Modem stopped working after earlier Windows 10 update

Example: Pavilion P7-1254
Microsoft Windows 10 (64-bit)

Recently found that my exteran USB modem has stopped working while trying to send a FAX. It also will not work with the PhoneTray telemarketer blocking system. I then purchased a new Hiro external USB modem that is supposed to work with Windows 10, but it also does not work on my computer, but works fine on my wife's newer HP 400-314 computer. I have tried swapping ports to no avail. Seems the modem is able to read caller ID information, but does not respond to AT commands for on/off hook or dialing anymore.

Modem stopped working after earlier Windows 10 update

Are you getting any error message or code while trying to connect to a new a Modem?

Seeing no error messages whatsoever.

Is there any explanation or rex x mark on network icon next o clock icon?

Seeing nothing there.

Does your computer able to see New wireless modem?

The type of modem I am having issues with is a Hiro H50113 USB modem.

The computer recognizes the modem in multple programs (FAX, PhoneTray, VZ56K) and shows up fine in Device Manager but the modem is not responding to AT commands from the programs to go off-hook, on-hook, and dial, although several programs recognize caller ID information that is being sent by the modem.  I recently purchased a new Hiro H50228 USM modem that claims to be Windows 10 compatible, but it also is not working, but works fine on my wife's computer. I performed a modem query in device manager with the following results:

@Altair8800
Thank you for the information. 

  • Have you tried connecting to a wireless network modem or Mobile Hotspot? (not USB modem)
  • When you plug the Modem does your computer recognize the device?
  • Have you tried with all the USB ports?

While you respond to that, let's try these steps: 

Firstly, let's perform Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8.

Next stepBIOS default: 

  1. Turn off the computer and wait five seconds.
  2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
  3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
  4. Press F10 to Save and Exit.
  5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
  6. Follow the prompts to restart your computer.

Next step, Windows Update and HP Support Assistant:

To check for updates now, select the Start button, and then go to Settings  > Update & security  > Windows Update, and select Check for updates.

Install updates from HP Support Assistant: Go to Download HP Support Assistant to install the tool.

  1. To open HP Support Assistant, double-click the HP Support Assistant icon https://support.hp.com/doc-images/932/c05040382.jpg.
  2. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.
  3. Click Check for updates and messages to scan for new updates.
  4. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
  5. Click the update name for a description, version number, and file size.
  6. Select the box next to any updates you want to install, and then click Download and install.

Hope this helps! Keep me posted for further assistance.

Have you tried connecting to a wireless network modem or Mobile Hotspot? (not USB modem)

My computer connects fine to my wireless network.

When you plug the Modem does your computer recognize the device?

Yes, the modem is recognized by the computer and shows up in Device Manager as fully functional.

Have you tried with all the USB ports?

Yes, I have tested both USB modems on all USB ports

The link you suppled for a hard reset seems to only apply to laptop computers. Mine is a p7-1254

desktop. Is there a hard reset procedure that applies to this unit?

I will wait for your reply before I attempt the BIOS default

Thank you for the information. 

Disconnect all attached devices, such as printers, scanners, USB flash drive etc. Next, press and hold the power button for 20 to 30 seconds. 

Reconnect the keyboard and mouse then perform BIOS default.

Keep me posted for further assistance.

Echo_Lake:

Thanks for the suggestion.

I performed the BIOS reset after I also tried uninstalling/reinstalling all of the USB ports from the Device Manager.

Still seeing the same issue after the above procedures and retrying both modems on multiple USB ports.

Thank you for posting back. 

This sounds like a compatibility issue with the computer. maybe you can try with a different brand or Backward compatible device.
