Yesterday I upgraded my older generation time capsule to the latest version. I plugged in my cable modem connection into the input, and ethernet cable (and thunderbolt adapter) out to my macbook air, and I was briefly able to get a wired connection working, but no wireless. I tried rebooting my modem and router but was then unable to get either wired or wireless connection working again. Airport utility on my 2013 macbook air initially located the time capsule, but after the reboot the time capsule kept blinking amber and airport utility could no longer locate the time capsule. Since then I've tried rebooting again, soft reset, and factory default reset. No luck. I've confirmed that connecting directly to my cable modem works fine, and my old time capsule does too. Is my new time capsule defective or is there something else I can try?
