Try this.
Stop the service, and edit the config file with notepad.
Set the cpu usage to 80%, restart the service, and see if it
still kills the wireless card. I had to do that with my dell 9300 laptop. If it works then, you can adjust the settings up, until the point where it kills it again.
I notched it down to 60 and it still did it. ALSO, my config was again wiped out. I really dont understand that one bit. Im not going to use the 5.04 console version and going with the 5.02. Lets see how I fair with that. Thanks.
