I have had a 2TB Time Capsule since November of 2013, set up in Bridge mode and it has worked great up until the last month or so. Now even though the WiFi portion continues to work fine it can't be located by the AirPort Utility either on my MacBook nor my phone and won't do TM backups unless I give it a reboot via the power cable. It will then work as expected for somewhere between 1 and 5 days before the same thing occurs again. My first clue there is a problem is that it stops showing up in Finder. Any ideas to cure it?
