rtl8187l on snow leopard

Install the 10.5 driver package (which doesn't install the kext correctly).
Drag and drop the rtl8187l.kext from the sle folder to the desktop.
Drag and drop the rtl8187l.kext from the sle folder to the trash.
Use kexthelper to install the rtl8187l.kext properly from the desktop.
There are other methods,but they require more typing- using the terminal.

Ive uploaded this installer for you it worked on my iatkos s3 installation perfectly :) im running 10.6 so if you have over 10.6 it should work a treat! Hope you get it fixed

RealtekRTL81xx-0_0_67%2B.pkg.zip

The pid 8187,vid 0bda isn't in the kext so the extension never gets loaded.
I reloaded the 10.5 app and driver my way.
