I turned on my laptop yesterday and there is no wifi option on my laptop. I can use Ethernet and in Device manager in network adapters it only detects an Ethernet driver which is Realtek PCIe FE Family Controller and nothing else. Wifi is working fine on Phone, iPad and PS3. I tried doing a system restore and that did nothing. I tried installing some driver and that did nothing. What is going on? My laptop is a HP Pavillon 15-P015TX and i've had the laptop for almost a year.
