HP un2420 Mobile Broadband Driver Installation for Windows 10

How to get a un2420 Mobile Broadband Adapter to work in Windows 10

I recently upgraded a HP Probook 6540b Notebook from Windows 7 to Windows 10 and found that the un2420 Mobile Broadband Adapter was not working. It would show up in device manager with a warning icon next to it.

So first thing to do:

Install driver

So the first thing to do is to go and get the Windows 7 Pro driver for your notebook. In my case I went to the HP Probook 6540b support page  and downloaded the Qualcomm Mobile Broadband Drivers – Gobi2000


I then ran the executable. In HP’s case it will extract it into c:\swsetup\SPxxxxx by default and then install it automatically from there. It will fail.

Next thing to do is to go to the extracted directory (in my case C:\SWSetup\SP50377 )


Then go into the Qualcomm directory and right click on the GobiInstaller and select “Troubleshoot Compatibility”


Select Troubleshoot program




Select “test program”






If you go into Device Manager, you should now see the adapter successfully installed


Setting up Windows 10 to use it

Now with Windows 10, the HP Connection Manager just does not appear to work for this driver , or maybe even Windows 10?

Never mind, now that you see the adapter in device manage, just go here


and you will see you now have a cellular connection. Just right click on it and select connect. Up will pop up a settings window


Click on cellular



This should work on:

  1. I just tried do follow your steps, but even then the device shows up as “unknown device” with the yellow warning icon.
    I tried both packages sp50377 and sp53068.
    I got the HP 8540w Elitebook and unfortunatly upgraded to W10 recently.
    Any ideas what i can do ?

    • Hi,
      Try running the setup.exe using “troubleshoot compatibility” process and see what happens.
      Also you could try disabling UAC on your laptop temporarily, reboot it and try the install process again.
      The other thing to try is to select all 4 checkboxes and step through the resultant questions

  2. Thank you.

    I have an issue but not driver, all drivers seems correct without any warning, but the problem that keep show is “insert SIM” while actually I have SIM inserted and it working normally in phone.

    Anyone have this problem? any help please?

    • Seems there was an issue in SIM card slot, it was not able to read the sim card correctly so just make the sim card more thin so that metal attach with slot correctly and it working fine.

  3. Worked on EliteBook 8740w with SP53068.
    Thanks for the clue. This one is also biting my leg since W10 released 1 year ago.

  4. I use windows 8 and it worked like a charm, thank you. One thing I’m wondering though is how can I change network mode to 3G only?

  5. Worked on Probook 5320m using package SP53068, ex 2011 vintage drivers.
    I just ran C:\SWSetup\SP53068\Qualcomm\Setup.exe

    • Update to previous:
      Windows 10 build 15063
      – right click and run C:\SWSetup\SP53068\Qualcomm\Setup.exe via “troubleshoot compatibility”.
      – Select “Troubleshoot program”
      – Select first 3 check boxes the “Next”
      – Drivers should install OK.
      – Device Manager shows un2420 under the Ports category.

      • Update to above:
        Device Manager will show HP un2420 under Modems and under Network adapters and under Ports (one COM port for Diagnostics and one for NMEA)

  6. Hi,
    What could be the problem please? I have a 2560p but when trying to install it says gobi2000 device not found. Is there something I’m not doing correctly? I’d really appreciate your support.

  7. Hi Friends!
    I have 5101 and Windows 10
    After installing the modem drivers I could not turn on the gobi1000.
    I downloaded the HP Connection Manager. But he didn’t want to run in Windows 10:(.
    Then I unzipped his package and ran the MSI file as administrator.
    Everything works!
    I hope this helps some of you.

  8. Okay tried to the instructions from here with no luck. Don’t know what I am doing wrong installing on Elitebook 2470p, used the compatibility troubleshooter but still get exclamation in device manager, installing on Windows 10 1809.
