- Chromecast is not streaming over wireless
- Chromecast utility is not able to locate the Chromecast device
This can be caused by the UPNP Multicast group used by Chromecast not being permitted by default.
Enable multicast group 220.127.116.11 on the wireless controller from the Web GUI with the following process:
Click Controller > Network > Topologies
Click the Topology Chromecast is connected to
Click Multicast filters tab
Click Multicast Bridging check box
Click IP group Radio button and add 18.104.22.168/32
The info is in the KB as well, pretty much what Rob said:Chromecast is not connecting or streaming on IdentiFi wireless
Here a link to the "The Extreme Networks Solution for Apple Bonjour Traffic Management"....
Because the setting is only enabled on this VLAN/topology the other VLAN/topology are not "affected".
