[ISSUE]: We have three legitimate wireless devices currently mapped. For the life of me, I can't remove the fourth device she added to the map.

ATTEMPT1:
I have renamed it to "REMOVE" and tagged it as "Possible Intruder Detected". I have DISABLED the wireless network connections to ALL computers, to access to force the "REMOVE FROM THE NETWORK MAP" option to display.

I select that option on the Network Map ... but when I reenable the wireless adaptor ... BINGO ... the device REAPPEARS as labeled "REMOVE".

ATTEMPT2:
I access the ADMIN panel of my router, and REMOVE the IP and MAC address from it using the "REVOKE" function. BANG, its gone as far as the router is concerned.

I then disable ALL wireless adaptors, select "REMOVE FROM THE NETWORK MAP". REBOOT both computers, reenable the wireless adaptor ... BINGO ... the device REAPPEARS as labeled "REMOVE".

WHAT??? I'm up for solutions short of reinstalling NM on ALL devices.
