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. Jeff
>>> 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.

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: Admin Mode: On Radio Mode: a/n Channel Width: Auto Guard Interval: Short ATPC: Enabled Max Tx Power: 24 dbm Min Tx Power: 8 dbm Auto Tx Power Ctrl Adj: 0 dbm Channel Plan: All Non-DFS-Channels Ant Selection: L/M/R Advanced: DTIM Period: 5 Beacon Period: 100 RTS/CTS Threshold: 2346 Frag.
