Hi  @vivekcoool21 

Welcome to the HP Forum!

I understand that you suddenly lost your WiFi and you have the message :"No Networks Found" with a red cross on it. 

Please try the following by @Great-Deku-Tree:

First, we have a step by step guide to walk you through the troubleshooting process here:
Troubleshooting Your Wireless Network and Internet Connection

A second option, is to try these steps:
Power cycle the network:
1. Shut down your notebook.
2. Unplug the power to your router.
3. Unplug the power to your modem.
4. Wait at least 45 seconds.
5. Plug in the modem, and wait for it to come back online.
6. Plug in the router, and wait for it to come back online.
7. Turn on your notebook, and test your connection.

Disable the Power Off option for the adapter:
1. Open Device Manager. (Win Key+R > type devmgmt.msc > OK)
2. Expand the Network adapters.
3. Right-click on the Ethernet/Wireless Adapter and click Properties.
4. Click the Power Management tab.
5. Remove the check mark beside Allow the computer to turn off this device to save power.
6. Click OK.
7. Test.

Reset the TCP/IP settings on your PC:
1. Go to your start screen/menu and type CMD.
2. Right- click on the command prompt icon and chose Run as administrator.
3. In the window that opens type "netsh int ip reset resetlog.txt" without quotes, and press enter.
4. Restart your PC and test.

It may also help to reset the winsock catalogue:
1. Go to your start screen/menu and type CMD.
2. Right click on the command prompt icon and chose Run as administrator.
3. In the window that opens type "netsh winsock reset" without quotes, and press enter.
4. Restart your PC and test.

Reinstall the network adapter drivers:
1. Download the drivers from here but do not run them yet.
2. Go to your start screen/menu and type Device Manager.
3. Expand Network adapters.
4. Right click on the wireless adapter and choose Uninstall.
5. Run the downloaded drivers from step 1.
6. Restart your PC and test.

Test an ethernet connection:
Self- explanatory. Test if the issue persists on a wired connection to rule out the wireless adapter hardware so troubleshooting can be directed towards the right areas.

Test another connection:
Many people rule out their home network as an issue if another device is working on the same network. Networking is not that simple. Each device interacts differently with your router or modem and it is impossible to rule out settings in that device until the notebook has been tested on another network.

If those three steps do not resolve the issue, try this document published by Microsoft for networking issues: Wired and wireless network problems. You can change the operating system with the dropdown in the upper-right corner of the document.

Hopefully, this helps.

Hi @vivekcoool21 

Thank you for your reply,

Is the wireless card listed in Device Manger? Does it state it is working correctly? Did you  run a hardware test on the wireless card, if so what were the results?

HP Notebook PCs - Testing for Hardware Failures (Windows 10, 😎

If you run the Windows troubleshooter what are the results?

[vivekcoool21]

Yes the wireless card is listed in Device Manger.

Hardware changes scan doesn't show something and troubleshoot was unale to identify the problem.

Please help me, i am using Internet with Ethernet.

Hi, @vivekcoool21 

Thanks for the update.

When you tried to connect to a different network was there any change.  Would it be possible to try a wireless USB adapter to see it that works?  If warranty is not a concern, and you are comfortable with the process, you could try reseating the  wireless card.  Here is a link to the:

For removal procedures please note chapter 4, page 61 of the guide.

Please continue to let me know the results.

Hey,

As i told you earlier, WiFi is not showing any of the available network then how can i connect to different network.

And i had gone through the reseating the wireless card process but is very complex process so can't do this.

Please provide an alternate solution.

HI  @vivekcoool21 

Thank you for the reply.

Are you able to test with a wireless dongle.  If a wireless dongle works then it is the wireless card. 

[vivekcoool21]

It is only working with LAN / Ethernet Cable. Else with Wifi it is not showing any network available.

Can you please help in solving my issue?
