Can someone explain to me the benefit of a Time Capsule that has Gigabit LAN where my BellSouth modem does not support Gigabit? My modem recently crapped out on me as did my Netgear Router (okay what's the third thing here)? I got a replacement Motorola modem from BS and a new Netgear WNR3500 with Gigabit LAN. I found out later that my modem doesn't have Gigabit functionality.
