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?

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.
