BCM20702A0 Dell drivers for Windows 7 and Windows 8 [SOLVED!]

Q. Hello, I have a Dell laptop with an Unknown Device that has ‘BCM20702A0’ listed on it… do you know what driver I can download to to fix it? –Raymond K.

A. Here is the download link for the driver that should solve your BCM20702A0 Unknown Device issue:

mirror, Dell dl link

 

NOTE: after downloading the drivers you may need to select the ‘Extract without installing… >’ option first and then run the extracted driver setup program :-) Otherwise just pressing the initial ‘install’ button may give an error about Unable to find DUP value :-(

    Wow this had been bugging me for the past week so Thank You for the providing the driver that finally fixed my bcm20702a0 in device manager!

    • Hi Michael,
      Thank you for your comment. I am very glad the driver worked well for you!

      Have a great weekend. :-)

      Best regards,

        I had same download driver error problem, but downloading the driver from Dell did not solve the problem.

        On the driver pop-up box there is an option to ‘extract’ located at the bottom. I read somewhere to do an ‘extract’ first. This downloads the Broadcom bluetooth operating system software files into a new folder. I renamed it ‘Bluetooth’ so I could find it later, the I opened the .exe file and the Broadcom Bluetooth os started to download. I never got this far before.

        This is what was missing when my device was not detected.

        After the os downloaded, I went back to the same Dell bluetooth driver file and downloaded the driver. Everything is back to normal working.

        What a pain as no one ever mentioned the error was the lack of the Broadcom Bluetooth os system.

        • Hi Joe,
          Thank you for your comment and for the additional instructions you provided. I am very glad you got everything working!

          Have a great weekend,

      This is a crapware download trap. DO NOT USE ITY!

      • Hi Marty,
        Thank you for your comment. I am sorry that you encountered a problem with the download, could you have possibly clicked an advertisement instead of the hyperlinked download link?

        I ask because both the Dell download and the mirror are the correct drivers. They have been antivirus scanned and verified to work. However, I do not have any control over which advertisements play and one of those may have had something you did not want to download.

        I apologize for the inconvenience and I hope you have a great week!

        Best regards,
        -J.D.

  • Michael Henderson

    When I try to install this driver it fails, and I have tried it multiple times and rebooting and try and it still fails. I have a E5430 and I did blow it away and rebuild it and this is the only issue in the device manager?? In the device manager I have uninstalled it and tried to install drive still fails any help??

    Thanks

    MH

    • Hi Michael,
      Thank you for your comment. I am sorry to hear that this driver is not working for you.

      A few things:
      #1 How does the driver fail? (does the installer run? does it install but then not correct the issue? any particular error message displayed?)
      ++If the driver installer does not run, you may want to re-download the driver and try installing again
      #2 What version of Windows are you using?

      Hopefully with a bit more info we can figure out what is wrong!

      Best regards,
      -JD

        Thanks for the quick response!!
        when you run it, everything looks good with the Dell UPdate package for Wireless 380 Bluetooth Module v6.5 (A01) June 04, 2012 I have tried to just hit the install button then it come back with a “Failed to install” then I found someone else that said to extract without installing and have tried to update the driver from there and still no go.
        The installer runs it just fails
        I am on Windows 7 and when i flip the switch off on the wireless the BCM20702A0 goes away so I know it is the wireless piece. The files look ok as I was able to extract them all without installing and that succeeded. Arrghh

    OK I figured it out I had to download a cab file from Dell and extract the files and updated the driver from there and it is good now.

    Downloaded the driver and followed the instructions in post + comments. Bluetooth problem is finally fixed!!! Thanks everyone.

    Thanks for taking the time to post this, this has been bugging me for the last hour, until I found your post.
    Thanks again!

    • Hi Ara K,
      Thank you for your kind comment. I am very glad my page helped. :-)

      I am trying to keep my page as up to date as possible, could you let me know what model laptop you were installing the driver on and what OS you are using?

      Best regards and have a great day!
      -J.D.
