Again, as I said, post the output of 'lspci -v'. The brand name of you 
wireless card is completely, and utterly meaningless. Many different brands 
will often be the same exact wireless chipset underneath, and the same brand 
may ship with completely different chipset hardware, over time.

Unlike Windows, Linux does not use the "download a driver off the 
manufacturer's side, and install it" model of hardware support. There are 
some scattered manufacturers that allegedly offer drivers for download, but 
those are rarer. You will find that those drivers are for specific versions 
of Linux with a specific kernel version. Linux drivers must be compiled for 
each kernel version. Given that most distros issue updated kernels every 
month or so, you can easily see why the Windows model of driver installation 
does not work (and there are other reasons as well). With Linux, either the 
hardware is suppored by the kernel, or it's not.

So, as I said, the only way anyone would be able to help you is if you post 
the output of 'lspci -v', first. Chances are you only need to set up your 
firmware files.
