following would be the BEST option to begin addressing the issue?

A.
Reduce the power level of the AP on the network segment

B.
Implement MAC filtering on the AP of the affected segment

C.
Perform a site survey to see what has changed on the segment

D.
Change the WPA2 encryption key of the AP in the affected segment
