No internet connection after installing yosemite
After installing Yosemite, I have no internet connection. If I hold option key, my wifi description shows Internet as unreachable,although all my bars are dark and the rest of the settings look the same. When I connected via cable, it did not show an Ethernet connection. My pc and iPad work fine,so it isn't my carrier. Anyone else have this problem and know a fix??? Thanks so much for any assistance..
iMac, Mac OS X (10.6.8)
