In the Airport utility on the newer Macintosh wireless machines, there is an optional setting "Use Interference Robustness". Searching Apple's web site turns up little of value on what's actually happening, and Googling turns up a lot of theories but little concrete info on what this setting is doing. Among the theories: - This only has value when talking to an Airport base station also set up for the same setting - It lowers usable range - It lowers throughput but makes for a more reliable connection - It changes receiver sensitivity - It increase throughput - Etc, etc, etc So far on our Cisco LWAPP network, I'm having a hard time drawing any conclusions- indicating that perhaps it does only have validity when used with an Airport base station... Would be nice to know exactly what is supposedly being manipulated by this setting. Here's one of the more detailed theories: http://nslog.com/2006/09/23/airports_interference_robustness_and_transfe r_speed (bottom entry)- but there's a lot of other guesses as well floating around. Anybody actually have a handle on this one? Lee H. Badman Wireless/Network Engineer Information Technology and Services Syracuse University 315 443-3003
