While not officially supported... it can be possible to make a client/mirror connection work over WiFi if everything is configured properly. Obviously this is not something you should count on for anything show-critical, and I would second Abby's suggestions for anything important. I don't want to make her job too much harder by giving people silly ideas
If you can take the same laptop and successfully make a wired connection, then the most common problem is that your
network isn't allowing multicast packets (used for device discovery) to pass to the wireless side. If you have a consumer-level device (combined
WAP,
switch, and
router), then connecting to the wired
network using the "Internet" port will definitely
block multicast. If not that, then there may be filters configured somewhere else in the
system. This gets into some pretty complex
network stuff, but I would generally set it up so that streaming protocols (
sACN,
Art-Net,
etc) are blocked from Wi-Fi, but other kinds of multicast are allowed. Maybe someone decided to be more aggressive and
block all multicast traffic.
