Artnet device doesn't receive data from Beam

Hi,
I try to control some par lights using Beam for Live or Beam for Max with an Artnet to DMX convertor. The Artnet device is connected to my Macbook with an ethernet cable through an ethernet adapter. I changed the IP address of the LAN connection (192.168.1.99) according to the IP address of the Artnet device (192.168.1.100). I created an Art-net output in Beam with IP address 192.168.1.99, set the Target Universe to 0 while the source Universe being 1, and added some fixtures in the Universe 1 according to the profile of my lights. However, my Artnet device can never receive anything from Beam for Live or Beam for Max. I did exactly what I should do to send messages, and I tried the Test function in both Beam for Live or Beam for Max. Never worked.
However, when I use Madmapper with the same settings (IP address, Universe, DMX address) and the same device, it works well. I tried with another Mac and got the same result: Madmapper works while Beam does not. Does anyone have similar experiences or have any ideas about what might be the problem? It’s my first time using Beam and it would be very helpful if I can use it to control lights from Max or Live.

Hi! It sounds like you took the right steps. One thing we could check is whether Beam sends ArtNet over a WiFi connection instead of LAN. Could you try turning off WiFi and make sure there are no other active network adapters besides the LAN connection?
