I was setting up a wireless network for a new Asus laptop I just purchased, and instead of selecting my existing home network, I mistakenly set up a new one with my PC as the hub. My point of connection went from being "Home" to "My-PC_Network" and whenever I try to connect, it asks for a network security key that I don't have. I'm running Windows 7 and I've looked all over the web for a troubleshooting guide, but can't find anything that resembles my problem. Anyone know what I need to do?
