Hello, I'm having problems with my wifi for my ipod touch in certain cases. When I am in a wifi area, I USUALLY can connect to the internet. I look in settings>wi-fi and there will be an available connection labled "SETUP" (my neighbor's and in another instance, a friend's). I connect and get decent reception and it says I am connected, but when i go to an app. that uses the internet or the app. store or anything like that, i get an "invalid argument" message. If i go to safari, it says that it is loading the page but it never does! It just sits there forever... so can someone tell me how I could possibly fix this problem and connect to "SETUP"?
