You need to find out what wireless chip set you have. There are several ways to do that. Open a konsole and run as root 'lspci' and look for your wireless card information. Post what you find.
If you can boot winders, look and the information provided there. Since it is a system provided by a major manufacturer, go to their web site and look for the hardware documentation. In there you should be able to find all the specs on your system including the wireless hardware.
Once we know what you have, we can determine if there is a native linux driver or not. If there is, you use the command 'modprobe' to load it. Then you configure it.
If there is no linux native driver, then the last option is using ndiswrapper. Ndiswrapper is used to load winders drivers in linux. Then you configure and activate.
It all starts with the research.
