By the kindness of my coworker's heart, she got me an early Christmas present in the form of a 2TB Time Capsule. Believe me, I was like this the whole day yesterday. Anyways, initial set-up was a breeze. I set the TC up to be just my external drive, since we already had a 802.11n router. So with that, I set up my Time Machine and it went easily. Then I hit the initial backup, mind you, it was wirelessly. So with how slow it was, I decided to search on here for how to do it using an ethernet cable and I came across this thread http://forums.macrumors.com/showthread.php?p=8474046#post8474046 and on there post #6, proved to be the most helpful. Set it up and blammo, my initial backup via ethernet went fast. Then came the trouble. I wanted to set it back up to wireless. I followed the poster's instructions and followed them, with the ethernet cable still attached as advised. But then now, I'm getting the message that "The settings for your Airport device have been updated successfully, but there was a problem re-joining the wireless network or finding the Airport wireless device." And then Airport Utility can't find it, so I'll reset the TC to factory settings and AU will find my TC, but I'll get the same message. Any help will be appreciated.
