Not sure if I can help but.
My understanding is, that wireless networks work in 2 modes, one where
each node can see each other and the other is where they can't see each
other. But I believe the ap should have a record of each currently
connected node, maybe you machine is disassociating itself from the
wireless network ?
The AP should be able to see it at all times
