Why can't I choose to set up Internet Sharing to computers using AirPort? I'm using OSX 10.9. I'm trying to set up Internet Sharing to connect my Android to my Mac directly over Wi-Fi. Every tutorial I've come across (including the one published by Apple) mentions checking a box for "AirPort" in a "To computers using" list. However, the option is simply not available on my machine:



I have a few related questions:


Why isn't the AirPort option available?
Is there anything I can do to make it available?
If there isn't, how can I work around it to finish setting up Internet Sharing so I can connect my Android and my Mac directly over Wi-Fi?
The option is not available because you have selected to share your connection from Wi-Fi.

You can't share your connection from Wi-Fi to Wi-Fi. Use an alternative method of obtaining a connection to the internet (e.g. Ethernet) so that the internet connection can be shared over Wi-Fi.
