Already updated BIOS and wifi is enabled.
BIOS diagnostic test reported no problems.
Same problem in safe mode.
I have tried drivers direct from intel site also.
I've repeatedly tried all of the cmd lines also...
There is a guy on a DELL forum who listed 6 key drivers and a specifc order to
install them, which I have also tried to no avail.
I mainly use the laptop wirelessly to connect to my tv (to watch the footy from fsi)
and managed to get around it bouncing the laptop to my tv via the ipad and splahtop,
but the wifi not working is just insane. I'd rather not have to open the laptop up.
I'll wait and see if any other ideas emerge...
and yes, I have pressed ctrl + F2 !!!
