I have a 4th gen 2GB Time Capsule connected to a Motorolla SB5101 modem for my wifi network at home. This has been a great setup for a year and a half and last week it suddenly stopped working. Whenever I check the status in Airport Utility I find "Ethernet Unplugged" blinking. I tried different ethernet cables and it didn't make a difference. Next, I called my internet provider and they reset my modem. It works fine when I plug in directly to my Macbook Pro Retina from the modem. Finally, I took the Time Capsule to the Apple Store. The guy reset it and setup a new test network. It worked flawlessly in the store. When I brought it home and reconnected everything I still had the same issue - "Ethernet Unplugged". My internet works and my time capsule worked in store but I can't get around this issue. I have restarted, reset, unplugged and replugged all the components numerous times. Additionally, the Router Mode is set to "DHCP and NAT". Am I missing another setting somewhere? Please help!
