Yes, we have discovered that there is a small issue with the SoundBridge that causes it to not work reliably with some small percentage of wired routers and switches. The one driving your wall-plug net drops must be one of these.
The reason it works with the hub is that the isolates the SoundBrdige from the switch in your home-run that we are apparently not compatible with. You can:
- Contact firstname.lastname@example.org
and we will swap the SoundBridges out with ones that have this problem fixed
- Leave your hub in, or move the hub to your home-run, and have it drive the two drops going to soundbridges
- replace the switch in your home run with a different brand (note that there is nothing "wrong" with your switch).
Sorry for the inconvenience.
