Add a task to the scheduler as shown below
| Note |
|---|
Make sure to complete these two tests successfully after installation: Run the script in a command shell while the PC is not connected to Merlin
➡️ The script must announce that it connects to WLAN now. Run the script in a command shell while the PC is connected to Merlin.
➡️ The script must inform that the PC is already connected to Merlin.
The two variants of the script provided for download use different mechanisms to identify, if the PC is already connected to Merlin. Make sure to use the script variant that successfully detects an existing Merlin WLAN connection. |

Run Task Scheduler |  |
Name the task and set it to run irrespeecive of user login. Click on Triggers. |  Image Added |
Add trigger for “At startup”. Click OK |  Image Added |
Add trigger to repeat task daily every 5 minutes. Note: the script doesn’t draw a lot of performance. This scheduled execution ensures, that the connection to Merlin is made irrespective of the sequence in which PC and Merlin are booted. Click OK |  Image Added |
Click on Actions |  Image Added |
Add action to start a programm. Enter the path to the script. Pass the name of the WLAN to the script as parameter. Note: The WLAN must be connected once manually to create a corresponding WLAN profile in Windows. See Merlin WLAN Koppelung for details on how to do that. |  Image Added |
