This is a reiteration of the comment I posted on MCPE-550 - Host not seen by clients (HTC Evo 3D):
We've also observed this issue on a B&N Nook HD+.
I just tested three devices (a Sprint Samsung Galaxy III running CyanogenMod 10.1.13RC, an ASUS Transformer Prime TF-201, and the Nook) on a single subnet, and the Nook was the only one that the others couldn't see as a host. All three ran fine as clients.

Indeed it is. But before we close this one out, let's update MCPE-550 to indicate the issue is not limited to the HTC Evo-3D.
Duplicate of MCPE-550 because they are talking exactly the same problem
