4.8 Updating Device Firmware
Symbol periodically releases updated versions of the access point device firmware to the Symbol
Web site. If the access point firmware version displayed on the
System Settings page (see
Configuring System Settings on page 4-2 ) is older than the version on the Web site, Symbol
recommends updating the access point to the latest firmware version for full feature functionality.
The access point’s automatic update feature updates the access point’s firmware and configuration
file automatically when the access point is reset or when the access point initiates a DHCP request.
The firmware is automatically updated each time firmware versions are found to be different
between what is running on the access point and the firmware file located on the server. The
configuration file is automatically updated when the configuration file name on the server is different
than the name of the file previously loaded on the access point or when the file version (on the server)
is different than the version currently in use on the access point.
Additionally, the configuration version can be manually changed in the text file to cause the
configuration to be applied when required. The parameter name within the configuration file is
“cfg-version-1.1-01.” The access point only checks the two characters after the third hyphen (01)
when making a comparison. Change the last two characters to update the access point’s
configuration. The two characters can be alpha-numeric.
NOTE Symbol recommends importing configuration files using the CLI. If errors
occur during the import process, they display all at once and are easier to
troubleshoot. The access point GUI displays errors one at a time, and
troubleshooting can be a more time-consuming process.
NOTE For a discussion on the implications of replacing an existing Symbol
AP-4131 deployment with an AP-5131 or AP-5181, see
Replacing an AP-4131 with an AP-5131 or AP-5181 on page B-20 .
