To make ethernet work, have you installed AppleIntelE1000e.kext or IntelMausiEthernet.kext? Also, what is your WiFi card?

So i got my 5 ghz channel to work by going into my network settings and changing the channel from auto to 48 and my wifi card (TP Link N900) instantly picked it up. I've tried installing AppleIntelE1000e v3.3.1, but no luck. How do you take out a kext you installed? I'm still getting used to clover config and installing kext.

I'm getting some disconnects with the 5ghz band. Anyone have issues with stability?

You go to /System/Library/Extensions/ and then remove the kext
