My new sub mini will not work with either of my beams with surrounds added or on their own, but if i remove the surrounds and set up as a stereo pair and add the sub it works fine :-(
very frustrating, have tried removing, and reinstalling, resetting and hard wiring but no change 
any help greatly Appreciated
It’s conceivable that the Mini has a fault with its 5GHz radio which prevents it talking to a Beam.
I suggest you bond the Mini with a speaker other than a Beam and submit a system diagnostic. Note the number and give Sonos Support a call.

Hi Ratty
connected the sub mini to one of my surrounds (play 3) after I removed them and it’s working fine. Sounds great. Ran a diagnostic then 16132009
This is my first time ever having any problems, do I just call Sonos after the weekend with my diagnostics reference?

Yes, that’s right. Support should be able to see from the diagnostic if there are any hardware issues with the Mini. If so, they’ll advise for replacement. If it looks okay hardware-wise they should be able to help get it connected.
The fact that surrounds work okay with the Beam, and that the Mini works okay with a separate speaker, eliminate the most obvious possible culprits.
Many thanks 
great little community :-)
if anyone else has experienced anything similar and have a fix it would be greatly appreciated 
but for now I’m waiting till Monday to call Sonos :-)
Did anyone find a solution for this? When I connect my Sub Mini to my 2xSL’s + beam it makes the sound shift between the TV and the Sonos system.
Actually, I discovered that it makes the connections to my other Sonos speakers through out the house unstable as well. :-/
When I disconnect the Sub mini everything seems to work just fine.. I tried using a cable as well. No luck.
