Hey Guys, I think this problem started when I installed Sierra, but I cannot be 100% sure actually. So I got a 2TB Time Capsule a while ago because I wanted to be able to wirelessly backup my iMac and MacBook. I setup the whole thing and even use it as a router. All of this worked fine on both Macs until a couple of weeks ago (I believe it was when I updated both Macs to Sierra). Basically what is happening now is that I have to unplug and plug the Time Capsule back in every so often so Time Machine keeps making Backups. It always works fine for a couple of days but then just stops making Backups and connecting to the Time Capsule. This issue does not affect my Wi-Fi though, which mostly has been fine (though randomly dropping in the past couple of days). Let's say after 2 weeks I would look into Time Machine and see the last Backup was created a week ago, though there was no sign anything was wrong the past week. Then I click "Backup now" which will show "Looking for Backup disk..." forever until giving me a message that I should try backing up again when the server is available. I don't see a reason though why the server would NOT be available, since I'm connected to the internet through exactly that Time Capsule which is connected and working fine. I then try connecting to the Time Capsule in the Finder, which is there called "AirPort". It tries to connect but the Finder window will just stay empty and it will say "Not connected". Also, if I press the "Connect" Button it won't do much other then showing me some connection error after a while. What I do then is I unplug the Time Capsule, wait a second, plug it back in, wait for my Mac to reconnect to the Wi-Fi and it magically connects to the server. I can then run a Time Machine Backup without issues and even connect to the AirPort in the Finder. Anyone having similar problems or anybody knows a fix for this? I really would like my Backup Solution to work without having to restart it every couple of days Thanks!
