Bluetooth Problems

  1. Hi, I'm sorry if I put this in the wrong forum but I'm not exactly sure where to stick this topic since I really don't know the problem.

    I have a 3DSP bluetooth/Wifi card in my computer. The bluetooth service works great after starting/restarting my computer, but it will not start up after waking from sleep mode. I have updated to the newest driver, but I still have the problems. I get no error messages from Windows or from the Bluesoleil program other than it just saying "The service is not available. Connection failed."

    I've also tried to manually restart the service by going into services.msc and that didn't work either, only seems to work if I completely restart the computer. So, I'm not sure if this is an issue with my card, my driver, or Windows (Vista). Does anyone have any idea what I should try?

    Any help you guys could give me would be greatly appreciated.

    What are the specs for your system?
    I have the same problem (only it's very rare) with my external HDD not starting, but I know it's a "lack of memory" issue. In your case, it may not be the bluetooth at all. Try running ccleaner and/or Advanced System Care to clean up your system and see if conditions improve.

    I have an AMD Phenom X4 940 (3.0 ghz), 4GB RAM (I don't remember the exact specs of the RAM, but I know it's DDR2), Windows Vista 64-bit.

    I'll run CCleaner and see what happens.

    I ran CCleaner and it made no difference.

    In general, there have been lots of problems with Power Management/Vista on 32 bit systems (let alone you have 64bit!)

    Are you running SP2? Do you have all the critical and hardware optional Windows updates installed?

    Yes, I am running SP2 and do have all updates installed. Anything I can do to try to resolve the issue?

    Also, not sure if this matters or not, but I forgot to mention that this problem just recently started. For the first month or so of having my bluetooth card I had no issues like this at all.

    Well, there's one thing that was true for most ethernet drivers (let's see if applies to your BT)

    Open Device Manager and find the BT driver under network adapters. If you rt click Properties, do you see a Power Management tab? if yes, uncheck the box for Allowing the computer to turn off the device to save power

    Nope, no power management tab. I did find something interesting tho, not sure what it means. But, in the General tab it says "This device is working properly" but in the Resources tab I get the message "This device isn't using any resources because it has a problem."

    Know any way I can try to find this problem?

    Go back to the General Tab. Look for the Device Status. Does it say working properly? Or does it have an error code?

    Just says it is working properly.

    I'm also having problems with my wifi not working after waking from sleep now, and when I try to go into the network and sharing center it just locks up.

    So, I tried reinstalling the drivers, but things just got worse.

    I now get a 1000007e BSOD when I try to shut down the computer and it has something to do with wltbus64.sys. I had this problem when I first installed my bluetooth/wifi card, but I reinstalled everything (including reseating the card) and the problem disappeared. But, since it came back, should I take this as a sign that this thing is not 100% compatible with my system?

    Anyone know of possible fixes for this?

    Try this to cleanup device manager entries... (not these instructions apply to Vista as well)

    Unplug your BT device

    See here to display all non-present device

    Then open Device Manager, click View->Show Hidden Devices

    Then look for all the Bluetooth entries, rt click uninstall and reboot
