CollapseOverview

The Wi-Fi® enabled BlackBerry smartphone is unable to connect to the BlackBerry® Infrastructure using a Wi-Fi connection. The Wi-Fi diagnostic tool reports a failure under the BlackBerry Infrastructure heading.

CollapseCause

A network path to rcp.<carrier_region>.blackberry.com, where <carrier_region> is the region in which the wireless service provider is located (na for North America, eu for Europe, or ap for Asia/Pacific), cannot be established on port 443.

CollapseResolution

To determine whether other connections from the same network location can be established, complete the following steps:

  1. From a Windows® computer connected to the same network location as the Wi-Fi enabled BlackBerry smartphone, click Start.
  2. Click Run.
  3. Type cmd.
  4. Press Enter.
  5. Type telnet rcp.<carrier_region>.blackberry.com 443.

    Note: where <carrier_region> is the region in which the wireless service provider is located (na for North America, eu for Europe, or ap for Asia/Pacific)

  6. Press Enter.

The command should result in a blank screen with a flashing cursor. Any indication of connection failure means that the network connection is blocked.

Note: This test confirms network connectivity at a basic level. If the network prevents outgoing Secure Sockets Layer (SSL) or Transport Layer Security (TLS) traffic on port 443, contact the system administrator to allow this type of traffic. The BlackBerry smartphone requires a TLS connection to the BlackBerry Infrastructure.
