Plug the wired line from the PC into the laptop and enable the card with the "red x" in device manager.
If it connects to the internet with the lan cable then we have a wireless hard/driver/settings problem

You hooked up the wired connection BUT did you enable the intel 8255x wired adapter when you hooked it up?(right click on it and hit enable)
