When I set it to Auto detect, my speed is generally bellow 5mbps.. Which is why I have left it 100/full duplex.. In 100/Full duplex the speed is anywhere from 10 to 12..
I had someone with a intel PRO/100 VE adapter check his speed with a fios 15/5 plan and in his auto detect setting his speed is 20mbps. The computer is old, 2001 or earlier so I’m guessing its not a gigabit card.
