I have a home wireless network. All of the computers are running windows XP. I have a PSP that can connect. I also have a laptop with vista that can connect and I also have a MacBook. I entered the IPv4 information into the Mac manually, including IP, gateway, subnet, and DNS, but I can't connect to the network. It is a WEP secured network...do MACs have problems with that? Any suggestions would be great. Thank you.
