my processer amdthen windows7. but,no wifi softwere. how to instal. pls tell me....

So you have an AMD CPU, you need Wifi software, but you need to know how to install Wifi software... Insert drivers CD into DVD/CD drive and run the installation wizard. When the wizard tells you to plug in your Wifi hardware, plug it in and proceed. Reboot if the wizard tells you to and remove CD from drive upon reboot.
