My laptop wouldn't connect to the wi-fi signal today.....disaster. Spent ages phoning IT literate friends and tried all their possible solutions. Eventually, 10 year old grandson told me that I had inadvertantly turned off the wi-fi signa,l which is on a tiny slide switch on the front of the computer!
Sort of. What you'd actually done was turn off your laptop's ability to pick up wi-fi, rather than the wi-fi itself. All modern laptops have this feature...
Thankfully .. Dell now mark them .. and are properly grouped with the rest op the op. keys.
Daft thing to do .. designing/putting a wireless connect button on outside.
