Multicast WLAN issues, chromecast and spotify

Multicast WLAN issues, chromecast and spotify

I have connectivity issues with multicast when I try to use chromecast and spotify. I have enabled multicast replication and configured per guide:
https://extremeportal.force.com/ExtrArticleDetail?an=000074801

Chromecast problem is with that cannot communicate it with android phone.
Spotify problem is that cannot control spotify at amplifier from laptop. Something to do with multicast.

My test setup is one 3805i AP and V2110 controler at other location. So traffic is bridged@AP. Version 09.21.02.0014. Traffic goes inside one AP. No problems if traffic goes between wired and wireless.

No problems if I use some bulk home AP. I have not filtered any traffic. All traffic should pass. Multicast bridging enabled with 0.0.0.0/0. Issue did exist also with couple older software releases.

Any clues where to check? This should be possible as this works with bulk no name AP, but not with identifi.

Hello Extreme Networks Community,

It sounds like you're experiencing issues with multicast traffic on your WLAN setup, particularly affecting Chromecast and Spotify. The Chromecast problem appears to be related to communication with your Android phone, while the Spotify issue involves controlling the amplifier from your laptop. Given your setup, with a 3805i AP and a V2110 controller bridging traffic at the AP, it seems the multicast traffic isn't being handled effectively when contained within a single AP, although it works fine between wired and wireless connections. To resolve these issues, you might want to explore more robust network configurations or firmware updates. Additionally, for a smoother Spotify experience, consider using the Spotify Unlimited Skips APK, which can offer enhanced functionality and control over your music playback.

Good Luck!!

Yes, I can provide screenshots. It is not all default as I have tried to debug why it does not work.

All devices are in same subnet.

Are the wireless devices on different subnets or on the same?

Could you please post a screenshot of the role that is used for this wireless client.

Hello Esa,



Do you have Wireless Replication also activated at the multicast configuration?



Like the help box it seems to be exactly your problem:

"Wireless replication" controls whether multicasts from wireless clients will be forwarded back to other wireless clients. Disabling wireless replication can save wireless bandwidth but some protocols (such as SpectraTalk's "Push to Talk" feature) won't work when wireless replication is disabled. When multicast bridging/forwarding is enabled while wireless replication is disabled multicasts to the address will only be forwarded from the wired network to wireless stations and from wireless stations to the wired network, not directly between wireless stations.



Regards,

Andre
