Sonos and R550 unleashed

[beni_mahler]

I have recently replaced my R510 with an R550, I did connect the new R550 so the config could be transferred before I disconnected the R510.

Now my Sonos-Players need a couple of hours until all of them can be seen in the apps. Restarting Sonos players does not help. On some devices they are faster, on some slower. When the Sonos devices are unavailable in the app, i can see the IPs of some devices as "connected" in the unleashed system. If I restart a Sonos which is not connected it does not connected, it  does not connect after ther restart either. If the sonos are finally connected, after every restart of the AP the problem is back. 

If I reset the R510 and bring it back online, then switch the R550 off, everything works smooth. 

I am aware what Ruckus recommends https://support.ruckuswireless.com/articles/000006140

However this setting doesn't seem to be necessary in my case on the R510 and does not fix the problem on the R550

Hi Beni,

Could you check the WLAN configuration from the CLI when R550 is connected.

Check and make sure directed-multicast is disabled and directed-threshold is set to 0.

You can also check this information on AP's support logs.

I would check 2 things:

1. Physical level. R550 support new standards, and in some configuration older (802.11n) clients can't be connected to wif6 AP (802.11ax).   Check that most compatibel mode is configured. Take into account that R510 is 802.11ac AP, so it had not such settings. I don't have Unleashed R550 handy, so can't check how configuration looks (we don't use Unleashed at all, just vSZ). Disable any advanced limiting features. Try to ping speaker which connected to WiFi network -- if it isn't answeringe, than connection isn't completed. If you can ping it, but it still doesn't connect  to otherSonos devices, than problem is on network level -- most probably some protocols or ports are blocked.

2. Check that you don't have some type of client isolation or L2 filtering on. Sonos and similar devices use weird ways of communication, so disabling something may have unpredictable results. Disable ARP proxy and directed multicast, disable any filtering and rate limiting and try again.

We had no problems with R550 so far, but we don't use unleashed and we don't use Sonos, so it means nothing.

Thanks for your answers, I appreciate that you think about my issue. I have set the directed multicasting and the qos threshold according to this article now (you can see my config below): https://support.ruckuswireless.com/articles/000006140
In general, I have reset my APs after having this issue. I completely reconfigured them, doing only the minimal settings. (so ACLs, L2 filtering etc. is off)
I have set the two APs in two AP groups, so I can rapidly assign the SSID to one or the other AP. This should guarantee me that the settings are identical. My issue persists. After a reboot I can see the APs connected in the unleashed system, but I can not ping them (not from a PC and not from the unleashed system).When Troubleshooting one of the Sonos devices with the Troublesooting Tool under clients I can see that they finish the 4-Way Handshake but then do not request a DHCP address (which is fine if their lease is still valid). I am thinking about a remote wireshark radio capture of this SSID but I don't really know what to look for.
