Hello! I am new to this site so please be kind if this is something asked before. I recently bought a Time Capsule 2TB with the assurance that all I had to do was hook it up, plug it in and follow the screen. I plugged the ethernet cable from my modem into the port, plugged it in. The indicator light blinked green for a second and then flashed amber. Please help me understand what to do. Thank you!
