my experience, frustration and bias follows.

i have had this problem on several occasions;

 - it happens with HP ProCurve Switch 2424M 10/100 Switches,
 - it does happen to other 10/100 switches,
 - the card works fine in 10Mbit mode,
 - the card can not determine the duplex mode, so assumes half.
 - i have not found a way around this, other than getting a switch that
   works properly. 
 - this does not appear to be a fault with the card, as
   other cards fail to talk to this model switch properly too.
 - it happens under windows, linux, freebsd, openbsd ...

FIX;

 - hard set the port on the switch in full-duplex mode 100Mbit,
 - and hard set the card in full-duplex mode 100Mbit,
 or
 - hard set the port on the switch in 10Mbit,
 - and hard set the card in 10Mbit.

yours,

kim
