Yes, that is obvious. But a) Nick asked specifically for a network with both 10 and 10/100 cards, and b) I said "drop to lowest common denominator". The lowest common denominator of 100 and 100 is still 100... so I stand by my statement. As a minor point, a machine with a 10 card and a machine with a 100 (not 10/100) card connected via a hub won't talk with each other. > For light home usage, a hub is indistinguishable from a switch. Copying big MBs between 2 fast machines on 10Mbit should take noticably longer than on 100Mbit, otherwise you're probably right. Thanks Mark for the warning about switches and switches! Volker
