Hi there,
We are having a pretty shoddy experience with our 802.1x profile on our Macs, both Mavericks and Yosemite. Our setup:
AD accounts, RADIUS authentication. Extreme Networks gear.
10.9.4 and above (symptoms vary slightly from Mavericks to Yosemite)
Profile for Built-in-Wireless port, WPA2 Enterprise, Enterprise Mode: Loginwindow/System
PEAP, Autojoin, no proxy set
Trusted certificate included
We have a very inconsistent first log in success rate but even once past this we see very intermittent reconnection of wifi after laptop sleep. Close it for 10 seconds, bring it back up and the wifi sits as ticked but won't reconnect until manually done so in Network Preferences. Roaming also seems to be an issue with the profile, causing the same symptoms as we get from sleep.
We have investigated RADIUS logs and found nothing. However, I removed the profile from an affected machine yesterday and have had a flawless experience since.
Any ideas on this one? We are looking to upgrade our 10.9 fleet to 10.10 but are hesitant to do so until we can rectify this problem.
