And, as so often happens in these cases, having taken the time to 
describe the problem in some depth, I now have a fix from a completely 
different source.

The wireless network config screen for the BeBox has an "allow 
multicast" checkbox. That was, of course, checked. One of the 
suggestions from the Be forum was to uncheck it. That was unintuitive 
(surely we don't want to disallow multicast) but I tried it anyway.

The result was, as I suspected, to make things even worse. Now the PCs 
couldn't even ping the router (although they could still see the 
internet). That made it hard to get to the web-based config screens 
until I used a wired connection. I could then re-check the checkbox to 
allow multicast again. And that fixed the problem. Now everything can 
see everything else.

So it seems that the firmware upgrade left that option in a dodgy state. 
And turning it off and on again was needed to unwedge it.

Thanks for the suggestions everyone.
