sometimes the version. This method is suitable if you don't have access to the device itself (for example, if the router is installed in another city).
How does this work:
- Find out the MAC address of your router:
- 🖥️ On Windows:
ipconfig /all→ searchDefault GatewayAndPhysical Address. - 🐧 On Linux/macOS:
arp -aorifconfig. - 📱 In a mobile app (for example, Fing): scan the network and find the gateway MAC.
- 🖥️ On Windows:
B0:48:7A) in the database MAC VendorsThis will show the manufacturer.B0:48:7A:xx:xx:xx → Archer C7 v2
9C:97:26:xx:xx:xx → TL-WR841N v13
The downside of this method is that not all brands publish such tables. For example, ASUS And Keenetic do not bind versions to MAC addresses, so the method only works for TP-Link, D-Link and parts of models Tenda.
6. Alternative methods: when nothing helps
If your router won't turn on, the sticker is worn off, and the web interface is inaccessible, try:
- 🔧 Disassemble the case - there is often a version marking on the board (look for the inscriptions
PCB: v1.2orHW: 3.0next to the processor). - 📦 Find the original box - on some models (for example, Netis) the version is indicated on the label with a barcode in the format
WL-XXXXXX/XX V2. - 🛒 Check your receipt or purchase history - in online stores (for example, AliExpress, DNS) the version can be indicated in the article number or product description.
- 📷 Take a photo of your router and use image search (Google Lens, Yandex.Images) - sometimes this way you can find an exact match with the specified version.
For routers without obvious markings (for example, operator models from Rostelecom or Beeline) the version may be embedded in the firmware. In this case:
- Download the firmware for the intended model from the official website.
- Open the file
.binor.trxin a text editor (for example, Notepad++ or HxD). - Look for lines with
hw_versionorboard_id- they may contain a version.
⚠️ Attention: Some operator routers (for example, Sagemcom F@st from Dom.ru) have unique versions that don't match the retail models. In this case, you'll need to use the files provided by your provider for flashing the firmware.
FAQ: Frequently asked questions about router versions
Is it possible to flash a router with firmware from a different version?
No! The firmware is strictly tied to the hardware revision. For example, the firmware for TP-Link TL-WR841N v11 not suitable for v12, even if the models are externally identical. Consequences range from boot failure to physical damage to the flash memory.
The exception is universal firmware like OpenWRT or DD-WRT, but they also require an exact match board_id.
How can I find out the router version if it won't turn on?
If the router does not respond to power:
- Check the power supply (the voltage should match the label).
- Connect to it via serial console (requires a soldering iron and USB-TTL adapter).
- Contact the service center - they can read the version from the board.
If the router turns on but does not assign an IP address (only the power indicator is on), try resetting the settings using the button Reset (hold for 30 seconds).
Why is there no firmware for my version on the manufacturer's website?
This could mean:
- 🔹 Your version is outdated and no longer supported (applies to routers older than 5–7 years).
- 🔹 The manufacturer has combined firmware for several versions (for example, ASUS RT-N66U B1/B2 use one file).
- 🔹 Your router is an OEM version for the operator (for example, Huawei HG8245H from MTS), and the firmware is released by the provider, not the manufacturer.
Solution: Contact the brand's support team with a photo of the sticker and request firmware.
How to distinguish a fake from an original router?
Counterfeit routers (especially popular models) TP-Link, Xiaomi, Tenda) often have:
- 🚩 Incorrect version marking (for example,
v99instead ofv5). - 🚩 No certification sticker (signs)
CE,RoHS,FCC ID). - 🚩 Low quality plastic (gaps, uneven seams).
- 🚩 The MAC address does not match the manufacturer's database.
Check the serial number on the brand's website - genuine devices are usually registered in the support system.
Is it possible to upgrade the hardware version of the router?
No, hardware version (v1, v2) is determined at the production stage and does not change. However, it is possible:
- 🔧 Update firmware (software) to the latest version for your revision.
- 🔧 Replace antennas or power unit to more powerful ones (if supported by the model).
- 🔧 Install alternative firmware (OpenWRT, DD-WRT) to expand functionality.
