Q: WiFi with Exclamation mark after upgraded to Mountain Lion
The light is green, under network, and the connection works even though I have an exclamation mark on the wifi sign. Airplay doesn't work, on my Apple TV. Already tried to switch everything off/on but nothing changed. How can I fix it?
MacBook Pro with Retina display, OS X Mountain Lion, I love it!

Backup these 2 files:
/Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
/Library/Preferences/SystemConfiguration/preferences.plist
Then delete these 2 files and reboot. If you upload these 2 files someplace I can take a look if something was wrong in there.
