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.
