Are you requiring DHCP (there's a checkbox) on your SSIDs? This might
add to the frustration with Mac clients. Mac clients have trouble re
associating after going to sleep here which has something to do with
the RFC the Mac uses for DHCP being newer. We stopped requiring DHCP
on our .1x SSIDs to try to mitigate this. A combination of that, the
client driver update that came out a couple months ago, and the
following tidbit I pasted in below that we managed to get from an
engineer at Apple seemed to make things better here. One thing I wish
they would fix is to give us a control on whether the Mac uses .11a or
b/g. My personal Macbook Pro still has issues when it decides to
associate to the .11a radio, but on days when it goes .11g it works
perfectly. The guy at Apple told me if enough folks complained about
this he could escalate the issue. Should I invite him to join this
list and invite us all to petition him?
This behavior can be changed/disabled and, in fact, Leopard has a
special case workaround for tmobile Hot Spots to deal with just this
type of scenario.
If you look at this file:
/System/Library/SystemConfiguration/IPConfiguration.bundle/Contents/
Resources/IPConfiguration.xml
you will see two parameters:
RouterARPEnabled
RouterARPExcludedSSIDs
The former, RouterARPEnabled, can be changed to <false/> using plist
editing tool (sadly, defaults will not work for this) such as
PlistBuddy or Property List Editor. This will disable this behavior
entirely.
Alternatively, you can leave RouterARPEnabled set to true and simply
disable this behavior for specific SSIDs, which you do by adding an
entry under the RouterARPExcludedSSIDs.

Is anyone out there a Cisco controller shop that's seeing lots of
troubles with Apple products? We're transitioning (still) to an
entirely
controller-based infrastructure so we have a mix of buildings that are
running on those and some that are still IOS-based APs.
Lately it seems a lot of tickets are coming into our help desk from
Apple users that are in the vein of "it used to work but now it
doesn't"
but only in buildings running on the controllers. I'm left
scratching my
head as to why since I cannot reproduce the problem on my. A while
back
there was a thread on this list about tweaking EAP timers and I've
made
those changes to our controllers but to no avail. Anyone have any
insight into this?
Thanks,
