Im new to the OS X mini thing (about 2 hours new to be exact

I probably got one of the last mini 9s, Dell discontinued it like the next day after i bought mine :/ but that's another thing...
Anyway forgive me if someone has already mentioned this but could the problem for *some people* have something to do with installing OS X from another Mac, such as with the "runcore USB" method? Depending on which Mac you boot from, different default network adapters get created in the Network System Preferences. I had a similar problem with WIFI not being on when I booted, and for me the "Airport" item in Network preferences didn't work at all, it was using "Ethernet 2" as my wireless adapter, while Airport did nothing. Well, the Mac I used to install OS X onto the Runcore
ssd was a Mac Pro- which has 2 ethernet adapters but no Airport card (in mine).
After I removed all of the "Extra" network adapters from the Network pane and Applied changes, then i added back the Airport manually. From then on it started "acting" like Airport in a Macbook (remembering to stay on after boot, the menu bar icon worked for adding networks, etc). It's as if the setup with the bunch of network adapters that existed on the Mac Pro but not the Mini 9 was confusing it...
In case that helps anyone else who has a mini 9 boot drive that was formerly used to boot an Apple Mac.
