I am having trouble with my Time Capsule, backing up, and passwords. Earlier today, I was able to do a full initial backup from our iMac to the Time Capsule. The iMac had the password in memory, it accepted the password no problem. This evening, I am trying to start a new initial backup of my MacBook. On this machine, it didn't remember the password. I tried the one I had written down, but it was incorrect. So I went into Time Capsule setup and changed the device password to a new one. I entered the new password into Time Machine and it accepted it. But, when it went to start the backup, I got an error message window stating there was a problem with the username or password. I have tried the network access password and it is not accepted. Can anyone figure out what I'm doing wrong? Or if there is a problem with the Time Capsule? I also went into the settings and changed the network password. However, I haven't changed the password on my MacBook for accessing the network, and I am still able to connect. It's as if the Time Capsule is not accepting the changes, although it says it is.
