ZD_Wlan_Config.tiffI have the same USB WLan adaptor.
You should use this driver and software: ZD1211 USB Wireless Lan Driver drivers from http://mac.softpedia.com/get/Drivers/Zydas...SB-driver.shtml. See also http://wiki.osx86project.org/wiki/index.ph...10.5.2#Wireless for more info.
After installation, you will find a Wlan application in you Utilities folder.
When properly installed, the Wlan selector application will open when you boot your computer.
You can set some parameters according to your Wlan network, security settings etc. in the application window.
See screenshot in uploaded image.ZD_Wlan_Config.tiff
Persevere and you will get things working.
