Hi, is it a common problem, that (RTSP)-Multicast-streams have a terrible performace over WiFi (the new WLAN-package), with wAP ax access-points? I have enabled "Multicast Enhance", but it has zero impact.
The multicast-sender is not in the same VLAN as the WLAN-clients, but if I connect to the WLAN-VLAN via cable, everything works pefectly. I route the multicast-traffic via PIM-SM, therefore I can rule out PIM as the problem.
Can someone verify that videostreaming via multicast works well over WLAN?
Multicast packets over WiFi are always transmitted using the "Basic rate", usually 1mbps in 2.4ghz and 6mbps for 5ghz
Ubiquiti used to have a "multicast enhancement" feature, where the AP/CPE's ignored the standard and forwarded multicast data using the "normal" signaling rates
Wifi and Multicast-video are basically incompatible, barring some hacks that are vendor/platform specific
... and so does Mikrotik: configuration.multicast-enhance with default setting disabled:
With the multicast-enhance feature enabled, an AP will convert every multicast-addressed IP or IPv6 packet into multiple unicast-addressed frames for each connected station.
This may improve link throughput and reliability since, unlike multicast frames, unicasts are acknowledged by stations and transmitted using a higher data rate.
