We've tried the Fn key combination... It indicates on screen that it's working... but it isn't.
The updates might be the cause... but I don't think so, because, after I'd "fixed" the problem a week or so back, by using system restore, I applied all the updates that were then needed... and it was still OK... so it wasn't one of those updates that did it...
Of course it may have been one since, but that would mean the problem has been caused by a different issue to previously, which seems unlikely I would have thought.
I posted originally in the vain hope that someone may have encountered this specifically on this make/model.
I await further input, and I'll post with any progress... though this wont be until next week!
I think I'd be inclined to un-install it from device manager and then reboot and let the OS find it and automatically install the drivers again , another thing to look at is whether there is a program loaded to manage the wireless connections as well as / in opposition to whatever flavour of Windows your friend is using , they can often conflict .
