Thanks. I tried that but I got as far as step g. Also, I was able to connect to my Time Machine hard drive under Network in the Finder. It did not show up as Shared in the sidebar. Is that perhaps that is the issue? I thought since I could still connect to the hard drive (as shown below), it would still work. Note that I followed all other steps as outlined.

If the drive does not show in the sidebar, open it in the Finder, then drag the little disk icon in the title bar to the sidebar. Then, see if it shows up in Time Machine. Dragging the icon in the title bar is a little tricky in that you must click and hold, then drag after about a second.

I finally got around to trying your suggestion. It partially worked...I was able to start the backup (i.e. it recognized the external HD on my iMac), but it got stuck at "preparing for backup". It just continued to spin and spin until I got some message that it wasn't able to back up. And, I did see the external HD was being accessed since the lights on it started blinking.
Anyway, close but not quite. I appreciate the help though. I'll just have to remember to connect the hard drive direct to the laptop from time to time and backup manually.

See #C2 in Time Machine - Troubleshooting. It will show you how to locate the message(s) that describe the problem, then help you fix it. If that doesn't help, post back with details, including all the messages, your setup, what you've done, and the results.

Well, I'd like to, but it requires me setting everything up again. I've decided not to do the backup via wi-fi. My wife's laptop does not have any critical documents on it that she can't replace, and with iCloud, all her email and contacts are backed up...so that's most of the battle.
I'll stick to physically plugging in the external hard drive and doing the backup from there.
Thanks everyone for your help.

Just an update...not sure why I didn't think of it before, but I've hooked a USB hard drive to my Airport Extreme and am backing up her laptop on that. It works very well, except that I find I cannot access the hard drive by two different accounts on the same iMac.
I've posted my issues here is anyone would like to chime in...

I hate to have to tell you this, but backing-up that way is often unreliable, and is not supported by Apple. See Using Time Machine with an Airport Extreme Air Disk.

Yep, I read that. I am not overly worried. I'm backing up the laptop in case something goes wrong as a matter of convenience. If I lose the backup, oh well. I am not that bothered.

Then, my next question would be how to back up an MacAir without having to physically connect a drive? I would have thought one of the advantages to having a MacAir is to do things wirelessly. Of course, I could go out and buy a Time Capsule, but I don't want to spend that kind of money.

You can back up to a shared drive on another Mac, a Mac Server, a Time Capsule, or a network drive (NAS) that supports Time Machine (although that introduces some other considerations, and I wouldn't do it, but many folks do it successfully). See Time Machine - Frequently Asked Question #2 for details.

Well, I don't have a Mac Server and I don't want to buy Time Capsule.
I tried backing up to a shared drive on another Mac with mixed results (see original post above).
Let's see how long this USB drive attached to the AE will last. I'll report back my results.

Well, it only lasted about 1 week before I was getting an error. Really frustrating. How to back up a MacAir without connecting a hard drive directly to it, buying a Time Capsule, or going through a bunch of complicated steps!
