That might explain why I didn't ever get any similar behaviour when I
was running PPP, because that was on BSD/OS 1.1.

But I don't think it can explain how an ethernet-only router like mine

You learn something new every day!  ;-)

Next time my router chokes up I'll check this too -- so far since the
last long-lasting power outage almost three days ago there've been no
drops on any of my interfaces (and today I listened to a 128kbps MP3
stream for well over an hour while there were two of us browsing pages
on the web, one via the other connection), plus of course whatever other
"normal" activity was going on.
