Updating the firmware of your Tenda N301 v6.0 router can resolve performance issues, such as bandwidth bottlenecks, and patch security vulnerabilities like CVE-2023-29680, which allows attackers to intercept login credentials. Preparing for the Update
Before you begin, ensure you have the correct file for your hardware version, as installing incompatible firmware can permanently damage the device.
Identify Hardware Version: Check the label on the bottom of your router to confirm it is indeed v6.0.
Current Firmware: Log in to the admin panel to check your current version. Version V12.02.01.72 is a recent update for specific v6.0 regional variants.
Wired Connection: Always perform the update via an Ethernet cable rather than Wi-Fi to prevent failure if the wireless connection drops during the process. Step-by-Step Update Process
Download the File: Visit the official Tenda Download Center and search for "N301".
Extract the File: The download will likely be a .zip file. Use software like WinRAR or 7-Zip to extract it; you will need the file ending in .bin or .trx.
Access the Admin Panel: Open a web browser and go to 192.168.0.1. Use the default password admin if you haven't changed it.
Navigate to Upgrade: Go to System Settings (or Administration) and then click on Firmware Upgrade.
Upload and Upgrade: Click Select a file (or Local Upgrade), choose the .bin file you extracted, and click Upgrade.
Do Not Power Off: Keep the router powered on throughout the progress bar. It will reboot automatically when finished.
Factory Reset: Tenda strongly recommends performing a factory reset after the upgrade to ensure all new settings apply correctly. Troubleshooting "Hot" or Performance Issues
If your router is running "hot" or experiencing lag, it may be under heavy load or poorly ventilated.
Airflow: Ensure the router is on a hard, flat surface away from heat sources. Avoid enclosed cabinets or soft surfaces like couches.
Optimize Settings: To reduce CPU load and heat, use a 20 MHz channel bandwidth for the 2.4GHz band and schedule a nightly restart.
Security Check: If your router is unusually hot and slow, ensure you have updated to at least V12.02.01.61 to patch credential interception vulnerabilities.

Step 4: Post-Update Reset (Cold Reset for Hot Router)
After the update, the old configuration may carry over heat-inducing bugs. Perform a factory reset:
- With the router powered on, use a paperclip to press the Reset button (small hole on the back) for 10 seconds.
- Release when all LEDs blink simultaneously.
- The router will restart. Now it is running pure new firmware.
Step 2: Backup Your Settings
Navigate to System Tools → Backup/Restore and click Backup. Save the .cfg file to your desktop. This allows you to restore your Wi-Fi name/password after the update.
Preventing Future Overheating (Even with New Firmware)
- Elevate the router – Use adhesive rubber feet to raise it 1cm from the desk.
- Don’t stack – Keep at least 2 inches of clearance on all sides.
- Schedule a weekly reboot – In the firmware, go to System Tools → Reboot Schedule and set it for 3 AM every Sunday.
- Limit connected devices – Disconnect idle phones/tablets.
- Disable WPS – WPS probing generates extra heat. Turn it off under Wireless → Security.
Firmware Update Importance
Updating the firmware of your router is crucial as it enhances the device's performance, security, and functionality. Firmware updates can fix bugs, patch security vulnerabilities, add new features, and improve compatibility with various devices.
Signs That the Firmware Update Fixed the Overheating Issue
Within 1 hour of the update and reset, you should observe:
- Cooler chassis – The top surface is merely lukewarm.
- Stable LEDs – No random blinking or reboots.
- Consistent speed – Ping to 192.168.0.1 stays below 2ms.
- No more “hot” smell – Some users report a slight burning odor before update; that should vanish.
How to Check Your Current Firmware Version
Before updating, verify you actually have the V6 hardware revision (not V1, V2, or V5). The wrong firmware will brick your router.
- Connect your PC to the router (Wi-Fi or Ethernet).
- Open a browser and go to
192.168.0.1(default Tenda IP). - Login (default username/password:
admin/admin). - Go to Advanced → System Tools → Firmware Upgrade.
- Note the Current Firmware Version (e.g., V6.01.10_07_EN).
- Also check the Hardware Version printed on the sticker underneath the router – it must say “N301 V6”.
