Best Practices for Chromecast and AirPlay
Using AirPlay and Chromecast on networks with more than 100 wireless clients may degrade performance due to the use of multicast traffic.
The following steps will optimize network performance:
- Enable Multicast and Broadcast Control on the WiFi serving 100+ clients.
- Note: This will break connectivity of other services using multicast or broadcast traffic unless you add them as "Exceptions."
- Create a new Network (VLAN).
- Create a new WiFi to broadcast the network.
- Connect all AirPlay/Chromecast clients to this new WiFi.
- Ensure Multicast Filtering is enabled for all networks used to broadcast WiFi.
