Hi

I did look into the bios to see that everything that might stop the
adapters working was enabled. As regards bios update when I visited HP's
support site no bios seemed available for an Ubuntu machine. There were
downloads for win 7, xp, vista etc. Perhaps this machine works better
with this older bios ?

Regards
Kevin
