The BlackBerry smartphone user is unable to connect to a Wi-Fi network. One of the following error messages displays:

Unable to connect. Unknown error

Association failed

This issue is caused when media access control (MAC) address filtering is enabled on the Wi-Fi network, and the MAC address of the BlackBerry smartphone is not accepted.


To resolve this issue, add the MAC address of the BlackBerry smartphone to the accepted MAC address list for the Wi-Fi network.

Contact the system administrator of the Wi-Fi network, or see the product documentation for the wireless router for information on completing these steps.
