LANCOM WLAN Controllers allow the configurations of multiple LANCOM Wireless Routers and LANCOM Access Points to be managed from a central location in a consistent and convenient 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 on user request, 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 Wireless Routers and Access Points.
The configuration of firmware and script management provides precise control 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 automatically. In this case the Access Point is manually restarted with the menu action "/Setup/WLAN-Management/Central-Firmware-Management/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.
The parameters for configuration can be found under the following paths:
LANconfig: WAN Controller / AP Update
WEBconfig: Setup / WLAN Management / Central Firmware Management
