How can I make my wifi invisible to others

i would like to know how to make my wifi connection invisible to others

This is not really possible, since there are any number of free utilities on the Internet that will reveal a "hidden" network in seconds. Anyone who wants to see your network will be able to do so very quickly and easily.

iOS devices like the iPhone and iPad often have difficulty connecting to a "hidden" network as well.

If you still want to do this......

Open Finder > Applications > Utilities > AirPort Utility

Click on the Time Capsule icon, then click Edit in the smaller window that appears

Click the Wireless tab at the top of the next page

Click the Wireless Options button near the bottom of the page

Enter a check mark in the box next to Create hidden network

Click Save

Click Update at the lower right of the window and allow a minute for the Time Capsule to restart

Please note, invisible wifi is not and never was part of the specs for wireless networking.. it was a rather silly invention of the router manufacturers in the early days of wireless when WEP was the best security around.

The reason it causes trouble is that your wifi then does not comply to IEEE standard.

And it offers no improvement in security.. please stick to WPA2 personal with a decent password for security.. that is the one and only method.
