A new wireless network with four APs on the service set has just been installed in a local business’s building and is being tested for functionality and signal strength. The network technician connects to the wireless network without issue. As the technician moves throughout the building, the wireless connection moves between the first, second, and fourth APs without interruption. When moving to the third AP, however, the connection is lost. Which issue is the most likely cause of the connection problems with the third AP?
