If your computer is connected
to several networks simultaneously, this may cause the issue. A common
situation is that you are connected to 1 WIFI and 1 ethernet network. Please
disconnect from the network your fixtures are not connected to and try reach them
again with System Assistant.
Network setup or security
You may have unknown settings
in your existing network causing the issue. To examine if this is the case, you may try setup/connect a very simple network including 1 laptop, 1 fixture and 1 router. Connect all with Ethernet cables and set both your fixture and
router to dynamic IP. Now please try reach the light with System Assistant
again. If it still doesn’t work, do a factory reset of the light fixture.
