If you're running OS X 10.6 and your Mac Airport won't turn on, try these quick steps:
1. Delete All Locations
2. Create a new location
3. Delete Automatic
4. Rename other location to Automatic
5. Delete Airport
6. Restart the computer
7. Re-add Airport
This is for OS X 10.6 since OS X 10.7 and later the wireless manager is called Wifi. The same process is still involved.
Method 2 – Deleting Plist
- Go to /Users/YourName/Library/Preferences.
- Drag this file to trash – com.apple.airportutility.plist.
- Empty Trash.
- Restart your computer.
If either of those don't work, try the following:
- Reset SMC – The system management controller is hardware on the motherboard that controls a few core functions.
- Reset PRAM – The Parameter RAM is a small amount of memory that your Mac uses to store certain settings and access them quickly. You can also reset the NVRAM, but the process is the same.
Airport Extreme Wireless Router
This article is about the Airport (WiFi) on your laptop, but if you found this article when trying to get Airport to work on your Apple Extreme Wireless Router, I present to you this blurb from the Apple StackExchange on the topic – “Airport extreme base station won't turn on.”
Try disconnecting all power supplies from the outlet/power source and the device. After 3 minutes hold the reset button down on the AEBS and then connect the power. Continue to hold the reset button down until the light on the front starts flashing amber fast or 5 seconds has elapsed (which ever happens first). If after the factory restore [not hard reset] that if the device doesn't turn on in a minute it's AppleCare time.
So if your Mac Airport won't turn on, which one of these processes worked for you?
