I have an installation with 5 En12-45 splitters in a congress building. These are connected to the main light controller through a switch in a dedicated VLAN. The controller sends out ArtNet in the 192.168.4.X range. They behave properly for a day or so before they stop working. When I then try to reach the webpage it says that it took to long to respond. The only thing helping is a restart of the splitters by turning them off and on.
I checked that there is no IP conflict and that the ports on which they are patched are tagged accordingly to the VLAN. The interesting thing is that when I ping them from a pc in the network I can’t find them, but if I scan the network with arp -a I am able to see them.
All switches are running the latest firmware.
Hope someone can help out.
