Q: Mac mini (2014) WiFi Connection Problems
Hello,
my new Mac mini (2014) with OS X Yosemite arrived today. Problem: It won't connect to my WLAN. My network doesn't even show up in the list of available WLAN's. If I try to connect directly to my WLAN (entering name and password), OS X says "network not found". But my old Mac mini (2012) and my MacBook Pro (2010) connect both to my WLAN without any problems!
I already tried to delete some preference files, installed OS X 10.10.1, did a PRAM reset and deleted the WLAN connection and added it again - it didn't help. The brand new Mac mini won't connect to my WLAN...
This can't be true... I buy a new computer and one of the most important feature doesn't work.
Is there anything I can do? Thanks for _any_ advises and tips!

My problem is solved!
The external USB 3 SSD was the cause of the problem. I moved it away from the Mac mini and used a different USB port (that one besides Thunderbolt) - and WiFi works fine now!
The problem is that USB 3 can interrupt/disturbing WiFi connections.
Background:
"Some USB 3 devices, hard drives in particular, can generate radio frequency interference that can cause Wi-Fi and Bluetooth devices operating in the 2.4GHz band to have issues communicating with your computer."

Please keep this in mind when connecting USB 3 devices to your Mac. Hopefully this post will help others.
