No, I don't have a physical on/off switch for my WiFi card. I have a Dell Laptop.
Are there anymore suggestions? I'm greatful for the help I'm receiving.

Thank You One And All

I.m having the same problem as Slartybart. I did as you suggested and it still wouldn't turn off. I'm totally disconnectd from the internet on my laptop.

Is there any other way to fix this...
