I don't suppose this update enables Time Machine to use an "AirDisk" connected to the Airport Extreme 802.11n base station...?

Probably along with many, many others who are suffering problems with the new Time Capsule, I looked forward to this update with anticipation. (For a summary of the massive number and seriousness of TC's problems, see Apple's Time Capsule Forum) No luck. Examples of TC's issues (which are not unique to me, despite a brand new Mac Pro, a Powerbook 17" and a G4 (867) all running Leopard and the new Airport Utility update, are:
1. Intermittent internet connections.
2. Weak signals across my small home; a $40 router does way better.
3. Printers plugged into the TC don't print.
4. Time Machine's backups go extremely slow--less than 4gb in 48 hours--and then stop altogether.
5. No sharing of files via TC among computers on my network.

Looking at the above, whether it's software or hardware or both, no one should be buying a TC until the bugs are swatted, and this software update did none of that.

This is the first time I've bought an Apple product (TC) that simply was put on sale before it was ready to work. (If there are solutions to the foregoing problems, which, in my view, encompass virtually everything one expected the TC to do seamlessly, they are not found in any manual, in any help file or even in any forum post. Perhaps they are scattered within the thousands of posts that now exist, but that means one cannot find them without making a career out of it. If the theme for Apple is to remain, "It just works", they need to pull the TC and fix it to the standards the company used to be famous for.)
