Need updated driver that supports WPA

Question

I am trying to connect to a wireless network using WPA. It seems as though my driver is old and does not support WPA. I am currently using the driver version 7.43.0.9. In doing some research, it seems as though I need to download the newer version 7.82.0.550 (22/9/2003). I am continually being directed to www.agere.com, which has now merged with www.lsi.com. I am having a hard time navigating to find what I am looking for on LSI.com. Can you help me find this newer driver so I can connect wirelessly?
