Hi Paul - yes, I've already changed the cable. I suppose it could be the
router, or the board, but somehow I have good faith in hardware and
absolutely zero faith in software :-)

Anyway, for the moment, I've just set the interface to 10Mbit and it's been
rock stable for 24 hours.  No great loss, as even the other machine on the
network is wireless, so the 10Mbit link doesn't really constrict things when
transferring stuff between them.

Hmm, 100Mbit ethernet was one of those bread+butter technologies I had
believed was so mature and reliable that no-one even had to think about it
any more. Guess I was wrong again!
