Thanks, I will try ethtool.  By the way I needed 10Mbps because I'm trying to 
communicate with an old system which only supported 10.  I just dont 
understand why one laptop works fine and the other does not and was wondering 
if there was some standard reason why this might be happening.

Thanks again
