AP update

LANCOM WLAN Controllers allow the configurations of multiple LANCOM
Access Points to be managed from a central location in a consistent and con-
venient manner. With central firmware and script management, uploads of
firmware and scripts can be automated for all of the WLAN devices.
To achieve this, the firmware and script files are stored on a Web server
(firmware as *.upx files, scripts and *.lcs files). The WLAN Controller checks
once daily, or when prompted by a user, to compare the available files with
those on the devices. Alternatively, this procedure can be handled by a cron
job—overnight, for example. If an update can be carried out, or if the Access
Point is not running the desired firmware version, then the WLAN Controller
downloads the file from the Web server and uploads it to the appropriate
Access Points.
The configuration of firmware and script management provides precise con-
trol over the distribution of the files. It is possible, for example, to limit certain
firmware versions to certain device types or MAC addresses.
An update can be carried out in two possible states:
When a connection is established; the Access Point subsequently restarts
automatically.
If the Access Point is already connected, the device does not restart auto-
matically. In this case the Access Point is manually restarted with the
menu action "/Setup/WLAN-Management/Central-Firmware-Manage-
ment/Reboot-updated-APs" or by a timed cron job.
The action "/Setup/WLAN-Management/Central-Firmware-Management/
Update-Firmware-and-Script-Information" updates the script and
firmware directories.
