I was removing a wifi network and after removing it, my wifi icon is blank, showing a cross over it, while i hover over it which says Not Configured, I googled the problem but didn't find any solution to the problem, I tried reinstalling mavericks, while everything (user, setting and everything remain same) the problem remain same too. What can be the problem? How can I fix it? and
Rather than removing a Wi-Fi network, it appears you've removed the Wi-Fi service. In OS X prior to 10.10, this means the AirPort shows Not Configured.
To allow configuration of AirPort, you need to add the Wi-Fi service back to the list of services:
Go to System Preferences → Network and click the + button to add a service.
Select Wi-Fi as the Interface and provide a service name.
This will allow configuration through the menu bar item.
As even after installation, your hardware is not functioning, then it certainly HS. Do an Apple Hardware Test in advance mode (could take time)
