Using Wi-Fi and Multicast Transmit Flows

When using a Wi-Fi network connection between Dante Controller and your Dante network, any multicast
transmit flows configured in your network routing can flood the Wi-Fi link, and degrade the performance of
the link.
You may be experiencing this condition if:

1. You are using a Wi-Fi network connection
2. You have multicast transmit flows in place
3. You observe speed or stability issues with your Wi-Fi connection

Remedial action
Remove or reduce the multicast traffic
The easiest way to remedy this condition is to either remove all multicast flows and use unicast flows
instead; or, reduce the amount of multicast bandwidth on the network by removing some multicast flows.
There is no hard rule that specifies how much multicast traffic is too much for a Wi-Fi link – the performance
of the link is the best real-world indicator.
If you are unable to remove or reduce multicast traffic, there are various ways to filter multicast audio traffic
from the Wi-Fi link.
Filter multicast audio at the access point
Depending on the type of Wi-Fi access point (or AP - typically, a W-Fi modem / router) that you have, it
may automatically block ‘unregistered’ multicast traffic, which is multicast traffic that hasn’t been
specifically requested by a network device. Because Dante Controller will never request to join a multicast
audio stream, the AP will never send multicast audio to the Dante Controller computer.
It should however allow multicast control traffic – this is important for Dante Controller, because device
discovery in Dante uses a multicast control protocol.
