Hey there,

i use a MacBook Air 13" mid 2012 for work and at home. Wifi works perfectly fine at home but after I upgraded to El Capitan Beta, wifi at work (wpa 2 enterprise, "eduroam" (for those, familiar with it) did not. The MacBook was not able to connect properly and got stuck in an authentication process. After several days of regret, I "downgraded" back to Yosemite. At first I wanted to just reinstall OS X but noticed that any attempt to just reinstall brought me to a reinstallation of El Capitan. So I took the long way (clean install by formatting the drive, reinstalling Mountain Lion through internet recovery and finally upgrading Mountain Lion to Yosemite 10.10.4 (build 14E46) but the wifi issue remains the same. I tried deleting the SystemConfiguration folder and restarting but nothing seems to work. Any ideas out there? Thank you!

Have you tried connecting to other wifi networks to see if the problem occurs elsewhere? After all, the problem might be occurring within your employer's network systems. Talk to your colleagues to see if they're having problems too.

The majority of my collegues does not work with a Mac; the only collegue working with a Mac has no wifi issues but he did not upgrade to El Capitan Beta. I assume, upgrading changed my wifi settings which was not set back by reinstalling the operating system. But this is only the assumption of someone not that much into networking details
