Cannot automatically connect to a mobile broadband network after you unblock a PIN-based mobile broadband device in Windows 7 or Windows Server 2008 R2


View products that this article applies to.

Symptoms

Consider the following scenario:
  • You set a mobile broadband network profile to automatically connect on a computer that is running Windows 7 or Windows Server 2008 R2.
  • You connect a personal identification number (PIN)-enabled mobile broadband device to the computer, or you enable an embedded PIN-based mobile broadband device on the computer.
  • You click the Connect to a Network icon in the notification area on the right side of the taskbar.
  • In the list of available wireless networks, you select the mobile broadband connection, and then you click Connect.
  • When you are prompted to enter a PIN code to unblock the mobile device, you type a correct PIN code.
In this scenario, the computer does not automatically connect to the mobile carrier network as expected.

Notes
  • If you unblock the mobile network device by typing the correct PIN code before you set the mobile broadband network profile to automatically connect, the computer registers and connects to the mobile carrier network.
  • If you detach a non-embedded mobile broadband device, and then reattach it after you unblock the device by typing the correct PIN code, the computer registers and connects to the mobile carrier network.

  • The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:
    VersionProductMilestoneService branch
    6.1.760 0.17xxxWindows 7 and Windows Server 2008 R2RTMGDR
    6.1.760 0.21xxxWindows 7 and Windows Server 2008 R2RTMLDR
    6.1.760 1.17xxxWindows 7 and Windows Server 2008 R2SP1GDR

Workaround

To work around this issue, remove the detachable mobile broadband device, unblock the device by using the PIN code, and then reattach the device to the computer. After you do this, the computer connects to the network automatically. Or, you can change the autoconnect setting of the mobile broadband network profile from Always to Only when not roaming. After the computer connects to the network, you can reset the autoconnect setting to Always.
