GA Z87x-UD5H Working -everything[I think] except audio, sleep, Internet connectivity.
I installed the mac osx using Unibeast & Multibeast.
I Only added the Ethernet Parameter{ SORRY- I Don't recall which one-sorry I am 81years old]
Connected via Ethernet cable to router[Comcast router]. Becomes "unconnected"
For reasons unknown. Have to re-start to get it connected to ethernet again.
RENEWING the LEASE looks like it is reconnecting but it doesn't connect.

WHAT INFO SHOULD I PROVIDE FORUM SO YOU CAN HELP ME?
I don't know how I can fix this-cause I don't know why it is happening.

MACOSX 10.12.6 Playing like it is iMAC 14,2
Sees my ethernet"card" as
INTEL i217V PCI Express Gigabit Ethernet[actually the ethernet on the motherboard]
I have used several of my PCIe slots for USB ports.[ I don't know if that matters]

Here is what System thinks is there:
ethernet:

Type: Ethernet Controller
Bus: PCI
Vendor ID: 0x8086
Device ID: 0x1533
Subsystem Vendor ID: 0x1458
Subsystem ID: 0xe000
Revision ID: 0x0003
Link Width: x1
BSD name: en1
Kext name: AppleIntelI210Ethernet.kext [Does THIS TELL WHICH ETHERNET I CHECKED IN MULTIBEAST INSTALL?]
Location: /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleIntelI210Ethernet.kext
mDNS offload capable: 74:d4:35:81:81:62
Version: 2.3.0

I am using an audio USB plug in. Haven't gotten audio working yet.
Need to solve the Internet connection first-driving me a bit crazy.
I have installed a wifi adapter plug in. It works OK immediately after I install it but then goes away["not connected" after installation sleeps, just sits doing nothing, or after I have been browsing awhile. USUALLY if I continue browsing, use text editor, other misc activities the ETHERNET connection stays up]
This is how system see the wifi:
CoreWLAN: 11.0 (1200.31)
CoreWLANKit: 12.0 (1200.31)
Menu Extra: 12.0 (1200.47.1)
System Information: 12.0 (1200.3)
IO80211 Family: 12.0 (1200.12.2)
Diagnostics: 7.0 (700.5)
AirPort Utility: 6.3.7 (637.6)

INTERESTING AND STRANGE BEHAVIOR: Just after I reinstall the software
for the WiFi adapter the Ethernet connection is re-connected[not the WiFi adapter???]

This is the WIFI adapter software that installs OK but somehow gets lost soon after reboot:
EW-7822UAC_Mac_driver_v1.0.2.7
Version: 1027.4.b19.11182015

I will be happy if either the Ethernet connection to the Internet or the WiFi connection Internet connection would stay up.
The Ethernet connection is of course higher throughput [when working]
ANY IDEAS OF WHAT I CAN TRY?

ANY MORE INFO THAT I CAN PROVIDE THAT MIGHT LEAD TO FIX ?
 
Can you share your KEXT file?
I have same motherboardwith you.
Thanks a lot!
