Time capsule not showing but WIFI connection working

Hello

I have a Time Capsule 2gig that is used as the main WIFI router, connected to my normal router via Ethernet and a Airport Extreme used as extender. Up till today everything was working fine.

Now, when I open Airport Utility to view the connection, it shows me that the TC and AE are not registered anymore (device not found). But I can still access the Wifi and internet via the Networks I created, but not the backup.

I unplugged the TC and AE, replugged them, reset them and then the connection worked.

But now it is off again.

Does anyone have the same problem?

Regards

MacBook Pro (Retina, 13-inch, Late 2013), OS X Mavericks (10.9.4)

Unfortunately, this issue is not new and has been reported a number of time since OS X Mavericks.

The AirPort Utility relies on both the mDNS (aka, Bonjour) & the IPv6 IP protocols to find an AirPort base station.

When having difficulties accessing the AirPort thru the AirPort Utility, try the following, in order, checking for accessibility with the utility after each step:

Check the local connection. If you are trying to access the AirPort wirelessly, make sure that you are connected to its wireless network before running the AirPort Utility to administer it. If you are still unable to access it with the utility, temporarily connect your computer directly using an Ethernet cable to one of the base station's LAN ports.
Try accessing the base station by using the Utility's File > Configure Other… option. Then enter the LAN-side base station IP address (the default is: 10.0.1.1) and base station's administrator's password.
Verify that both the base station and your computer are configured for IPv6 Link-local only.
For a Mac: System Preferences > Network > Wi-Fi or Ethernet > Advanced > TCP/IP tab > Configure IPv6: Link-local only

For the AirPort base station:
Note: You may need to temporarily connect your Mac or PC directly to the base station by Ethernet to access it.
- From a Mac: AirPort Utility > Select the base station > Edit > Internet tab > Internet Options… > Configure IPv6: Link-local only
From an iOS device: AirPort Utility > Tap on the base station > Tap on Edit > Tap on Advanced > Tap on IPv6 > Change Configure IPv6 to: Link-local only > Tap on Done
Power cycle the base station. Remove the power adapter's plug from the power outlet, and then, wait 15 seconds before plugging it back in.
Perform a "factory default" reset on the base station.
Finally, if you are attempting to access the AirPort via an Ethernet connection, be sure that your Ethernet port is NOT configured for Jumbo Frames, i.e., using an MTU of 9000+.

I had also removed the Back to my Mac login, before seeing the previous posts, and it has been stable for over 30 minutes now.

Since we are all Apple product users, none of us would have any "technical details" on how exactly BtMM works.

The best I can offer is the following for BtMM's basic communications flow:

For a computer connected to the Internet via a router, BtMM "asks" the router for its configuration information. For a router, like your AirPort, that uses NAT-PMP, BtMM will ask the router to assign arbitrary public ports. In turn, the router will provide these port assignments (& the router's Public IP address) back to BtMM.
BtMM then sends this information to the iCloud account. In background iCloud updates a special set of DNS entries to be used by BtMM. These entries are then made available to all BtMM clients using your iCloud account. When a computer, with BtMM enabled, uses your iCloud credentials, it automatically retrieves a list of all other computers/routers that are registered with the same account. All these devices should then appear under the SHARED section of the Finder.
When attempting to connect to a remote computer (or router), BtMM creates a secure connection to that remote device using the information from the iCloud account.
Once the connection is established, the devices can then communicate with each other.

Thanks,

I also been having problem with my Apple ID connection before this happened. Either someone at Apple went live with a nice bug, or they are potentially being hacked or attacked

Thanks for the help!

After I set the IPv6 configuration to "Link-Local" I had to disable "Back to my Mac" for my TC and 2 AE's to solve the problem.

What I didn't have to do: Factory default reset the TC and AE'2 and disabling "Back to my Mac" on the Mac's.

Awesome. Been futsin' with this all day and finally stumbled upon this thread. Did an Airport Utility:File:Configure Other of 10.0.1.1 and erased Back to My Mac Apple ID ... and all appears good so far. I didn't notice when this started but I received a "new" Express yesterday and was trying to configure it but couldn't because there were no base stations to log in to. All the while wifi internet was working just peachy.

Disabling BTTM also worked for me.

I had the same thing happen to me tonight. Kept resetting it only to lose it again, till I realized that it was btmm that was breaking it.

The problem is, I really need to access my data and since I spent the time that I should have been working with the data on my disk trying to access it, now I'm going to need back to my mac tomorrow so I can do the work I didn't get done tonight.

You got me again Apple.

Losing my enthusiasm for Apple products.
