Using device manager uninstall, reboot and reinstall the wi fi chip. If this does not work you are in deep doo doo because the chip is fubar. I had the same issue with a Toshiba laptop but I returned it since it was a few days old. The chip is soldered to mo bo and unless you have real special tools and skills it cannot be removed.
