Why does my laptop not detect WLAN?

Question

I have an HP Pavilion tx1320us and for the past month it has been unable to detect the WLAN wireless card. I have called HP and it has gotten to the point that I had to get a new wireless card which has stopped working now as well. I look into the device manager and the Broadcom software does not appear and my computer tells me that I have to connect the card which is already in place. What is happening to it?
