I'm having an odd issue with my AsRock Z77 Extreme4-powered hackintosh (OS X 10.9, but I've experienced this since 10.8.2). After some minutes of normal usage, my computer loses the internet connection... In order to fix it, I deleted the NetworkInterfaces.plist file, removed the Ethernet connection in Network Preferences and and re-addied it after a reboot, but nothing changed permanently. After a reboot, the issue disappears for several hours, but if I switch off the computer and, for example, I turn it on the following day, it disconnects again.
I also formatted my hard disk and reinstalled OS X, but after some days of proper functioning, I'm having this issue again...
I suspect it's something linked to the "Unknown error" of the App Store: before fixing that (with the method mentioned before), the connection worked flawlessly.
Please help me getting out of this situation
