One week after discovering a glitch between Apple iPhones and its Cisco-based campus wireless network, Duke University on July 20 finally got to the bottom of the problem that caused periodic outages of the Wi-Fi network.

Initial reports of the problem placed the blame for the outages squarely on Apple’s iPhones, which flooded the Cisco WAPs (Wireless Access Points) with thousands of address requests per second. However, in a statement released this afternoon, Cisco Systems admitted that the problem was caused by a Cisco glitch.

„Cisco has provided a fix that has been applied to Duke’s network and the problem has not occurred since,“ the statement read. Cisco did not describe what the source of the problem was. Late on June 20, Duke released a statement elaborating on the problem and how it was resolved.
