Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, to provide an accurate resolution, I need a few more details:

• Did this happen after a recent window or software update?
• Did you make any changes to the settings of your PC prior to the issue?
• When was the last time it worked fine?

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

1. From the Start screen, type device manager to open the Search charm, and then select Device Manager from the search results.

2. Double-click Network adapters.

3. Right-click the name of your wireless network adapter, and then select Uninstall.

4. When the Confirm Device Uninstall screen displays, click OK and wait for the device to be uninstalled.

   The name of the wireless adapter no longer shows in the network adapters category when it has been uninstalled.

5. At the top of the Device Manager window, click Action, and then select Scan for hardware changes.

   The computer reinstalls the wireless network and the wireless network adapter name is shown in the Network adapters category.

6. After the network adapter name appears in Device Manager, close Device Manager, and then restart the computer.

7. Try connecting to the Internet again. If problems persist, continue to the next step.

Restore BIOS settings for your computer to default settings:

1. Restart your notebook.

2. During startup, press F10 repeatedly until the BIOS menu displays.

3. Once the BIOS menu displays, press F9 to restore factory defaults.

4. Select Yes to confirm.

5. Press F10 to save changes and exit.

6. Select Yes to confirm.

   The computer restarts using the default settings.

Hope this helps! Keep me posted for further assistance.
