I've tried searching for this so I apologize if it's already posted. I am setting up a Time Capsule and once I set up my main wireless network, I went in to set up the guest account. I set that up, and then clicked to apply the settings. Once the airport restarted, the Airport Utility no longer showed my Time Machine in the upper left hand corner, even though my Time Machine showed a green light. Both my main wireless network and my guest network were showing in the drop-down of my airport icon in upper right part of screen, but it will no longer connect to my main wireless network; however, it will connect to my guest network. ?????? WEIRD! When I go back into my Airport Utility, I get the message that the Utility could not find any base stations.....all the while, my light is green on my Time Machine and my guest network still works. HELLLLP!!!!!! I've reset the Time Machine and just set up the main network for now, but I need to figure out what I'm doing wrong in regards to the Guest Account so the software will still recognize my base station. Any help anyone could provide would be greatly appreciated.
