I have a wpc54g wireless adaptor that is only a few months old. It has worked fine until the last 2 days. Now, my computer freezes up frequently, and is released the instant I remove the wireless adaptor most of the time. After a bit of research, it seems this is related to my wireless card. I have had to power off my computer several times instead of shutting down properly, which I don't like to do. Also, this almost coincides with my latest window update. I checked for an updated driver, but didn't find one. I haven't uninstalled and reinstalled the driver. Can anyone provide some help for what I need to do to stop this problem? Thank you.
