Error -6753 on Airport Express update

The AirPort Express lost communication with the Time Capsule during the update process and now things are out of sequence on the network.

Try powering down the entire network....every device.....order is not important

Wait a minute or two

Start the modem first, and let it run a few minutes by itself

Start the Time Capsule the same way

Start the Express the same way

Start each other device one at a time about a minute apart

Check to see if the AirPort Express is functioning normally. If yes, you can try the download again.

If no, you'll have to perform a Factory Default Reset on the Express and configure it again.

I had the same error, but after simply restarting the airport express, I found it had updated to 7.6.1 - problem solved (for me anyway...)

I had the same error. Simply restarting (unplugging) the Airport Express fixed the problem. It now reports 7.6.1 and everything is fine.

I had the exact same problem, restarted my Airport Express, and found 7.6.1 had been successfully installed.

Thanks mjthomp2 for the answer.

Thanks; this worked for me as well. My Express was blinking yellow until I rebooted, then I confirmed it was on 7.6.1.

Worked for me. Restarted and it reported 7.6.1.

Thanks.

I just went through all this today and thankfully got it all solved. I had an airport extreme with one airport express set up to widen the network area. I purchased another express to widen it again in a different area. The first setup has been working just fine for three years. When I went to add the second express I kept getting error -6753 when connecting. I read some of these threads and rest the EXtreme etc then I could access either express..

After calling in and finding a great support agent it turns out that when I connected the expresses with a LAN cable directly to my PC one at a time, resetting the expresses I was then able to access them under manual setup, which gave the error before, and get them added to extend the network. 10 minutes later they were both up and running again.

She is guessing it may be a firewall issue causing the error. Regardless, by using a LAN cable directly from the express to the PC it worked out great.

I hope this helps someone?! Cheers

TURN ON IPV6 on your PC wireless adapter! That's all!

Also I found that Norton Anti-virus will block the Airport Utility for Windows as well. Need to disable the firewall when making changes....

Hello,

Could you tell us what is the version of Windows and Norton you are running? Are you able to use the Airport Utility having the Norton Firewall disabled?

Let us know, we can help!

Thanks
