lost the internet connection when pc was reset

[yhuna42]

my computer has had a problem, it was turning on and off immediately by itself when i open it. i tried to fix it. i enter F10 button on the keyboard for PC Recovery. And the computer was reset. i can use the computer now but my problem is the internet connection was lost now.
i have my wireless internet connection before. how can i turn it back?

Have you tried to go into 'networking and sharing centre' then go to 'manage wireless networks' then 'Add' a network connection.
