TC no longer a part of my network but my wifi network is still working, mostly. What has happened?

I've been having the same issue over the last few days.

I've tried soft, hard and factory resets, but the TC becomes 'lost' after just a few minutes, even though it can be pinged.

Internal disk can't be mounted, and attached USB printer is no longer available.

Running El Capitan 10.11.6 on Mac Pro, and MacBook Pro. Sky Q router. Firmware on TC is 7.7.7

Having the same issue, it started today (13 Aug). Tried a number hard resets, the TC shows up for a few minutes and I recover the previous settings. Then after a few minutes it can no longer be seen in Airport Utility although the wi-fi is working. Can't see the 'Data' HDD so no Time Machine backups. I am also using El Capitan 10.11.6.

I am experiencing the same issue, only as of the last day or so. Reading this thread provides some relief that my network has not been hacked. Like most I am running the latest OS version 7.7.7

I can browse the TC data share from my iPad, iPhone and Apple TV, using streaming apps such as File Explorer and VLC. However, I am unable to see the TC from my OS X devices.

I have tried connecting using both wifi and ethernet cable, makes no difference. I have also performed the 'hard reset'. This fixes the problem for around 5 minutes, then once the password is configured etc, it drops off the grid again.

To manage the device is technically still possible, using the Airport Utility app. I select File then configure other, enter the password and I can then manipulate the settings.

I can only assume that this is a bug and there will be a fix on the way shortly.

Same problem happened in my TC.

Remove any iCloud ID from "Back to My Mac" in TC, then TC will come bake and you can connect to TC drive and TC setup again.

I think this problem come with the Firmware 7.7.7.

DaggMask, thank you very much for posting. I removed the AppleID from the 'back to Mac' setting, restarted the TC and I can now manage the device just like before. 🙂

Thank you very much. Followed your advice and it looks like it has done the trick. 🙂

What I do not understand is that, if this is indeed linked to the v7.7.7 OS why has it just begun to be an issue now, given that it has been released for a whilst now. The issue only started this weekend. When you re-enter the 'back to mac' settings and restart the problem returns.

Hoping for an update to fix this once and for all shortly.

The issue is caused by Back to my Mac.

Disable Back to my Mac in the Extreme / TM and restart the device. You can do that by selecting Configure another device in the tool and enter the right IP/password to the device. Then remove your iCloud ID and restart. Worked for me and others.

Removed iCloud ID from TC and everything is is back to normal. Thanks for the help.
