Just upgraded to 10.9 and cannot get the internet working.

I have been through almost every topic containing BCM57781 and tried every kext I could and nothing.
My Specs:

CPU - 3770k
MOBO- Z77 Extreme4
Memory 16gb ddr3 (only 8 is in right now)
GPU - GTX 660 (removed for now)
Help!! Thanks!

I am also stuck. I have Mavericks. Got a BCM57781 on my Asrock Z77 Extreme 4. Can't get it to work.

Any takers?

It semi-worked for me. It was able to recognize the ethernet card but couldn't connect to the internet. I messed with something and now it doesn't even recognize the ethernet card. fml.

Same here: everything works fine (even Sleep, which has never worked before) except that I get no ethernet connection in Preferences - Network, and I can't create one.

i7 3770K - Z77 Extreme4 - 8GB DDR3 - HD 4000.

EDIT: My ethernet card was seen by the OS thanks to the kext posted by AlexBes (link: http://www.insanelymac.com/forum/fil...e/79-bcm5722d/ ): now in Network preferences it seems "connected", but I still can't surf the web nor reach the router's address, even configuring IPv4 manually.
On the other hand, my router sees an "unknown" device connected.

EDIT2: I GOT IT!!! :headbang:
After installing the BCM 5722D kext and rebooting, I went to Network Preferences and created a new ethernet connection. After that, it remained "Not connected", so, I flashed the BCM57781 kext posted by rccollins, rebooted and... It's working!
I don't even know if the first kext I installed was necessary... maybe the BCM57781 kext was a patched version, rewritten for Mavericks :)

I'm in the same boat here. My ethernet is recognized but can't get the ip address.
