Ethernet quit working after Yosemite upgrade
After upgrading to Yosemite, my ethernet word connection quit working. Error says "Either the cable for Ethernet is not plugged in or the device at the other end is not responding." This happened once before after one of the dot updates to Mavericks. A subsequent update caused it to start working again. Any ideas?
iMac, OS X Yosemite (10.10)
