How do I copy a .kext file to the extensions folder

[kerjuk]

I have copied out the kext io80211family.kext to make the change to allow my atheros card to work pci168,1014 or very similar, but when I try and copy it back in to the extension folder it fails.

I have been here before and I found a thread that discussed it using the terminal utility.
using CHMOD and alike. I can't find this thread again so wonder if some kind person out there will help me out. I can see my Atheros card in the network setup but it won't let me active the Airport....

Cheers in advance.

Use kext Helper ... here

sudo cp -r <filename>.kext /System/Library/Extensions

sudo chown -R root:wheel /System/Library/Extensions/*
sudo chmod -R 755 /System/Library/Extensions/*

Might also want to delete your extensions.mkext file in /System/Library

You can also apply these commands to /Extra/Extensions
