We have found that many of these are fixed by disabling IPv6 on the Airport

I'd be very glad to hear a cohesive theory (from the list, from Apple,
whoever) on why that might be.

We also see lots of problems with Macs being unable to obtain DHCP addresses
properly eventually ending up with a self-assigned IP address.
Attempts to engage Apple have not been helpful.

Subject: [WIRELESS-LAN] Apple and wireless connectivity issues?
Over the summer we upgraded our wireless infrastructure from all
autonomous Cisco access points to a managed Aruba wireless environment.
Since the start of the semester we have had issues come up that we have
been addressing, but we are now encountering something that we never
faced before - it seems more and more that the majority of new issues
we are dealing come from Apple laptops and mobile devices. We have
heard of some of the larger reported issues about Apple, such as the
DHCP issues with the original iPad iOS. We have also done some of our
own research on this and see Apple mentioned numerous times in regards
to wireless connectivity issues, but we don't know if we are seeing
this because this is what we are looking for or if because it is the
reality of the situation.
An example of this type of issue is that a student applied Apple
updates to her computer last Friday and then could not get an IP
address afterwards on our wireless network, though she could still use
her wireless router at home. Calling Apple about this resulted in them
telling us that if the computer can connect in one place but not
another that it is our problem and not an issue with the laptop, even
though many other Apple computers with the same version of the OS could
connect to our network.
We continue to troubleshoot and look to see if there is something that
is about our wireless network configuration that is causing problems.
However, we would like to see if others have experienced similar types
of issues on their campuses. Do you see a preponderance of wireless
issues over time relating to Apple products? If this has been the case
for you, were you successfully able to address issues with Apple? Did
you have to go back to your wireless vendor to fix these issues? Does
this sound like something unique to our experience here? We look
forward to hearing what others have experienced.
