IPhones Flooding Wireless LAN At Duke

coondoggie sends us to a Network World story, as is his wont, about network problems at Duke University in Durham, N.C. that seem to be related to the iPhone. "The Wi-Fi connection on Apple's recently released iPhone seems to be the source of a big headache for network administrators at Duke. The built-in 802.11b/g adapters on several iPhones periodically flood sections of the school's wireless LAN with MAC address requests, temporarily knocking out anywhere from a dozen to 30 wireless access points at a time. Campus network staff are talking with Cisco, the main WLAN provider, and have opened a help-desk ticket with Apple. But so far, the precise cause of the problem remains unknown. 'Because of the time of year for us, it's not a severe problem,' says Kevin Miller, assistant director, communications infrastructure, with Duke's Office of Information Technology. 'But from late August through May, our wireless net is critical. My concern is how many students will be coming back in August with iPhones? It's a pretty big annoyance, right now, with 20-30 access points signaling they're down, and then coming back up a few minutes later. But in late August, this would be devastating.'" So far, the communication with Apple has been "one-way."

    That's preposterous. Summer is when teachers return to their coffins to rest. Who would the students learn from?

    No wonder there is no answer... Apple people weren't able to receive any network package with all those iPhones around.

      Communication with Apple is always "one way". Or the highway.

    Isn't the term "zombie" a little bit redundant?

    No wireless hardware requests a MAC address.

    But the iPhone is from Apple, of course it would ask for a Mac address! Heck, they should be glad it didn't ask for a Mac-II address, things would be twice as bad!
    (You can do the math for a Mac-IIcx :)

    But that's exactly the problem. The iPhone handshakes with a "How are you gentlemen." and asks for a MAC address, at which point the WLAN's response is "What you say !!" and it goes downhill from there...

    Well, obviously the Airport access points will give the iPhones MAC addresses as the summary suggests... unlike most brands of access points. =)

    I'd love to hear that help desk phone call at Apple:

    Student: I'm at Duke and my iPhone's wifi just stopped working.
    Apple rep: I'm sorry sir, but Apples just work
    Student: Yeah, well mine isn't just working right now!
    Apple rep: Sir, do you BELIEVE in the power of Steve?
    Student: The what?
    Apple Rep: Sir, maybe if you had more faith in Steve, you wouldn't be having problems...
    Student: Look, I just want my damn phone to work.
    Apple Rep: Then I think you need to attend our Apple Reaffirmation Camp
    Student: Will it help get my wifi signal back?
    Apple Rep: No, but it will help you get your FAITH back, and stop questioning the infallability of Apple products
    Student: Um, okay. Anything to get my smug sense of superiority back.
