Ethernet re-appears disconnected at start-up

[Showcker]

I recently succesfully installed iAtkos S3, and I being having some problem with my internet correction.

When the computer starts or restarts, my internet correction doesn't connect automatically, I have to go to System Preferences then Network, and when I do, the network that was working after i shutdown, doesn't connect, and a new one is detected.

 

 

In this example "Ethernet 2" was the connection working before I restarted.

 

Why could this be? How can I fix it?

Your Realtek RTL8201CP chipset is a single-port PHYceiver i.e. driverless hardware device, driven via the MOBO Network controller (MAC), so given your P5N73-AM with NVIDIA GeForce 7050 / nForce 610i chipset, I assume you installed eno's nForceLAN.kext.....

 

I am also assuming that your nForceLAN kext is (which it MUST be) physically located in /System/Library/Extensions/, OR in Extensions.mkext in /System/Library/Caches/com.apple.kext.caches/Startup/, OR in both /System/Library/Extensions/ and Extensions.mkext........

 

If present, remove forcedeth.kext and nForceEthernetController.kext, and remove nvenet.kext, or rename it to nvenet.kext.bad......this is because nvenet loads even when another Ethernet/LAN kext has already been loaded for the hardware. In 10.5.7 and later, including 10.6.x, look in /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns.......this is a new location for nvenet.kext; prior to 10.5.7, this kext was not in IONetworkingFamily.kext.......

 

In Terminal, type

 

cd /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns 
ls
sudo mv nvenet.kext nvenet.kext.bad
ls
sudo touch /System/Library/Extensions/
exit

"ls will list the files in PlugIns"

 

Reboot with -v -f

Thanks for the quick reply!

nForceLAN.kext is at /System/Library/Extensions/. Sorry, I don't know how to look inside Extensions.mkext, can't open it from Finder, so I don't know if it's there also.

 

Didn't find forcedeth.kext and nForceEthernetController.kext, at least not in /System/Library/Extensions/. Couldn't find them with Spotlight either. Where should they be?

 

I did this without any complications:

cd /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns 
 ls
 sudo mv nvenet.kext nvenet.kext.bad
 ls
 sudo touch /System/Library/Extensions/
 exit

 

I couldn't reboot with -v -f. When I write "sudo reboot -v -f" at terminal it said:

reboot: illegal option -- v
usage: reboot [-lnq]

 

Thanks!

UPDATE:

It worked!

Don't know why, but upon the first restart the problem persisted, now after a second reboot it worked perfectly.

 

THANKS AGAIN!

Glad to help........ Also suggest that you now use Disk Utility to repair OS X permissions.........

Done!

And a for future reference, what's does the "Repair Permissions" do? I mean, besides repairing the permissions, what do i "perceive" fixed?

 

Thanks again!
