How to perform hardware diagnostics

[gafurulkazi98]

HP ENVY x360

I cannot connect to WiFi.

I have contacted a representative at Windows and they have told me to check with HP to perform a hardware check to see if my Network Card is damaged.

I have read that a hardware diagnostics check can be run using HP PC Hardware Diagnostics for Windows and running a fast test in System Tests.

However, System Tests shows a blank page.

How do I perform the hardware diagnostic test to see if my network card is functioning properly?

Hi@gafurulkazi98, Welcome to the HP Support Community!

Here is a list of steps that commonly resolve issues with wireless connectivity.

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:
Powercycle 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 Network adapters.
3. Right-click on the Ethernet/Wireless Adapter and click Properties.
4. Click the Power Management tab.
5. Remove the checkmark 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 catalog:
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.

Hope this helps! Keep me posted.
