GA-Z77-DS3H - clover El Capitan - ethernet does not work

[tadmorguy]

Hi,

My specs are: GA-Z77-DS3H, GTX 650.

Just had a clean install of Eli Capitan with unibeast (Clover).Tried all of the atheros ethernet drivers multibeast offers but none of them works and the ethernet card is not recognised, hence, I do not have lan connection.

However, I've noticed a weird behaviour, when I boot with the USB flash drive (which has the unibeast on it) connected , the ethernet card is recognised and I have an internet connection when I plug it and restart, ethernet is gone again.
The boot is done via the SSD drive and not via the usb drive.
Note that when I boot, I select the MAC OS-X option (after F12 is pressed).

Anyone has a clue how to resolve this?

thanks,
Guy.

Yes, boot with the USB and when you reach the desktop open About this Mac.
In System report look at Ethernet and you will see the kext that is loaded.
Install that kext into /Library/Extensions on your hard drive.

thanks for the quick reply !!!

I assume the following are dummy questions... , however, up till now, I never had to deal with such operations...

How do I get the kext file? from where?
How do I install the kext file?

many thanks,
Guy

I've review the system log and found this (when the network does not work):

Does it help to understand the issue? as it seems that the kext is already there.

How do I install the kext file?

Delete AtherosE2200Ethernet.kext from /Library/Extensions.
Delete AtherosE2200Ethernet.kext from /EFI/CLOVER/kexts.

Download ALXEthernet and place it on the Desktop.
Download KextBeast and run it - Choose /Library/Extensions as the install location.

Rebuild cache with Terminal :

sudo kextcache -system-prelinked-kernel

and

sudo kextcache -system-caches

Restart and choose the without caches option from Clover.

Be aware that there are two versions of the Z77-DS3H and this solution will only work for one of them.
If it does not work for you then you probably have the other version and should use the forum search tool to find other Z77-DS3H Ethernet solutions.

Good Luck

Great, thanks a lot !
it solves the ethernet card issue ! yet, I didn't choose the w/o cache option in clover, as I didn't find it and also didn't find the EFI folder neither to remove the Kext.
I have some doubts regarding my install as I cannot boot to the "Mac OS-X" anymore (I've re-installed the os-x) and I need to boot to the SSD driver where this open the "launcher" screen in low resolution. Also, in the first install, on the login screen I had my user and also Guest user option and this does not show up... weird.

Does this matters? (where the boot is performed)

I found how to remove the bootloader, I will try to re-install after removing it.

This worked for my GA-Z77X-UD5H and Sierra! Been pulling out my hair for weeks trying to get my Atheros ethernet to work and couldn't remember what kext I used with Mavericks through El Capitan.
