Hellou!
I just bought Beam Gen2 and One SL, I have old Ikea symfonisk speaker. I love the sound of them but I cant pair them use surround voice.
Two compatible Sonos speakers are required to add a surround speaker. Make sure the products are turned on and connected to a WiFi network.
I have tried reboot all speakers, installed them many time, rebootted router and used ethernet cable to Beam. Nothing has helped,so far.
My router is ZTE MC801A.
Here is diagnostic number: 74666999.
Forgive me for my bad English :)
