Unable to connect SONOS One SL

[NeedHelp1]

Hi, 

We are trying to connect our two SONOS ONE SL speakers to our wireless internet/fiber connection, but it seems as though some firewall (or similar) are blocking the configuration and thus the SONOS spearkers are unable to connect to the WiFi. 

Has someone had this issue before or does someone know what we can do to configure this connection correctly?

Tl;dr - make sure you're on the same VLAN and you have Wireless > Firewall and Traffic Shaping" Wireless clients accessing LAN" set to allow.

+1 for this. Sonos uses mDNS which doesn't cross VLAN boundaries.

To clarify, Bonjour forwarding can be used to have mDNS cross L3 boundaries

However from my experience, it can be a bit unreliable/slow.

The SSID will need to be in "bridged" mode as well.
