Sorry for the over-excited subject line, but after a week of experimentation, I think I've finally figured out what settings to tweak on my iBook to stop the frequent disconnects. I'll explain what I did below and I'd appreciate it if you could post your results here if you try it.
I'm using a 2004 iBook G4 with Airport Extreme that I bought off eBay two months ago. It was bought to replace an iBook G3 that died. The iBook G3 had an old Airport card and I never experienced this wireless dropping problem with that. When I got the new iBook, it started dropping the connection about every 10-15 minutes.
Here's what I changed that appears to have fixed it. Go to System Preferences and click on "Network." Under the "Show" menu, select "Network Port Configurations." When I first looked at this, Built-in Ethernet, Built-in Firewire and Internal Modem were all turned on and above Airport in the list. I only use Airport so I turned the other three options off and moved Airport to the top of the list. Click "Apply Now", close the control panel and reboot your machine. After I did that, my connection issues stopped.
Now, this was a fresh install of OS X so I'm wondering why it defaults to having all these ports turned on. Apparently having them on and above Airport causes this issue. I don't see why it should.
Again, I would like to request that if you try this, please post your results. I'd like to compare notes with others who try it.
[EDIT-- as pointed out below, these steps are specific to 10.4.11. I'll post steps for finding the network port config screen for Leopard later today.]
