Wireless stopped working on my laptop

I was using the internet on my laptop and the conection went off for a few seconds. After that, I couldn't access the router anymore, not even by cable. So I tried, te basic turn it on and off and I could access it by cable, but the wireless is still not working on my laptop. I checked if the wireless board was properly configured and everything seems alright.
I think the problem is on the laptop because the wireless works on my phone and tablet!
 
Is there by chance a switch you might of accidently flipped or a set of keys you accidently touched that tripped it?
 
What OS do you have? You need to get to 'network adaptors' page and tell us what is shown.
