    iPhone not to blame for university Wi-Fi problems

Network problems at Duke University that had been blamed on Apple's smartphone and its Wi-Fi implementation turn out to be down to a bug in the Cisco-based university network.

Having initially taken the blame for grinding a leading university's wireless network to a halt, the iPhone has been found innocent, easing concerns over the way the phone interacts with Wi-Fi hotspots.

North Carolina's Duke University had reported that the high numbers of iPhone users trying to access campus hotspots had frozen parts of the network for up to 10 minutes at a time.

But the university's chief information officer later revealed that the fault lay not with the growing numbers of iPhone handsets on campus, but with networking equipment elsewhere.

"The reality is that a particular set of conditions made the Duke wireless network experience some minor and temporary disruptions in service," Tracy Futhey explained. "Those conditions involve our deployment of a very large Cisco-based wireless network that supports multiple network protocols.

"Cisco worked closely with Duke and Apple to identify the source of this problem, which was caused by a Cisco-based network issue. Cisco has provided a fix that has been applied to Duke's network and there have been no recurrences of the problem since."
