iMac Ethernet Problems
I have an iMac 2011 3.1 GHz.
The Ethernet Port works (sometimes).
But sometimes (every 1-2 Days), the Ethernet Port suddenly "turns off" (after a restart).
During this phase the iMac says "no Ethernet Cable Connected" and I am unable to open a new Ethernet access in preferences/Network.
On top of that it says in "Hardware" "NO ETHERNET PCI CARD INSTALLED".
Then I have to do a "PR-Reset" or a start holding down "SHIFT-Key" to bring it back to work.
I am totally confused.
The Ethernet port semms to be OK, I think this could be a software-Bug?!?
