Apartment Provided Internet (FIber) with Ruckus Access Point and Sonos

Hello,

I just moved into an apartment that provides internet access via a wireless Ruckus Access Point. It is ceiling mounted. I have numerous Sonos speakers. Each one is configured and working fine. However, when I try to add Sub and/or Surround speakers to the sound bar (Sonos Arc) it will not work. I did some google searches and I believe that the access point needs to be configured differently and to turn off directed multicast (or something like this). I just would like to speak with someone who manages this configuration for my service. There is NOTHING wrong with my speakers. They work and have worked with sub/surrounds for years until I just moved to this apartment. In the past, I provided my own equipment, but do not have that option. Thank you.
