Several "laptops" come with a physical switch to your the "wireless"
network adapter on / off so that is why the "switch" suggestion was

Have you tried un-installing the wireless card drivers and re-
installing them?

Do you have other USB devices on this PC? Do they work? Can you move

I have encountered this before but it was my incompatible USB ports.
USB ports / chips can "blow" so you need to know if they still work.
