Scotty,

My time machine disappeared. My time capsule shows up with Airport Utility, but it will not allow me to configure it as my time machine device. When I go to choose disk, nothing is there. Please help.

Here are several suggestions:

1. Be sure that first you of course on your own wireless network.
2. check system prefs/time machine, choose to change disk then reconnect to the airport disk once again.
3. try checking the status within airport utility. Sometimes you have to just cut your losses with Time Machine and start over again. You can erase the drive and start again. Not fun, but sometimes works.
4. It could be the hard drive inside the time capsule. Try connecting directly using ethernet.
5. try connecting from a second computer to eliminate the issue being the computer itself.
6. try reseting the time capsule by powering off (unpugging) then plugging back in
7. try turning off airport card then back on again.
