My mac airport will not turn on

Make sure that you take a look at the security settings such as the wireless key and inspect the logs to see if there are any clues about potential issues. For example, if there are dozens of WiFi hotspots in the area where you live, you might be subject to wireless interference issues if someone else has configured their router to use the same wireless channel — try changing it from the default channel to something different.

You can also change the security settings for example to use WPA or WPA2 or remove them completely, to see if that makes a difference. If you can successfully connect another computer, iPhone or tablet for example, then it points to an issue with your Mac rather than the network kit or Internet connection.

Also, you should of course try connecting your Mac to another wireless network to see whether the problem persists. Follow the procedure below:. Locate the Command, Option, P and R keys. Press and hold down the Command , Option , P and R keys before the grey screen appears.
