Hi CaptainPlanet,

Are you trying to connect to your own wireless network? If so, is your network secured with WEP, WPA or WPA2?
You may find out the Security key from your router's wireless setting page.

You might want to remove all your wireless network profiles then re-add your own Wi-Fi connection manually, here's how. Make sure that you enter the correct security key.

Please post an update.
