How can I share a Time Capsule connection?
Yes you can. Since the Time Capsule is an Airport Extreme with an internal hard drive it's relatively easy to convert it into a wireless to wired bridge assuming you already have it set to hook up to the wireless network.


Open up Airport Utility and start Manual Setup on your Time Capsule
Go to the Internet section
Under Internet Connection be sure Connection Sharing is set to Bridge Mode


If bridge mode is turned on it will share the connection and essentially act like a switch.
