Airport Express Model A1301

A1301 is an AirPort Extreme......not an AirPort Express. This model was produced between March 2009 and October 2009, so it would be aboutt 6 years old.....and the average useful life of a router designed for home use is about 5 years.

Are you still using OS X (10.5.8) as your profile indicates? If not, what operating system do you have currently installed on your Mac?

As a last resort, try resetting the AirPort Extreme back to its factory default settings and then set it up again to see if that might give the AirPort Extreme a bit more time.

To reset back to factory defaults......

Power off the AirPort Extreme by pulling the power cord from the back of the device

Wait a minute

Hold in the reset button first, and keep holding it in for another 7-8 seconds while you simultaneously plug the power cord back into the AirPort Extreme

Release the reset button, and allow a full minute for the AirPort Extreme to restart to a slow, blinking amber light status

Set up the AirPort Extreme again. If problems persist, it is time for a new router.
