I wonder whether the network was working fully when you booted up. It's
usually worth trying -n to prevent name resolution in case the nameserver
is playing up.

I wonder whether it's changed the settings on your 3c509 card. Have you
run pnpdsabl and 3c5x9cfg (names from memory) to set/check its configuration?

Well, after checking the card, and taking steps to prevent W95 mucking it
up in the future if it's still there (cmos settings), why not just
reinstall the system from scratch and then not switching it off. However,
there's no need to repartition the disk or reinitialise the partitions as
they haven't changed, just remount them, so it's quite quick.
