I have around 20 students that have 2013 MBA devices running 10.8.4.  I have 
not seen a 2013 MBA device play nice on my 802.1x, PEAP, MS-CHAPv2 network.  
There are plenty of other MBA/MBP devices running 10.8.4 that do not exhibit 
the same behavior.  There are a few reports on the Apple Discussion Forums.
 
Here is one of them:
https://discussions.apple.com/thread/5234129?start=0&tstart=0
 
I do not own a MBA and can not test 10.8.5.  There is no mention of any 802.1x 
fixes in the release notes.  I have encouraged my building techs to find a 
student that will let us update their device (and not hold us liable).
 
For now, we have recommended all of our 2013 MBA students use our captive 
portal SSID and stay away from our straight 802.1x SSID.

I would be interested in what GTAC comes back with, if you wouldn't mind 
sending to the list.   We are having the exact same issue with MAC users.

Subject: [enterasys] Best AP/Radio config for high client/AP density?

I have an open GTAC case and am waiting for the standard Enterasys 
recommendations, but I'm curious what others have seen in the real world.  We 
have had reports of client connection issues at one school with a heavy Mac 
deployment in a group of adjacent classrooms.
Controller - C5110-2 firmware 8.31.03.0011 APs - 3610 - 1 per classroom Clients 
- MacAir OS X 10.8.4 (google search show other folks having WiFi issues if 
there is heavy channel interference), 33 per classroom.
SSIDs - 2 deployed, one hidden, both using NAC/RADIUS for authentication 
Topology is Bridge@AP for these authenticated clients

I've tried to push the config recommended from the help pages, but for some 
reason bulk AP radio configs are not sticking (I changed several of the ones 
listed below but looking at the current config they are not active).  I did 
enable DCS in active mode and will be onsite to monitor today - current radio 
configs are:

Radio 1:

11b:
Preamble: Long
11g:
Protection Mode: Auto
Protection Rate: 11 Mbps
Protection Type: CTS only
11n:
Protection Mode: Always
Protection Type: CTS only
40Mhz Channel Busy Threshold: 50

ADDBA Support: Disabled

I could go back and set them based on the 'High Throughput' settings list from 
the controller online help, but I don't want ot just randomly change settings 
without further logging or the recommendations from GTAC.

Thanks for any info!
