I just set up Bluecurve yesterday.  I already have a fairly sophisticated network so I put the bluecurve in bridge mode.  All wifi and wired devices connect just fine except Amazon echo devices.  They will not connect since connecting the bluecurve.  When I disabled bridge mode, I could hook the echo devices to the bluecurve but not to the mesh network.  

Any thoughts on why the bluecurve modem won't let my echo devices connect to the mesh network?
