Why then do I notice better behaviour with EXACTLY the same equipment ?
In fact nothing has changed except booting to a different disk and OS.
PS: As an electronic/electrical engineer, I find it very hard to believe
hubs are half-duplex.
All help is greatly appreciated,
Murray.

^^^^
Hubs are half-duplex devices, use "ifconfig ne2 media 10baseT".
