maybe you have some problem with the frame size on your internal nework...

frames to the outside world will be less than 1500 bits - are you using 
jumbo frame gear?

could also be a problem with auto negotiation - use mii-tool to see what 
your card negotiated for a speed.

do you see errors in the statistics for ifconfig?

you could also try a pcmcia network card to see if the problem is with 
your card.

finally - try a bootable linux distribution to eliminate a software problem.
