Russell wants to know if he can use Time Capsule as a Wi-Fi extender. Leo says that Time Capsule is just an Airport Extreme with a hard drive built in. So it should be a simple matter of accessing the Wi-Fi part of the device. Leo says that when setting up the Time Capsule, set it up as a router to extend the existing Wi-Fi network. This will make the Time Capsule a bridge to extend the existing Wi-Fi signal, also called WDS (wireless distribution system). They key is to do it with all Apple products, as a third party router will cause issues. If he has a cable company router, put that in bridge mode and connect the Airport Extreme to it. Here's a great chart on how to get various routers to work with Apple products. He can also check PracticallyNetworked.com for more tips.
