Hi,

I had the same errors too when I started to test with the
4port card.
After changing the 200M UTP cable that was all put in a
corner for a 2 meter cable the problems went away.
I read on some previous posts from Klaus-Peter that the CRC
errors mean bad cables. In my case the way-too-long cable
from the NT1 to my * box was the cause.

Maybe this can be of any help
