My 3TB Airport Time capsule has two major issues. Since September 9, the time machine feature on my macbook pro retina (late 2013) has not been able to find drive in my time capsule and cannot backup to it. Also, when I use the time capsule as a wifi router, I have a weak connection. The connection is stable enough for a while, but my macbook eventually loses the signal completely. Additionally, I also notice the airplay display icon in my menubar will disappear and reappear every few minutes. I have tried restarting my macbook and my time capsule, but the issues persist. I also did a hard reset of the time capsule and I still have those same problems. I should mention that September 9 is also the same time I upgraded from Yosemite to El Capitan’s GM release. Would my problems be related to my OS upgrade or could it be a hardware issue?
