I have spent the last 8 hours trying to configure Time Capsule. I have a Windows PC, a MacPro and a brand new MBP. The Windows PC is connected to TC via Ethernet, so it works fine. The MacPro is connected wirelessly and IT works fine. The MacBookPro is visible "sometimes", but 99% of the time it constantly requests the password [which hasn't changed], and even when provided it says its "wrong". Plug it in via ethernet... it seems to work. During all of this I ended up with an aborted TimeMachine backup... so I figured I'd erase the disk and start over.... You have to use AirPort Utilty to do this, not Disk Utility. Anyways.... I told it to do a "quick erase"..... and its been over an HOUR [and the screen says NOT to interrupt it!]. I'm about at wits end.... I just spent $3000 and am not a happy camper. Anyone have any ideas?????
