BCM20702A0 Dell drivers for Windows 7 [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,

    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

    • 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
