AirLive WHA-5500CPE User’s Manual 130
The WHA-5500CPE features an Emergency Recovery function in the bootloader to
recovery the AP in case of a firmware crashed. When you can’t access the
WHA-5500CPE, please first try to repower the CPE or restore the settings to default. You
should find the CPE at 192.168.1.1.
If it still can not solve the problem, you can try to recover the CPE using the method
described in this chapter. Do not power off the WHA-5500CPE or your PC during process.
Please read through this chapter carefully before attempting to perform the upgrade. If the
WHA-5500CPE is damaged by improper use of this procedure, it will void your warranty.
It is recommended to have your dealer or distributor performing this procedure.
10.1 How Emergency Upgrade Works
The WHA-5500CPE’s flash memory is divided into “firmware” and “bootloader” area. The
bootloader area will check if the AP’s firmware is crashed at each bootup. If it detects the
firmware is crashed, the AP will try to download the firmware file “zImage” from remote
TFTP server(with IP address 192.168.1.254) automatically. Therefore, you must prepare
a PC with TFTP server software before performing the upgrade procedure.
10.2 Emergency Upgrade Procedure
1. Set your PC’s IP address to 192.168.1.254 and connect your PC directly to the
WHA-5500CPE.
