The article states 1gb lan. But there are two versions of Intel 2.5gb lan. The first is defective and can't be fixed. The second is rare as it was just released. I'm not sure which boards have the fixed Intel chip. But I'm not going to push my luck. The realtek is known to work.Is there a difference between 2.5Gb realtek and the 2.5Gb Intel chip the board has?
