ethernet cable connect yosemite iMac2011
Hi,
i've got a problem with the wired ethernet on my IMac 2011.
i always got the message - Cable not connected. But the Port is OK. The Cable is OK (test with another PC)
My OS is Yosemite 10.10.3
I tried to change the environment - no success.
Has anybody a solution about this problem?
Thanks
iMac (21.5-inch Mid 2011), OS X Mountain Lion (10.8.2)
