Hi @JamoCenina,

Welcome to the HP Forums! 🙂 
I would like to take a moment and thank you for using this forum, it is a great place to find answers.

As I understand that the wifi function is not working on your PC.

I will be glad to help you with your HP Pavilion p6-2277d Desktop PC.

You can install the drivers for your wireless card from here.

You can follow the steps below.

Use the Network and Internet Troubleshooter (Windows 7).

• Right-click the wireless connection icon in the notification area, then select Troubleshoot problems. The Windows Network Diagnostic window opens and the troubleshooting process begins.
• Figure: Troubleshoot problems menu and wireless network icon.
• NOTE: This is an image of a connected network, your icon may look different depending upon the status.
• After automated troubleshooting has completed, read the information on the screen.
• This describes problems found, fixed, or actions necessary to resolve the connectivity problems.
• When complete, follow any recommended actions and try connecting again.

If the problem persists or there were no issues found by the troubleshooter, close the results screen and use this guided troubleshooter to further troubleshoot the issue.

Let me know how it goes.
