Hi, I have understood this question to mean that you wish to sync it with your computer. If this is correct then please follow the procedure below:
1. Connect iPod to computer and open iTunes 2. It will ask you whether it should sync it with the new computer removing all old data. Click Yes if you want to replace the content on the iPod from your iTunes library otherwise click No and proceed to next step. 3. If you want to keep the data then enable the check box Manually Manage Music and Movies 4. Click Apply
If the device has a passcode lock then you will need to restore ipod to its factory settings. This option too is on the main page of your device settings showing within itunes.

It has resett itself

Try resetting it while it is connected. Press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears.
If you have not already tried, I would also try the other ports on the computer.

Are you running iTunes 8?

And what kind of computer do you have?

well first u need to try restoring it on the computer and if is still wont connect then u may need to go on ur comp and go to the internet router settings and selet "add device or join new device"
