3rd Generation, 64GB iPod Touch Not connecting to Wi-Fi

Does your Touch work on any wi-fi network? It would help rule out the device itself vs. a setting.

If you only have problem with this network, maybe try removing all security temporarily to see if you can get on at all. If so, then add security back one step at a time. Note that there are reports of problems where a network hides its SSID -- some devices won't have a problem with that, but some will. It is very ineffective security to hide the SSID anyway, so if that's an option I would let the router broadcast the SSID.

Try rockmyplimsoul's ideas first then if they dont work you should try reseting the device by going to:
Settings, general, then scrolling down to the bottom where it says reset, click reset and select "reset Network Settings"

Not familiar with how to set up an AE router, but if you're having trouble on other networks you might have a hardware problem with your Touch, or perhaps a software issue that might be corrected by Restoring (not resetting) the device.

If you Restore the Touch, you might try selecting the option to restore it as a new iPod (i.e. don't re-load your last backup in case that's where the problem lies). Restoring as a new iPod will mean having to re-do all your preferences, set up your networks, e-mail, etc. in addition to re-loading all your media, but sometimes that's what it takes.

Good luck!

I have had a similar situation and have talked at length with the Apple technicians to no avail. My ipod touch is a 3rd generation, 32 mg. and I've just installed an Airport Extreme base station. I can connect my iPod touch at my local coffee shop, but I couldn't connect at home. I've done all of the things to try to connect....resetting, reinstalling, all of it...and it still remained the same.

Finally, I have apparently hit on a solution! I enabled the Guest Network option on the Airport Extreme; my iPod touch recognizes it and voila! I am now connected!

dude try to do restore is be fix your problem!!! (he help me! )

When you restored your Touch, did you re-load your last backup or did you choose to set it up as a new iPod? If your last backup was corrupt in some way, then the problem would continue. Choosing to set it up as a new iPod at the end of the Restore process may help, but you'll not only have to re-load all your media you'll also have to re-enter all your preferences, network info, e-mail info, etc. etc. But if it solves your problem it would be worth the effort.
