- Download the Realtek 8187L from Alfa website or your CD media. Note that the driver must be for OSX 10.5 or later.
- Unpack the zip file and install driver by double clicking the install.pkg
- At the end of the installation you will encounter an error that the extension is not supported. Kindly ignore the error and proceed to the next step :)
- Restart the computer.
- Open Terminal and enter the following commands:
cd /System/Library/Extensions sudo chmod -R 755 RTL8187L.kext sudo chown -R 0:0 RTL8187L.kext exit
- Restart computer once again.
- Plug in the Alfa USB wifi device.
- Open Terminal and enter the following commands:
sudo kextutil -t -v /System/Library/Extensions/RTL8187L.kext exit
- A network window shall pop up where you configure a new profile or connect to an existing wifi hotspot.
- You have now configured your Alfa USB wifi adapter!
Note that each time you reboot the computer, you need to repeat step 8.

Since the netgear WG111V2 has the same chipset does the same work for the netgear card as it does the alfa card or is it specific to the alfa card.
I dont see why it shouldn't work?
Thanks
Hi Anonymous this should work on all Realtek 8187L chipsets. Moreover, the procedure described here should work with all Realtek chipsets - just use the relevant drivers.
This didn't work for me. On step 8 I get an error:

Any ideas?
What OSX version do you have? First thing I might try is to load into 32bit by pressing the 3 and 2 keys at the same time during bootup.
Nope, no luck.

The kext loads but I don't get a popup window...
Ok I just had to load the Realtek application and it works fine. Thanks! One question, do I always have to be in 32 bit mode to use the card?
No not required - only during installation. Should work on your architecture. However you still need to load the kext everytime you need to use the card, followed by launching the Realtek application. I did an Automator workflow application. If you need the code just tell me.
Hey. Thank you very much for this how to.
Can you please post the Automator code?
Does this work in OSX Lion 10.7
@Anonymous 1: This is the code to use for your Automator script:
on run {input, parameters}
do shell script "kextutil -t -v /System/Library/Extensions/RTL8187l.kext/ > /tmp/alfa.out 2>&1; open /Applications/Utilities/Realtek_USB_WLAN_Client_Utility.app" with administrator privileges
return input
end run
@Anonymous 2:
Yep it should work although I have not tested it. If you can get back to me and the readers about the outcome, we would really appreciate it :)
It works with OSX Lion 10.7 but only in 32 bit kernel.
How can I get it to work in 64 bit kernel with a 32bit kernel extension?
Boot up in 32 bit mode - i believe by pressing keys '3' and '2' while booting up.
i'm running 10.6.8 and trying to install awus036H antenna.
when following your checklist on step 5 when I enter the first sudo chmod line terminal asks me for a Password. The weird part is i can't even type mine in. I've even turned off my account password.
okay disregard last, i figured out i just put in my password.
Step 8, line 1:
I get "No kernel extensions specified". however if i type in /system/library/extensions/RTL8187L.kext it says it is a directory.
hello guyz i am using mac os 10.7.4 and i did all the steps but the thing is when i dont get a popup window just the same thing with the anymouse frined .. any thing may help ? plz :D
yoy thanks a lot bro i finnally got it to work !!!! and all thanks to you
This work on mac os 10.8?
I'm using unibody polycarbonate macbook, which have Snow Leopard pre-installed. Was enjoying AWUS036H since early this year until yesterday I decided to upgrade to Mountain Lion.
After the upgrade only I realized that Realtek USB WLAN Client Utility wasn't working as usual. I totally forgot about the driver which have issue with Mac OSX above 10.6 version.
Anyway, I have follow the step 1 and at step 8 I encountered this error messages:-
