If you already tried resetting your device to factory default values with the reset button and you can't access the unit, you can perform a reset using TFTP Recovery.
- airFiber device to upgrade.
- A narrow tool to press down reset button (like the pin of a headset or paper clip).
- An Ethernet cable.
- TFTP client running on PC.
- Take note of what airFiber firmware the device was running. You will have to use that same firmware for TFTP and once recovered, perform a regular upgrade via the WebUI to the latest AF firmware (firmware files downloadable here).

By reloading fresh firmware to restore the device, this process can also be useful to recover devices that have appeared to fail when no other solution is working. The firmware used is dependent on the firmware compatible with the product, and the version (use the same version as what the device was last running and then upgrade to the newest one available).
Steps: Recovery Procedure for Windows
1. Power off the device.
2. Configure your computer: Windows PC's Ethernet must be configured manually with the following settings (under Network Connections):
IP Address: 192.168.1.254, Subnet Mask : 255.255.255.0
3. Connect your airFiber unit to the PC using the Config port.
4. Begin by pressing the reset button. While holding button down, power the unit on. Wait 8 seconds then release the button (if you want to reset the unit to factory defaults, wait at least 15 seconds). Signal LEDs will be lit indicating that the device is ready for recovery.
5. Make sure that radio responds to pings (perform a ping 192.168.1.20 from a DOS window), if it does not, go back to the first step.
6. Upload firmware image file .bin to 192.168.1.20, using a TFTP client software (binary mode). Windows integrated command line TFTP client or download a third party utility to upload the airOS firmware. For example:
From Windows PC, you can use TFTP command line from a DOS window (
START>>>CMD). Go into the same directory structure as the firmware (e.g., assuming that you have stored the image files in c:\firmware directory, type the command :
cd c:\firmware) and enter the following (for help type TFTP -h):
tftp -i 192.168.1.20 put AF5X.v4.0.3.bin
7. Signal LEDs will keep blinking one by one in 4 different colors during firmware upgrade. Wait for about 7-10 minutes (devices and firmware depending). Do not power off the device during the procedure.
Steps: Recovery Procedure for Linux
Generic Linux distributions have an integrated command line TFTP client. From a PC running Linux, you can upload via TFTP by typing into Terminal the following commands:
tftp> put WA.v22.214.171.124727.180118.1314.bin

Once the device is back online, remember to upgrade to the latest firmware via the WebUI.
