Hi,

Looking at the log you sent with the clock slips etc,

You have detected RAI - This means the other end is not happy with what you are sending.

Try testing your WIC card with a loopback plug
Just make this yourself by using a spare/old patch lead
Cut the lead and loop back pins 1 to 4 and 2 to 5

My type of straight cords that is the white/orange to the blue/white
and the orange/white to the whilte/blue.
