The WLZENT03 performs a cyclical check for updates to the operating system and the Wireless-Pro software. The WLZENT03 requires an Internet connection for this check. 


The WLZENT03 automatically checks for updates once a week (Sundays, 0:00 a.m.), downloads them automatically and installs them. This update process does not require any manual intervention. However, it is possible to start the search and installation of updates manually at any time, regardless of the weekly rhythm described above. To do this, click on the “Check for updates” command in the Start menu under Miscellaneous.


Note: It may be necessary for your IT administrator to enable the update server in the firewall. 

Important: From time to time, the operating system itself displays an icon in the bar at the top of the screen to indicate that an update is available and allows it to be installed by clicking on the icon (see image below). 

For technical reasons, however, an update installed in this way will be lost when the system is restarted.

Therefore, an update must NOT be carried out via the icon, but ONLY via the “Check for updates” command in the start menu. 


It can happen that individual operating system updates are not installed. In this case, the update icon remains or reappears. This is not a malfunction, but intended behavior. In such a case, the update icon should be ignored. 



Note: An offline update of the operating system is not provided, nor is the subsequent installation of software, e.g. via USB stick on the device.
