wifi card disappears from the hardware list, only mobo replacement can bring it back.

unfortunately it happens about 12-14 months into the life of the laptop, when normal warranty is expired.

there are hundreds of posts on the internet related to this, and new ones are added each day.

and yet HP fails to admit that there is a systemic problem that they are responsible for.
