Legacy Broadcom 43xx fix for El Capitan

[digital_person]

Apple changed something in the CoreWlan.framework and the trick with airportd from Snow Leopard doesn't work now.

I wrote a simple menubar app like the Apple's WiFi menu.

This menubar app uses AirPort.framework from Snow Leopard instead of CoreWlan.framework and Apple80211.framework from El Capitan. 

 

Here is my step-by-step guide how to make Wi-Fi work:

 

 

• Put your working IO80211Family.kext from Snow Leopard into /System/Library/Extensions. 
• Disable airportd:

  sudo -i 
  (enter root password)
  cd /System/Library/LaunchDaemons/
  launchtl unload com.apple.airportd.plist
  mv com.apple.airportd.plist com.apple.airportd.plist-disabled
  

• Put AirPort.framework into /System/Library/PrivateFrameworks/
• Rebuild kext cache. Repair permissions. 
• Reboot    

 

 

There is also a console version of the menubar app with some advanced options like iwconfig from linux. For example you can set a different locale code to get more channels, change power save mode or manually set transmission rate.

Here is a build with default Apple82011.framework. Use it if you have OOB wlan and want to change locale code etc.

will this work on previous OS?

works fine (lacks password storing) but i can't find a way to fix nat

 

this means i can connecto to any network but since no nat settings i got no internet connection only access to router gateway

I've add new version of the application in the first post. I've rewritten almost 90% of the GUI code. I also add password storing and some other stuff.

Unfortunately, I have no any routers in my possession, I've tested the application with my iPad's Personal Hotspot, my another hackintosh 'Internet Sharing' and also with a plain Computer-to-computer connection to transfer files. In all those cases I haven't experienced any problems.  So I have no idea why it doesn't work with routers.

Have you tried to change TCP/IP settings in Network Preferences?

I've tested it under 10.8 and 10.9. But I have no reason to use this solution under  OS X below 10.11 because you could easily make Apple Wi-Fi work by just replacing airportd and wi-fi driver with older versions. In fact i've never install 10.10, maybe it has the same wi-fi problem as 10.11, so if you talking about Yosemite I haven't got any answer to your question.

I had same issue, that I could only access my local network. I solved that by disabling IPv6

networksetup -setv6off Wi-Fi

I've also set IP address, gateway and DNS manually

This thread is a very good solution for old cards. It does work on 10.11 and might be a good solution when apple decide to disable cards on future updates.

Plz some moderator bump this thread to page 1.

I dont wanna see all this good work lost

Have you checked this solution with Sierra?

[padshool]

I have same issue on El Capitan : have ssid of network but not have internet...

 

'networksetup -setv6off Wi-Fi' does not works for me. (Perhaps a locale setup to put ? : I'm French)

 

 Thanks for your work  Digital_Person !

I got this bug too. Few weeks ago, after I replaced my old HDD and reinstalled El Capitan from scratch, I wasn't able to connect to the internet only my local network worked.

I found solution to this problem:

• Go to System Preferences -> Network -> Wi-Fi -> Advanced
• Manually add your Wi-Fi network Name and Password
• Apply changes

This helped me.
