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

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.
