Had my time capsule for a few days now and have had no luck setting it up. I have installed the cd and want to add it to an existing network. I have gone to the airport utility in an attempt to set it up as said in the instructions but it does not find the capsule. It is place right next the computer so its not a problem with the range. The amber light is flashing on the front which i know what it means but cant seem to work it out. Any ideas?
