One of my dad's computers won't connect to our wireless network which has a WPA2 encryption. After doing some looking around, I've determined that the wireless card just doesn't have the capability to connect to a WPA2 network. The more troubling problem is that even though the computer is directly connected to the router through an ethernet cord, it still can't access the internet. One other computer in the house is directly connected to the router and is able to access the internet. Any idea what the problem could be?
