My cousin just called about 10 minutes ago saying her PC won't connect to their wireless network. I didn't have the patience to talk to her much so I said I would go over tomorrow to fix it. The only thing that she said was that the PC says the adapter is unplugged when she goes to her network status. I'm just wondering what should I do?
 
If it says uplugged, it is reffering to the network cable connection, not wireless.
