powered ethernet cable is not connecting
When i connect my powered ethernet cable into my iMac it cannot connect and say that it has automatically found an IP address which is not correct and will not find my router.
When using the ethernet cable directly into iMac it works!!!
any ideas?? i'm using the latest OS X Yosemite (April 2015)
thanks
iMac (27-inch, Late 2012), OS X Yosemite (10.10.3)
