Ipod touch says not connected on wifi thing I click on it and it says searching for wifi but never finds it it popped up yesterday for like a min than went away but my computer and phone is connected to it what do I do?

Remove the wireless network from your iPod Touch then shutdown. Once you reboot add the wireless network back. If this dose not work try the Apple IOS wireless troubleshooting (http://support.apple.com/kb/TS1398)

Try resetting your internet and also when your not using things like your laptop turn in internet of that. That's what I done and it worked on my iPhone.
