Thank you for posting on the HP Support Community.

  • Did this happen after a recent window or software update?
  • Did you make any changes in the settings of your PC prior to the issue?
  • Do you see red X or exclamation mark on the network icon?

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

Hard Reset: Follow steps from the link:

BIOS 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 and run the wireless test, 

Wireless Module test:

Use the following steps to open the Component Tests menu.

  1. Hold the power button for at least five seconds to turn off the computer.
  2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.
  3. On the main menu, click Component Tests.
  4. The Component Tests menu displays.
  5. Wireless Module Test - This test checks that the BIOS detects the wireless module and that it is enabled.

To run the test, click the Wireless Module, and then click Run once.

  1. The Wireless Module Test takes 30 seconds to complete.

Hope this helps! Keep me posted for further assistance.
