Lost my RTL8111 with no reason. Please help getting it back

[bgg22]

Hi all!
I have ASUS H81-K + corei5 + rtl8111/8168 integrated lan

I installed sierra with unibeast and network worked out of the box after installation. When I installed multibeast for other drivers (no any additional network drivers), installed clover to hdd, enabled my GTX285 by replacing kexts, I lost my ethernet. It was listed as 'cable not connected', but if you remove the device, you can't add it back, no such. ifconfig -a also don't show it. So it just don't see it at all, including system report.

Tried to install realtek8111 driver from last multibeast - not helped.

Leds on lan not working after boot. on linux they work.

The card is 100% working on linux live cd, tried again after lost in macos.
Please help

Thank you very much! After running kextcache -i / I saw warnings about permissions on realtek's kext, it said it will ommit it.
sudo chown -R root:wheel on kext worked.

Now need to resolve audio. Can't find which Realtek's ALC need to install on
linux# lspci | grep -i Audio
