Hi there, I'm building a Hackintosh for a friend of mine, and everything went fine except that I can't connect to internet. His board is a Z77-DS3H so I installed an Atheros ethernet fix. The strange thing is that all seems right, I even have a green light saying "Connected" in the network settings, but still can't navigate with Safari. I have a WiFi USB dongle, the TL-WN725N, and downloaded the right drivers from this page http://www.osx86.net/files/file/3539-tp-link-tl-wn723n-v3-tl-wn725n-v2-usb-wifi/ .
Here are some images; in one of them the WiFi option in is clearly blocked, I believe it's because when I installed the OS I selected the option "This computer connects to internet with an internal Ethernet card" (the WiFi option was also blocked back then).
I hope you can help me with this, thanks!
