[En-Nut-Discussion] Disconnect Cable

[Dusan Ferbas]

Hi Hermann,

I am not sure if this can be an ARP problem. In any case you can try 'arp 
-d x.x.x.x' on the PC. 'arp -a' gives you list of arp table. Deleting en 
ARP entry will force PC to send an ARP request. If this will wake up 
communication you will know st more.
