Been having a google around for what else might be on that site, nothing useful to me but a possibly handy tip in a MacRumours topic:

Post No 7.

Hmm... I haven't actually tried it, but it looks as though the "Upload firmware" dialog reads that .xml file to allow easy down-grading to versions that are OK for your hardware (?).

It may be that it shows versions you've used before, but the list on mine goes back to 7.3 and I don't think I've had it that long

edit:

After more thought, it's the iMac that's new-ish, I've had the Express for some while. Implying that the update history is kept on the device and read by the Airport Utility... not convenient to put the Extreme back in atm, but it'll be interesting to see if an appropriate file automagically appears when I can and fire it up...

In reply to a post by Adrian:

Bill, I was in touch with Billion support on this and they showed me how to change some settings that had been recommended on the web.

I finally got around to making the changes and everything seems to be fine, I've even got a spare homeplug again

One question- I assume the changes won't survive anything that initiates a "Reset to factory defaults"?

I saved the config in flash and a .conf file, but I suspect neither will help.

Weird...

As I said, it works.

But when you stop playing music (ie kill the Airtunes stream) the disconnect/join/unicast messages return, every 5 minutes.

Start playing again and the messages disappear... not really a major problem except that it fills the log up rather quickly!

I can't remember if it did it with the Extreme or not... I don't think it did, but could easily be wrong.

As a follow on, see this Airport Utility update.
