I ran into an issue setting up Sonos Arc Sub and Surrounds. Sonos tech support mentioned that Ruckus access points convert multicast/broadcast traffic to unicast traffic, which disrupts expected Sonos behavior. Sonos requires multicast and broadcast traffic to be passed normally.
You should access your Access Point by SSH, using a tool like putty.
Then you should be able to configure the multicast:
ruckus> enable ruckus# config ruckus(config)# wlan MyWifiNetwork -> Change this for your network name ruckus(config-wlan)# no qos directed-multicast ruckus(config-wlan)# qos directed-threshold 0 ruckus(config-wlan)# exit The WLAN service 'MyWifiNetwork' has been updated and saved. Your changes have been saved. ruckus(config)# exit Your changes have been saved. ruckus# exit Exit ruckus CLI.
