It is possible to restore your AirPort express to factory settings following simple steps. Here is the process that you need to follow.
- Unplug your Airport express from the power source
- Get a paper clip and bend its end down until the paper clip is straightened.
- On the AirPort express, next to the audio jag, you will see a small button called reset button. Press this button using the paper clip, or alternatively, you can use a pencil or a pen.
- While the button is still down, insert the AirPort Express back to the power source and release the button as soon as the amber light flashes.
- Connect the device to power source and wait until the start up process is completed
- Press and hold the reset button down using a pencil or pen. Hold it down for one second and then release it.
- The LED light will start flashing amber, showing that the AirPort Express is in soft reset mode.
- Go to AirPort menu bar item and choose the network that was created by the device
- Go to Applications, then Utilities and open AirPort Utility
- Select the base station and then click Edit. Then change the password or settings if needed.
- Click Update and Continue as required. Close the AirPort Utility.
- Press and hold the reset button using a paper clip or pencil until the LED status light starts to flash amber, which will probably happen after 5 seconds.
- Once you release the button, the device will reset. Allow some time (about a minute) for the base station to finish the restarting process.
- Launch AirPort Utility via Applications and then go to Utilities.
- From the other WiFi devices, choose the base station and then click Edit.
- Select the Other Options button. Then select “Restore previous settings” and press Next until you see the last window. AirPort Utility will let you know that the Setup is completed.
- Press Done and close AirPort Utility.
