The iPod touch was disabled because the wrong password was entered too many times.

Connect the iPod to the computer you normally sync it with. After that you will be able to unlock it.

It depends on the severity and the settings you have given the iPod... Here's the full explanation. I would recommend reading the second paragraph first, but the solution if you really forgot your password is in the first paragraph.
If you cannot remember the passcode, you will need to restore your device on the computer that was used to originally sync the iPhone or iPod touch so that you can reset your passcode and resync the data from the device (or restore from a backup). If you restore on a different computer that was never synced to the iPhone or iPod touch, you will be able to unlock the device for use and remove the passcode but your data will not be present. Refer to "Updating and restoring iPhone and iPod touch software."

"If you enter the wrong passcode too many times, you'll see a message that says "iPhone is disabled" and to try again later. If you repeatedly enter the wrong passcode, iPhone or iPod touch will be disabled for longer intervals, before you can try again. After too many unsuccessful attempts, you won't be able to try again until you connect to the computer you normally sync with. Note that starting with iPhone 2.1 software, there is a setting to cause the device to erase itself after 10 consecutive incorrect password attempts. This setting is off by default. It  can be turned on by tapping Settings > General > Passcode Lock after you enter a correct passcode."

MY only solution was reset my i-pod touch, and after reset it's working very well my Wi-Fi.

To reset your i-pod touch just go to settings

Alternately, check your router to see if it actually sees the i-pod.

Try re-synching your i-pod.

Also try resetting your router with the i-pod off then after router resets turn i-pod back on. Should find then..

Hope this helps.
