Use AirPort Utility. It is in your Utilities folder.
If you do not recall your Time Capsule's password, press its reset button for one full second but no more than that. Doing so will cause a "soft reset", disabling its password for two minutes, during which you can use AirPort Utility to configure a new password:
Thanks John but that is not the issue. Im just trying to change it. I went into Airport utility and changed it and everything (backup time machine) stopped working. So I changed it back now my iPad wont even connect to my wifi with the original password. It there a doc that tells how to change a password? Seems Im missing something... Never used to be this difficult as I remember.
I have no Idea why your iPad wont connect but after changing your password you will need to go into time machine to reselect the disk that your backups were stored in. After that there should be a popup asking for the password to the time capsule. You will then be able to enter the new password and after that it should work.
There are several passwords, and they are not necessarily identical:
- Your Time Capsule
- Your wireless network
- Your Time Capsule's disk
It's not clear which of them you want to change, but any of them can be changed using AirPort Utility.
If Time Machine stopped backing up, open Time Machine's Preferences and turn off Time Machine. Choose "Add or Remove Backup Disks", choose the disk, then Remove Disk. Confirm with the Stop Using This Disk button. Add it again. You will be prompted for the disk's password (not the Time Capsule's). Time Machine will turn itself back on, a backup will then commence, and your existing backups will not be affected.
The iPad is a separate issue, but it has a similar fix: go to Settings > Wi-Fi, select your network then "Forget this Network". Select the network again, provide its password, and verify you can connect.
Rather than try a number of different techniques to get AirPort Utility to find that base station, it will be easier and faster to simply "hard reset" it and reconfigure it again. Changing the wireless network network password will make it time-consuming and tedious to reconfigure it any other way.
If you are running OS X 10.9 "Mavericks" and yours is an original A108x model Express, do not hard reset it. Original, 802.11b/g - only base stations can no longer be configured with Mavericks. This includes the original A1084 and A1088 AirPort Express and all "round" AirPort Extreme Base Stations.
To "hard reset" an AirPort Base Station: make sure it's powered up, then press and hold its tiny reset button and keep it depressed for five to ten seconds, long enough for its LED to flash amber rapidly. Release the reset button. Then, the LED will glow amber steadily for about a minute. Then, it will flash amber, slowly, about once every second or two, waiting for you to configure it with AirPort Utility.
I am trying to reset my Time Machine password, but I can't figure out how to do it.
I am not using apple's Base station. I am instead using an external drive to backup my files. A detailed description of my problem is given here:
Any help you an give me will be much appreciated.
