Upgraded to Yosemite this evening on my mid 2011 Mac mini and now I don't have wifi. The wifi menubar icon has an "x" on it and when I click on it, it says, "Wi-Fi: not configured." The only option is to Open Network Preferences.
When I open Network Prefs, there's no wifi option on the left, only ethernet, Thunderbolt, firewire and bluetooth. I try to add a wifi network via the "+" sign, but nothing gets added. My wifi network is working fine as my wife and kids' computers (on Mavericks) as well as all of our iOS devices connect to it fine as usual.
Luckily, my Mac mini is normally connected to the internet via ethernet cable, but I need to figure this wifi issue out.
When I go through whatever diagnostics, it sees my wifi network and allows me to enter my password, but then it won't connect. But, it only shows my wifi network via these diagnostics - not from the wifi dropdown on the menubar and not in Network Prefs.
Any thoughts?
Thanks.

perhaps shut down the wifi network and re-boot.
it might then "find" your mac mini/router.
fingers crossed for luck.
ymmv
be well.

Thanks, but I tried that already.
Also forgot to mention that when I upgraded to Yosemite, my wifi was OFF (b/c I normally connect to the internet via ethernet).

1. Try rebooting;
2. Try a safe-boot-and-reboot (Hold down the shift key after boot-chime, then click the restart button when you get to the login screen and don't hold down the shift key on the second startup.);
3. Try zapping PRAM. (Hold down Command+Option+P+R immediately after rebooting and continue to hold down those keys through 4 boot chimes.);
4. If all else fails, remove the /Library/Preferences/SystemConfiguration folder and reboot. This will clear all of your network settings, so it's last resort for frequent travelers with a laptop that has a lot of WiFi and VPN settings to worry about, but for a desktop Mac is probably not too onerous.

It should not happen. Safe boot or re-install Yosemite.

Definitely can and no surprise it has spilled over.
There have been quite a few WiFi issues in Yosemite (easy search/find) during the Developer build that has affected various installs for whatever reasons. I have a machine still has issues.

please define "remove".
does it mean trash?
does it mean simply moving out of the library folder?
will it automatically rebuild on re-boot?
will any other network settings be affected or will this re-set all network settings?
thanks in advance to any and all who care to share.
be well.

I took it to mean "trash", but I didn't empty the trash until I rebooted and saw that my wifi was back. I also checked that my ethernet was still working.
I then emptied the trash.
However, I didn't go back to that folder location to see what was recreated inside the folder.
I'm at work now so can't check.
