Troubleshooting

I cannot connect to a wireless network

Try performing the following actions:

•Verify that your SIM card is inserted correctly.

•Verify that you have turned on the connection to the wireless network.

•If you were traveling and you selected a network manually, your BlackBerry® 8820 should remain connected to that network until you select your home network again.

I cannot connect to a Wi-Fi network

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 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.

•If you use EAP-TLS to connect to a Wi-Fi network, verify that you have added your authentication certificate to your BlackBerry® device.
