If your wireless service provider supports UMA, verify that your connection preference is not set to UMA-only.
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 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.
If you use EAP-TLS to connect to a Wi-Fi network, verify that you have added your authentication certificate to your BlackBerry®
device.
I cannot synchronize a certificate
Verify that the certificate synchronization tool of the BlackBerry® Desktop Manager is installed on your computer. If the certificate
synchronization tool is not installed on your computer, re-install the BlackBerry Desktop Software. For more information about installing
the BlackBerry Desktop Software, see the printed documentation that came with your BlackBerry device.
