I just recently purchased a MacBook and have been trying to connect it to my old PC's Netgear WPN824v2 router. I've connected to the network via my WEP password. And on the Network preferences page it says that my Airport is connected to this network. However, when I try to open an internet page it says that there is no internet connection. Please help! I have no idea what to do in order to properly connect to the internet.
