I have a Wifi iPad and for some reason now when I try to load the internet it says I have no connection. It is connected to my router, I can connect to my iPad via netatalk through Finder fine. Any ideas why? I wasn't doing anything unusual with it before hand. I tried going into the wifi settings and using a custom ip address (static) but that doesn't work. What should the subnet mask be?? 255.255.0.0 or 255.255.255.0 ??
