@happy37 Welcome to HP Community!

I understand that the wireless is not working.

Do not worry. Let's work together and get this issue addressed.

Please provide the correct model number.

In the meantime, perform the below steps and check.

Use HP Support Assistant network diagnostics

HP Support Assistant is a software support diagnosis and troubleshooting tool from HP that can resolve many types of network and Internet connection issues.

NOTE: 

The images in this section might vary slightly from what you see on your screen.

To diagnose and troubleshoot network issues using HP Support Assistant:

1. If your computer has a wireless key or button on or near the keyboard and the wireless activity light is off or amber in color, and then press the key or button to enable your wireless adapter. This key might be the F10 key, F12 key or labeled with a symbol of an airplane.

   • If wireless activity comes on or the activity light turns blue, you have enabled wireless on your system. Try connecting to the Internet again. If problems persist, continue using these steps.

   • If your computer does not have a wireless key or the wireless activity lights remains off or orange, and then continue using these steps.

2. In Windows, search for and open HP Support Assistant.

   NOTE: 

   If HP Support Assistant is not installed on your computer, you can go to the HP Support Assistant website to download and install the HP Support Assistant software. If your computer cannot connect to the Internet, and then use Microsoft's Windows 8 automated network troubleshooting built into Windows 8 instead of this step.

3. In the My devices screen, select your device from the options listed.

   The My devices menu screen displays.

   

4. On the My devices menu screen, click Internet and Security.

   

5. Click HP Network Check.

   

6. If a User Account Control message opens, click Yes to allow the computer to make changes.

7. On the HP Network Check Welcome screen, click Next to run the network diagnostic.

8. If the diagnostic test finds no issues, close the windows and continue to the next section.

   If the diagnostic test finds one or more issues, continue with the steps in this section.

9. Click Possible Root Causes.

   

10. Click one of the tool icons for steps to resolve the issue, and then follow the on-screen instructions.

    

11. After completing the instructions, click Re-check.

    HP Support Assistant checks the network connectivity.

    

12. If necessary, repeat these steps until the network connectivity issue is resolved or all possible root causes and repairs have been completed.
