I've spent hours on the phone with Tier 1 and Tier 2 engineers form Sonos tech support and do not have a resolution. I'll be disappointed to return the Sonos system, but it's useless to me without a subwoofer. I figured I'd give this board a shot in hopes that someone out there knows a fix. I connected the Play Bar no problem. But the sub will not connect. If I plug I directly into my wireless router it connects, but once I unplug it and go back to wifi, it won't pair. Sonos can find it, and when I push the button to connect it recieves the signal, but it WILL NOT pair with the play bar. Again, I've spent hours on the phone with tech support and they are at a loss, so any "easy" fixes probably aren't right. I need to think outside the box here!
