Hi - you probably already know this so I am just speculating here - since the AU defaults to include g devices, it sounds like you might be having a security issue - the AU defaults to WPA2 Personal - are you able to match this with your g devices? - WPA/WPA2 Personal is more compatible if you can't do WPA2 Personal - see the following password equivalents if necessary - I always use simple 8 character passwords for compatibility.
The AU also defaults to a WPA Timeout of 60 Minutes - this can be an issue with older devices and security types - some people set it to a higher number but this might make your network more vulnerable.
If the above does not apply then I would have the Extreme checked out.

Thanks for the suggestion but as I am already using WPA2 Personal then I don't think that that is the cause. Bear in mind also that there was no problem with these devices connecting previously - although,as I said, the Extreme always seemed kind of flaky.
Since I posted, I have also read another thread which talked about an issue where devices on g would disconnect when an n device joined the network. The ultimate diagnosis was a hardware issue.

I called AppleCare and they arranged a hardware swap. The Apple Store Genius did not have the replacement in stock, so I have to wait a few days. He did suggest testing whether the g antenna has failed by switching the other (5GHz) over to 2.4GHz to see if that solves the problem.
I have not had time to try this yet, but it might help your diagnosis!
