How do I unlock my ipad 4?

The process is fairly simple.

• Choose the setting app on your iPad (the one with the gear icon).
• Choose Wi-Fi
• Make sure the Wi-Fi setting slider is green (on).
• click on your network name under "CHOOSE A NETWORK"
• enter your password (if necessary) for that network

Your network information will be saved and you will never have to enter that information again.

If you don't see your network, check to see if your router is working, and move closer to your wireless router to complete the settings

If you don't receive a wifi signal where you use your iPad, you might reposition your router, or move your iPad closer, or get a wifi repeater (like an Apple Airport Express) to extend your signal.

Of course. You first must be connected to the Internet via wi-fi or cellular connection (not all iPads have cellular). Once you have set that up (which is one of the first things you do when you set up an iPad), the Safari browser (the icon with the compass) and many (most?) apps connect to the Internet. Although you can look things up through the browser, many services have separate apps to perform their function, e.g. Yelp, Facebook. Apps like Weather retrieve their information from the Internet without having to go to a specific site, and apps like Notes sync your notes on the Internet (and may be available on your computer, as a result).

In fact, a large proportion of your activities on the iPad can't take place without a connection to the Internet.

Always a good idea to shut down and then turn back on (hold down both home button and power button until it turns all the way off. Wait a couple seconds, then press the power button to turn back on)

Try wireless again.

If nothing, then

Obviously check and make sure wifi is on under settings.

If still nothing,

Try resetting your network connections:
Settings > General, then tap Reset > Reset Network Settings

If you can't see any wifi networks at all, you might have a bad wifi card in the iPad. Bring back to an apple store.

check the model nr. on the back side:
