    About how to scan the network and how to list all the available networks, which API interface should i use?

    We are still investigating the 64-bit driver installation issue. Hopefully, this would get fixed soon.

    Is there any progress for 64-bit driver installation issue?

    I found Vista could not load the driver for the device after my laptop wake up from suspending || hibernation.

    I searched the HP official forum found many user have the same issue & have no solution to resolve.

  9. Do you have any solution to the 64-bit Win7 problem???

    Windows 7 was RTM-ed few days before today, and I would really like to use my expensive HP EliteBook 8530p HDSPA modem!!!

    Dear Program Manager,

    I follow your comment installed the Gobi undp1 driver and every thing seem fine. But when I closed and reopen the WWAN in the Wireless Assistant, the device was disabled.

    When I opened the Device Manager tried to enable the device, I could find only one device named "Qualcomm HS-USB QDLoader (COM8)" in the list, and the exception means Windows can not load the driver again.

    Even after the computer restart. the problem is still there.

    What should I do? Reinstall the drive follow the steps again? That’s terrible!

    Desire you can give me the solution to solve the problem completely.

    Thanks for your attention!

    Okay, so why is it that on some 6930p you see the device within Windows, The un2400 device.

    But on other 6930p it doesn't show in windows. But it's exactly the same kind of laptop.

    Product code and everything. All settings in the BIOS are also the same.

    and the slot is there to put the SIM in but it just doesn't work.

    No matter what Software you install or Drivers or updating the BIOS.

    So does any one know why?
