@Dave: Sounds like the Bad-Ethernet-Cable-Issue we saw from time to time.
Thanks, i will try with a different cable. I would be very pleased, and also feel kind of dumb if that solves the problem.
@Dave: The thread is about the internal cables. But checking operation with a different cable may help as well.
Thanks for the info, i didnt realize there was a link in your first post. I spoke with a AH dealer briefly today about it hoping to find out more soon.
