You may have to backup your files and do a format and fresh windows install for the wireless card to work. You have a conflict somewhere, and the fresh install may get rid of it. Or you can splurge and buy a new ssd and use your old drive for data only. I like my ssd; won't go back to any magnetic drive again.
Seems to kind of work. The motherboard is still showing the red light but now I can detect my own network. I can connect every now and then, but not to the internet for some reason.
Edit: The wireless card is a Linksys WMP300N and the router is a Netgear DGND3300, if that helps.
