Interference robustness
Wireless interference can come from a variety of sources, including other wireless networks, cordless phones, baby monitors, and wireless video distribution systems. When there is interference, some data packets may not reach their destination.These “lost” packets are automatically retransmitted, so no data is actually lost. Unless the need for resends is great enough to noticeably slow down data transfer, users are often unaware that there has been a problem. However, sometimes interference can be so severe that AirPort Extreme clients actually lose their wireless connection.
A feature called interference robustness is designed to maintain a wireless connection between an AirPort Extreme Base Station and an AirPort Extreme client in the face of severe wireless interference.This feature must be enabled on both the base station and the client computer.
Note that interference robustness provides a stronger connection between the client and base station, but may reduce the overall range of your wireless network.
