Ethernet card doesn't work after sleep resume

[akruglick]

Hi,

My onboard ethernet port died a few years ago due to a power surge I believe. I installed an Rosewill RC-404 (Realtek RTL8169) PCI ethernet card with the AppleRTL8169Ethernet.kext. The card worked fine until I upgraded to Mavericks. Now, when I resume from sleep network preferences says there is a cable unplugged. I need to restart for the internet to work again.

Anyone have any ideas on why the PCI ethernet card is not working after resuming from sleep?

Thanks

OK so I ended up buying a new Mobo for $89 (GA-Z77-HD3), which seemed to be the cheapest UEFI board I could find. Everything works now including sleep, magic mouse, and ethernet.

PCI-e ethernet cards seem to have trouble in these builds.
