Whats wrong with my internet connection

Have you tried turning off wireless security temporarily in the router ?

What happens when you connect the computer to the router using an ethernet cable ?

I am not using an ethernet cable to connect to the router. The laptop is wifi and has a wireless connection. I just am having a problem getting a wireless connection again under network connections. It was there and somehow it got deleted
 
Yes, but what happens when you use an ethernet cable ?

The reason I ask is it might help isolate whether the problem lies in the router or at the computer.
