wifi disabled in my laptop

[zammil]

Hi guys. I bought a new hp-15r136ne laptop.its a windows 8.1.one of the network adapters is missing. I originally had two network adapters.but since my wifi was showing "limited connected", i tried updating the drivers and now only one driver is present. The driver name is "Realtek PCLe FE family controller #2".and the orange light in the button used for toggling airplane mode on/off is always ORANGE. There is actually no option for wifi in my connectivity. Only bluetooth is present.
