Emergency Recovery
This document guides you how to inspect and repair your WHA-5500CPE firmware.
Under certain conditions your WHA-5500CPE firmware will crash. The most common situation
is loss of power during the updating firmware process, resulting in not being able to power on.
You can try the following steps to see if the firmware is damaged or not:
1. At local area, ping your WHA-5500CPE IP address
2. Try using telnet to login to WHA-5500CPE
3. Try login to your WHA-5500CPE’s Web UI
It might be possible that the IP address of the WHA-5500CPE has been changed. Please
manually reset your WHA-5500CPE to factory default setting IP address as 192.168.1.1 and
repeat the above three steps to confirm firmware.
Once the setup is powered on,
press the Reset button and
hold for 5 seconds. The setup
will then reset to factory
default setting.

In our design, every time when the WHA-5500CPE turns on, the bootloader will automatically
check if the firmware inside the memory is complete. If the firmware has no problem, the
WHA-5500CPE will load the firmware inside the memory. If the firmware inside the memory is
damaged, then WHA-5500CPE will automatically search the Internet for the computer, and
update the new firmware through the computer.
To complete automatic updating to the firmware, we must prepare the following things.
1. WHA-5500CPE and other computer accessories.
2. PC or Laptop (Microsoft Windows operating system), set IP address as
192.168.1.254/255.255.255.0 (To avoid confusion, we don’t recommend setting multiple IP
addresses)
3. WHA-5500CPE firmware, you can download it from here
http://www.airlive.com/support/WHA-5500CPE/fd_wha_5500cpe.shtml , and name the file as
zImage (Note: Only this file name can be used) and save it to C: drive (to avoid confusion,
please don’t save the firmware file to any other drive, or else it won’t work)
4. TFTP server software, we suggest tftpd32 http://tftpd32.jounin.net/tftpd32_download.html,
please place in C: drive to execute this command.

Please follow the following steps to operate:
1. Check if the WHA-5500CPE firmware is located in the C: drive.
2. Check your computer IP is set as 192.168.1.254/255.255.255.0
3. Check to see if your computer is connected with WHA-5500CPE
4. Execute the TFTP server software in your computer drive.
5. Let the WHA-5500CPE connect to a power source.
6. From your TFTP command session, you can see WHA-5500CPE reading the firmware in
the C: drive.

7. It takes around 5 minutes to download firmware and around 5 minutes to update the
firmware.
7. After a successful recovery, the WHA-5500CPE boots up automatically.
8. Try ping or access 192.168.1.1 by an internet browser,
9. Repeat the processes again if failed.
