my time capsule just flashes the orange color, WIFI or plugged into my MAC

A persistent, flashing amber light indicates that any of the several potential conditions may require your attention:

• The base station has not yet been configured because it is new, or the reset switch has been set.
• You have selected a security configuration that is not recommended.
• A new firmware update is available for the base station.
• One of several other conditions, such as a disconnected Ethernet cable or invalid IP address has been detected.

To find out why your base station's status LED is flashing amber:

• Open AirPort Utility
• Click on the AirPort base station
• Look for a Status setting in the small window that appears. Note: Status only appears if there is an issue or notification.
• Click on the small amber dot there and another window will open to explain what the "issue" might be.

If the TC has a flashing amber LED.. there will be info about the problem in the airport utility.

Please open your airport utility.. click on each of the TC in turn to open the summary .. and at the bottom it will show you the cause of the flashing. Plus give suggestions to fix it if you click it.

There are so many problems .. it can be as simple as firmware update or complicated as failed internet connections, disk failure etc.

Post a screenshot from each TC with explanation of how it is setup in the network and we can make further suggestions. We really cannot do anything without that info.
