Yosemite: Time Capsule not found

Try adding Time Machine and Airport Utility to your firewall options/exceptions list

That did the trick for me as well. I don't remember having to do that in previous OSX's.

I perform this exception in the firewall, but, here, still the same issue. Didn't work.

Worked for me. Thanks!

What worked for me is allowing setup over WAN. I used the Airport App on my iPhone to change that setting and VOILA it showed up in the Airport Utility in Yosemite. Airport Utility > Select Time Capsule > Edit > Advanced > Allow setup over WAN.

Thanks Numenorean. That worked for me perfectly.

It didn't work for me. But the solution below worked.

Adding Airport Utility and Time Capsule in the Yosemite Firewall worked for me flawlessly. Thanks so much, MojoMatsu. This is what I did :

1. System Preferences / Security & Privacy / Firewall / Firewall Options / + button

2. Enter Airport Utility in the Search field / select Airport Utility / Add

3. Enter Time Machine in the Search field / select Time Machine / Add

4. OK

5. Unplug Time Capsule from the wall socket / wait 2 minutes / plug it in again

6. Airport Utility... and I could see the Time Capsule again 🙂

7. Time Machine... and I could see the Time Capsule again 🙂

Note :

- I did not have to add Airport Utility and Time Capsule in the previous MacOS versions. If Apple has added more security, it should display a proper message when a user is unable to find the Time Capsule : "Due to increased security, please add Airport Utility in the Firewall as an exception".

Thank you!!

Many days of frustration now solved.

Scratch that, still not working.

Device not found but my internet is still working, how does that figure?

THANK YOU MOJO MATSU & ARVIND AGARWALLA!! I downloaded & installed Yosemite a few days back & obviously had this problem. In addition to adding Airport Utility & Time Machine application to FIREWALL OPTIONS I think it's important to say 2 other obvious things. ONE IS TO MAKE SURE YOU ARE UNPLUGGING AIRPORT DEVICE AT THE WALL. SECOND IS TO DO A RESTART OF COMPUTER IF YOUR DEVICE STILL DOESN'T CONNECT. As previously said, both are obvious but when we're frustrated, I can forget the easiest options. AND I AGREE, APPLE SHOULD DEFINITELY DESIGNATE THE "FIX"

After almost 2 days and 4 hours, this was the solution that fixed it all!!!!! I can't thank you enough! I feel so accomplished!!!! Thank yOU!!!!!😀
