No it is the Realtek card, some of the cards have xtreme issues under FreeBSD, I know this as I have one on my laptop, works great at 100baseTX but at 10baseT/UTP I am lucky to get 80k/sec before this I was getting 1-2k/sec in between machines. My advice for desktop owners stay away from rl8139's & for laptop buyers make sure you read your specs. Thank god I am buying a switch this weekend for home.
