Hi,

i just spot a possible bug in ArtNet plugin:
On a linux box, when used with wifi activated and connected to the LAN, device on network are not seen. If we wire connect the same box on the same LAN devices are detected and that's works fine.

Hello,

Are you sure the artnet devices are really present on the wireless network ?

EDIT- There are a ton of possible network configurations with what you've described. Are the wired network and the wireless network the same subnet ?

Ok some more informations:

yes wired and wireless networks are on the same subnet.
To be more precise the setup is this one:
- an Openwrt device with wifi
- WAN not connected
- connected to wired LAN: usually 2 Rasp with each ones to LEDs strips, one enttec OPEN DMX ETHERNET and the laptop for running QLC+
- connected to WIFI: one android device running ARTNet https://sites.google.com/site/artnetcontroller/ controller used to setup alls my fixures.

So the bug appear when I switch my laptop from wired lan to wifi: in QLC+ I can't see any of the device on the lan. But testing, on the laptop with tools from libartnet project (artnet_discover) https://www.openlighting.org/libartnet-main/ every device where seen fine and values can be changed.
puting it back to wired network and it's worked fine....

for qlc+ i use the git version fron Linux automated builds and is running on a ubuntu 14.04 distribution.

I don't know when this bug appear as most of the time I don't use control through wifi but I have it working in a past version, probably before the introduction of lo interface in the set of interfaces

Some routers have security options to configure wireless client isolation. That prevent wireless clients see each others on the same wifi that not occurs if client is wire connected.
