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.
Note: Ensure that you have an appropriate BlackBerry data rate plan with AT&T.
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.
