Yosemite & Airport Express

I recently changed my home broadband router and now my Airport Express no longer works.

This is normal and expected, since the Express was programmed to use the settings provided by your old router. The old router is no longer there, and the Express cannot find it, so it is "lost" and does not know how to find its way.

You need to reset the AirPort Express back to factory default settings, so it will have the same settings that it did when it was new and you took it out of the box.

To do that.....

Power off the AirPort Express for a minute

Hold in the reset button first.....and keep holding it in for an additional 10 seconds while you simultaneously plug the power back into the Express

Release the reset button after the hold period and allow a full minute for the Express to restart to a slow, blinking amber light status

Now open AirPort Utility, click on the Other WiFi Devices button and click on AirPort Express

That will get the setup "wizard" started so that you can configure the Express with your new router.

Connect the Ethernet cable from the router to the AirPort Express and follow the prompts.

I read with interest this exchange since January as I have a similar problem. Now here the Airport Express unit is model A1084 and I cannot find a reset button. I feel stymied. How do I progress? (I use OS 10.10.4).

Incidentally the Airport Utility, which is now the new one from Yosemite, cannot work on the express. The old OS 10.6 version worked fine.

Apple dropped support of the older AirPort models over 3 years ago. If you need to administer the older AirPort, you will need to use.....or borrow for 10 minutes.....a Mac running Leopard (10.5.x) or Snow Leopard (10.6.x), or a PC that has AirPort Utility for Windows installed on the device.

Thanks a lot Bob. I did as you said and it now works.🙂

Happily I keep OS 10.6 on an external disk, and I also still have the old network.

So I reset the express from there and booted it up with the new network.

Really appreciated -- Karl
