Oi! Im trying to configure my home network. I have a modem next to my mac in the office and my time capsule connected via Ethernet to the modem in my office. The time capsule/Airport extreme is in the basement and providing internet to the Apple TV/ ps3 and TiVo.... With wifi off, my mac cant see the time capsule/AirPort Extreme. Any ideas? I would like my AirPort Extreme to do double duty Acting as a extender and time capsule. Thanks.
