Try performing the following actions:

•Verify that you have turned on the connection to the Wi-Fi® network.

•Verify that you are in a Wi-Fi coverage area.

•If the Wi-Fi network does not appear in the Setup Wi-Fi application and you know the network name, connect to the Wi-Fi network manually.

•Verify that the connection options in the Setup Wi-Fi application are correct. If you have already verified these options, verify that the advanced connection settings for the Wi-Fi network are correct.

•If you switched Wi-Fi networks manually, switch to another Wi-Fi network or set your device to scan for available Wi-Fi networks.

•If your wireless service provider supports UMA, verify that your preferred network type is not set to WAN-only.

•If you use PEAP, EAP-TLS, EAP-FAST, EAP-TTLS, or EAP-SIM to connect to a Wi-Fi network, verify that you have installed the root certificate for the certificate authority server that created the certificate for the authentication server.
