How to fix L-Acoustics Controller connection issues to the L-NET network?
If you're unable to connect your L-Acoustics Controller to the L-NET network (and the controller is not in “grey screen”), consider the following potential causes: * Offline mode might be selected on LA NWM. Ensure online mode is selected. * The scanning range might not include the controller IP address. Include the controller IP address in the scanning range on LA NWM. * There might be a wrong IP address or multiple controllers with the same IP address. Set the computer IP address and subnet mask as well as the controller IP address as indicated in the LA NWM video tutorial. * The L-NET cable might not be plugged in or might be plugged into the wrong L-NET connector. Plug and secure CAT5e U/FTP cables into the L-NET connectors on the controller to connect it to other controllers ...
