My network monitoring software identified open UpNp ports on my S4 as a vulnerability.  I found tp-link Tony's response which identified specific firmware updates by model to disable this feature.  S4 did not appear in the list of models.  Since the patches are model specific and I rely on the network I didn't want to walk down the list trying them till something worked or was totally broken.

Can you provide directions for turning the feature off (and on if it becomes too much of a problem)?  Also if Tech Support knows the S4 as some other model can you provide the alternate? I notice the S4 is conspicuous by its absence in most discussions.
