Chromecast not streaming over wireless ...

[Kaitlyn_M_]

I'm using IdentiFi Wireless in my school district, how do I solve these problems:

- Chromecast is not streaming over wireless

- Chromecast utility is not able to locate the Chromecast device

Will this have any affect on any other wireless devices or will this only matter to the chromecast. I'm in the same situation and just want to make sure this won't mess up our laptops.

This can be caused by the UPNP Multicast group used by Chromecast not being permitted by default.

Resolution

Enable multicast group 239.255.255.250 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 239.255.255.250/32

Click Save
