It took me a while to figure out that I didn’t have a driver problem.

I was looking everywhere to find the switch for the wifi on this HP Elitebook 8730w, but it turns out the LED icon in the upper left that shows the WIFI status IS the button, but clicking it does nothing.. why?

Well, b/c HP is using “LAN/WLAN switching” which means that it automatically turns off the wifi connection if you are plugged in.

Just unplug your network cable and your wifi card will enable!
