I have attempted a hard reset by holding in the reset button.
A Hard Reset is performed with an AirPort router by powering it on for a minute or two, then holding in the reset button for 8-10 seconds and releasing. The AirPort will restart, first with a solid amber light, then it will turn to slow, blinking amber.
It will stay slow, blinking amber until the device has new network settings, at which time it will turn solid green. The AirPort will not blink green continuously.....unless it is defective.
I attempted a factory reset by unplugging, holding the reset button, and plugging back in while continuing to hold the reset button.
That would be correct, as long as you held the reset button in 8-10 seconds before releasing. As mentioned above, the AirPort will restart, first with solid amber light, then turn to slow, blinking amber after about 30 seconds.
After a Factory Default Reset, the AirPort will display a slow, blinking amber light until the device has new network settings, at which time it will turn solid green. The AirPort will not blink green continuously.....unless it is defective.
If you need some help setting up the AirPort Express, we need to know which model you have. Please locate the model number on the side of the Express. It starts with an "A" followed by four numbers.
Next, we need to know what version of AirPort Utility that you are using. That is the same application that you used to set up the Time Capsule.
