Ben Miller of Sniff WiFi comments:

I defend Apple a lot.  When Network World wrongly accused  the  original iPhone of flooding Duke University’s network, I defended Apple.  (It was later found to be a Cisco problem.)  When a health care provider I was doing some work for blamed SIP-enabled iPhones for a VoIP problem, I eventually found out that  the  APs were to blame.  (The  APs were failing to respond to WiFi frames tagged as “Background” QoS.)  Time and time networking folks blame device makers like Apple, and time and time again  the  problem ends up being  the  network.

There are times, however, when it really is Apple’s fault.  When  the  network is operating just fine.  This is one of those times.  The  problem is that I just don’t know why.

An interesting issue that Ben has uncovered with Apple devices and wireless performance. With so many iDevices on our networks now, how will Apple respond?
