Well, there could be many reasons for this, and its kind of hard to narrow it down with th lack of info but there are a few things you can try.
- Make sure you are not in airplane mode.
- If not, go into network settings on your ipod and click "forget network". Then re-establish a connection with that network and type the password(found on your router, usually called the WEP key) if need be.
- Try resetting you network settings. go to settings-general-reset and network settings, wich will refresh your wifi.
- If that doesnt work, try resetting your router. then ty it out.
If none of this works, try to reset the ipod. Good luck!
You are not giving much information Maybe:
If not successful, an appointment at the Genius Bar of an Apple store is usually in order.
Does the iPod connect to other networks?
Does the iPod see the network?
Any error messages?
Do other devices now connect?
Did the iPod connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on the router
- Reset network settings: Settings>General>Reset>Reset Network Settings
- Restore from backup. See:
- Restore to factory settings/new iOS device.
If still problem make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.
