There have been nine instances since Friday where Duke's wireless local area network (WLAN) became jammed and inaccessible for 10 to 15 minutes, according to the News & Observer, a North Carolina newspaper. The iPhone is said to be the cause of the problem since it's programmed to constantly connect to the Internet through wireless access points. As a result, the iPhone could flood a wireless network and jam its traffic.
There are 100 to 150 iPhones registered on Duke's network, the newspaper reported. Duke uses Cisco's WLAN gear for its network infrastructure, but university officials believe the issues aren't connected to the Cisco equipment.
Other reports by Network World have said that as few as two iPhones at a time were able to flood up to 30 of Duke's wireless routers with IP address requests. The university's WLAN network stretches across three campuses -- West, East, and Central -- in Durham, N.C.
Duke's office of information technology could not be reached for comment.
There have been no other reports of this nature related to the iPhone and its built-in Wi-Fi capabilities.
