Onboard LAN disappear when I boot High Sierra

9 posts in this topic

Recommended Posts

Hi

I use Z77.
 

I use ASRock Z77 Extermr4 board and BCM57781 LAN (Onboard).

 

It was ok until High Sierra.

 

But after install High Sierra, The onboard LAN keeps disappearing.

 

 

 

It does not seem to have LAN at all.
 
On linux, lspci, on windows, device manager and on mac lspci/ioregistryexplorer....
 
There's no lan.
 
 
The only way to get it back is the CMOS reset. (Not a bios lload default menu, H/W jumper clear).
 
 
 
I wonder if others have this problem.

Same issue on my brother Z77E-itx using Fakepciid. I think We should wait an update of this kexts. A lilu plugin could be a good solution too

No, I did not use FakePCIID.

Below code is for 10.13, but also disapper using 10.12.6 IONeworkingFamily and Child kexts.

 

 

I use Clover FakeID and Onfly binary patch

<key>FakeID</key>

<dict>

<key>LAN</key>

<string>0x16b414e4</string>

</dict>

and kextstopatch

e8ea9affff668983 -> b8b4160000668983

e87b9affff668983 -> b8e4140000668983

e8609affff668983 -> b8b4160000668983

 

I think it's clover bugs or something else....

same issue here also with Z77e-itx.  LAN disappears on reboot and only cmos reset brings it back.  Let me know if you figure out a fix.

not really a solution, but at least on my rig a cold shutdown and reboot is enough to bring it back.  cmos reset wasn't necessary after all.

BCM57781 is borked for me to on High Sierra, no ethernet detected. Also the device at times can vanish and be non detectable in operating systems outside of OSX after a reboot. I've found simply toggling on/off the onboard LAN from UEFI BIOS works too in getting it to return.

Any known solutions yet for High Sierra?

You guys booting with Clover?

 

If so put this IONetworkingFamily.kext in the Kexts/Other folder.

 

If using Chameleon put IONetworkingFamily.kext into /Extra/Kexts ( or wherever it goes)

 

This should fix it up.

 

edit:

IONetworkingFamily.kext is what I use to get my IntelMausiEthernet.kext and RealtekRTL8111.kext to work.

 

This kext? ...Huh, did you forget to attach the kext to your post?:

 

Please do share. Unless someone else has another solution?

 

Best Regards,

 

Jason

Just copy the one out of S/L/E to your EFI/Clover/kexts/other folder.

Your lan should come up as en0 even on a clean install.

You need that for correct App Store and iMessage/FaceTime connection.

That is where I have my kext, I am using the latest fakepciid.kext for the BCM57781. Kext's relating to IONetworking* at /S/L/E are untouched and clean.

 

Yet the issue still persists...

      I wasn't able to enable network support on installation; I installed the BCM57781 kext for my onboard Asrock x79 extreme6 and now when I go into network preferences it just hangs on the spinning colour wheel. Is there other kexts I should remove? Any input would be much appreciated..

      Thanks

      Hi all, new the community and just installed 10.9. I'm running into some trouble getting the ethernet up and running. I've tried a bunch of kexts but none of them seem to work. Not sure if I don't have the right one or I'm doing something wrong. 
       
      Also, I'm not sure how to get my GTX 660 working. It is recognized in the system profile, graphicsenabler=No  but when I switch to in the bios, I get hung up on the loading screen.
       
      If anyone has any suggestions please let me know.. Thanks!!

      hi,
       
      I have a ASRock Z77E-ITX mainboard and last week updated to 10.8.3 without any issues (combo update). I only have to install the IONetworkingFamily.kext (which i also used in 10.8.2) and audio kext, but i have some strange behavior with downloading files and for example youtube movies. I can easily reproduce the error to do some speedtest @www.speedtest.netand do a test, the test wil abort after a while. also download a speedtest file of 1GB it says network connection broken. On some youtube movies i see that some movies are not fully downloaded and abrupt sometimes. i have tried to reinstall the kext (first deleted), but also same issue. i also cannot find a newer version of this kext: "IONetworkingFamily.kext BCM57781" i use (BuildVersion - 602).
       
      someone any idea? tips?
