Well, I don't have a URL reference... but there's a good reason why. The reason you aren't getting any answers out of Cisco or Gigawave is because, well, there's no good answer.
There is nothing at all about roaming in the 802.11 standards. As such, all wireless adapters have their own algorithms for determining when to roam. And companies tend to keep these algorithms secret, because it's company IP.
As far as I know, you cannot debug either Windows or Cisco client adapters when they roam. There is no way to receive insight as to why they roamed, and this is by design.
This isn't exactly what you wanted to hear, but it's how it works I guess.
Most higher quality chipsets have the ability to adjust roaming aggressiveness. If they don't, we pretty much recommend a newer chipset. The chipset manufacturers base their algorithms on basically 3 factors. 1. Signal strength. 2. SNR, 3. Client load on the existing AP. If the threshold for any of these are violated the client chipset goes into active scan mode and seeks a better AP. If none is found it will stay where it is. If a better AP is found the process of reassociation and reauthentication (if needed, not needed with LWAPP solutions usually) to the new AP.
I wanted to share a book i am in the middle of reading. Its "Secure Roaming in 802.11 networks"
Its a great book ... talks about the driver, chipset, clients, etc ...

Q1 How does the CB21AG using the Aironet Desktop Utilty 22.214.171.1249 determine which 1242-LWAP AP to associate to? Can I debug the decision it made?
Using the (Aironet) Cisco Desktop Utility, you can configure which AP's you want to associate in a particular order. Otherwise, the CB21AG card will associate on the AP with a stronger and stable signal.
