Can't get fn+f2 to work properly on Dell with Atheros

[dwschoon]

I have a dell inspiron 9200, and i added an atheros wlan card purchased from ebay some time ago. The card works fine with the latest drivers from this site, except that I cant control the wifi led, or disable the card properly with the fn+f2. The led stays on all the time. If i use the fn+f2 combination, it appears to disable something, as I cant get any network activity, but the icon in the system tray still says connected and the led is still on. I have searched a lot on how to mod the inf of the driver to fix this, but cant find anything. I ran that nerd tool and this is what it came up with.
