I had to turn off the new device notification.  My assumption was that it would notify me when a device joined my wireless network for the frist time.  This is useful (and a pretty typical setting) to make sure there are no rogue devices joining the network. 

Instead it notifies me each time a device joins, even if it has been on the network before, even if it has been assigned a profile.  Not sure how this is useful although I am sure that functionality matters to someone.  For me, it means that devices that go into sleep mode, like a Wii, ping me constantly each time they come back on.  

Is that the expected behavior of this setting?
