Multicast groups: either
239.255.255.249:9001 - general Sooloos discovery messages
or
239.255.250.250:9131 - AMX beacon message

239.255.255.248:9002 also provides application status logging

If you have a network that treats multicast as multicast rather than broadcast, then these will be invisible to you unless you join the multicast group. Also, many wifi access points filter these messages to the point that specific messages, such as AMX beacon messages, may only be received several minutes apart - hence the appearance of no connection.

If you monitor for status logging group, you should see loads of log messages as logging over network is quite prolific on Sooloos.

The general Sooloos discovery messages come round about 15-20 seconds apart, until they are being filtered by wireless access points but one device may send several types of discovery messages. i.e. a MC200 will send core, store, audio endpoint, broker messages so you should see something on group 249 every few seconds.

These are in conjunction with UDP unicast messages for audio and TCP messages for handshaking.
