Janitha Kulasekara :
I couldn't find that hot key to on/off wifi of my laptop. If anyone knows be kind enough to share. Thanks in advance.
Titillating is correct. You can also turn it off in the BIOS for a more semi-permanent solution(not wanting kids or unauthorized users to easily turn it back on, etc.)
This link shows both methods, just follow the directions to the BIOS menu and turn it to Disabled instead of Enabled,
