OS X 10.9 on Dell Latitude E6400

[rachanta]

I have installed OS X 10.9 on my latitude E6400. Everything including ethernet and sound are working, except wifi.

I have BCM4312, so I used did various things including copying and AirPortBrcm4311.kext into the original IO80211Family.kext (and applying chmod +x), replacing IO80211Family.kext with my working Lion kext (I could never update to Mountain Lion and gave up). Replacing IONetworkingFamily.kext. After these procedures, the wifi does show up but I always get "Connection failed". I noticed that that the wifi connects only when there is no WPA Personal or WPA2 Personal key. But I cannot disable wifi security key in my network for security reasons.

Could anybody tell me what the problem could be?

Any luck? I have same issue with a lenovo b570. Everything is working. Can even connect to my wifi when unsecured. But when I secure it I get the issue!

Maybe it is because you replaced the stock IO80211Family.kext (which is never necessary)?

I did replace that kext. I think that's the only reason the hardware shows up. I also added the realtek82...kext (forget name). Can I find the original on my unibeast usb?

You should never replace IO80211Family.kext (it is a noob move). It is not even necessary to change (patch) it.

See here for the correct ways: http://www.tonymacx86.com/network/104850-guide-airport-pcie-half-mini-v2.html

Easiest is to just use one of toleda's injector/enabler kexts.

With out those Kexts the wifi doesn't show up, even tho my dsdt should have made it work apparently. How can I get the original 10.9 io80211family kext?

Then you did the DSDT edits incorrectly. For novices, it is best to use an injector kext instead of DSDT edits.

You will find it on your Unibeast USB in /System/Library/Extensions, assuming your USB is the same version as you have installed. Otherwise, do a fresh install.

Now go back and see if you can make it work using the techniques I mentioned. Otherwise, it will break as soon as you install an OS X update that updates this kext.

Like I said before, installing a patched/modified kext is NEVER necessary and will only lead to problems later on.
