MacWorld is reporting that unlike earlier reports where the iPhone was blamed for a bad WiFi experience on the Duke University campus, the iPhone had nothing to do with the problem. it's really a Cisco Wireless Access Point that's to blame.

Supposedly, the Apple iPhone was responsible for flooding Duke's network with ARP (Address Resolution Protocol) packets. This makes it difficult for any device communicating on a network-WiFi or otherwise-to communicate with other hosts on the network. This flood supposedly cause the Cisco Access Points to become non-responsive.

Friday's statement on the Duke University website exonerated the Apple iPhone and laid the blame squarely on bad software on the Cisco Access Point. Quoting from the statement:

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. We are working diligently to fully characterize the issue and will have additional information as soon as possible. Earlier reports that this was a problem with the iPhone in particular have proved to be inaccurate.

Looks like the iPhone is safe to use on your WiFi network again. But I think the iPhone fanboys didn't have any doubt. Did you? Share in the comments.
