Draytek Vigor – TFTP Recovery for Repairing Or Updating Bricked / Faulty Routers
Introduction
This document shows how to upgrade or repair a Draytek Vigor router firmware with TFTP using a macOS device. The method uses Trivial File Transfer Protocol (TFTP) which is a useful fallback if your router’s firmware is broken and you cannot access the web management interface.
Method
Step 1
Connect your computer directly to the router’s LAN1 port and configure a static IP address on Mac OS device:
- Go to System Preferences > Network
- Configure LAN Adapter settings
- Static IP 192.168.1.10
- Subnet Mask 255.255.255.0
- Default Gateway: 192.168.1.1 (the default IP address of the router)
Step 2
Set the Vigor router to TFTP mode.
- Power off the router
- Press and hold the Factory Reset button
- Power on the router while still pressing down the Factory Reset button
- For Vigor3900, the ACT LED lights will flash rapidly
For most other Vigor models, the left three LED lights will flash rapidly
Step 3
Open your Mac’s web browser and download the latest firmware version for your model from https://www.draytek.co.uk/support/downloads
This will download a zipped folder to your Mac. Unzip the folder to your Desktop.
Step 4
On the Mac OS device, open Terminal and enter the following commands (do not enter the ” ” marks)
- “cd”
- Type a space after cd
- Drag the firmware folder to the window and the path will be pre-filled for you
- Press return
- “tftp 192.168.1.1”
- Press return
- “binary”
- Press return
- “put”
- Type a space after put
- Drag the firmware file out of the folder and into the Terminal window to pre-fill the path
- You will probably want to use the .rst file which completely resets the unit
- If you use the .all file it will retain existing settings, but this is not advisable if you have a faulty unit
- Press return
The result will be shown on Terminal after the file has been uploaded successfully.
Then the router will now reboot and return to normal operating mode.
