Apple has finally responded to the iPad 3 Wi-Fi complaints piling up on the Apple Support forums. An internal memo posted by 9to5Mac shows Apple is "capturing" any new iPads suffering from slow Wi-Fi speeds and poor connectivity. This means Apple Store employees will replace any third-generation iPad experiencing Wi-Fi issues so they can send the defective device back to Apple for inspection.
If your iPad 3 is experiencing intermittent connectivity, slow Wi-Fi speeds, or it's not showing your Wi-Fi network you should take the device to your local Apple Store to see if they will replace it. The problem seems to be only affecting new iPads, not the iPad 2.
