Windows did not detect any networking hardware

[x_ile]

My system can no longer detect a network adapter. In Device Manager > Network adapters, I have 8 WAN Miniport Devices plus the temporary USB wi-fi device I'm using to connect here. The pre-installed (Intel Wireless LAN?) is no longer listed.

Control Panel > Network and Internet > Network and Sharing Center > Set Up a New Connection or Network > Connect to the Internet says:  Windows did not detect any networking hardware.

Settings > Network & Internet > Troubleshoot says: Install a driver for your network adapter.

HP Support Assistant > Troubleshooting and fixes > Network Check says: Driver missing or hardware issue (103).

I have downloaded & installed the latest drivers (sp74466.exe). On completion it opens a CMD window (attrib +h C:\system.sav /s /d), which stays open and blank before opening a dialog box that says: All installations completed, please refer to the log file for details. (OK).

I also have an application called WiFi_20.30.1_PROSet64_Win10.exe. Not sure if I need it, but it was created around the same time I had this exact problem before. I'm strongly suspecting a hardware failure, but I'll try anything suggested (even an OS refresh).

Thank you,

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 windows is not detecting the networking hardware,

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

Have you installed a retail copy of windows or Did you use the HP Recovery media?

(Use this article to obtain an HP Recovery Media to reinstall the OS as it should resolve all driver related issues, if you haven't used it already: http://hp.care/2qP2Lqh )

While you respond to that, here's what you need to do:

If you've already reinstalled the drivers and the OS (Usually the last resort), I recommend you run an extensive hardware test to identify and resolve the issue accordingly:

If the HP PC Hardware Diagnostics for Windows app is not available on your computer, download the latest version from the HP Hardware Diagnostics website.

1. In Windows, search for and open the HP PC Hardware Diagnostics Windows app.

2. On the main menu, click System Tests.

3. Click the System Extensive Test tab.

4. Click Run once.

   While the test is running, the time remaining and test result for each component are shown on the screen. The test can take 2 or more hours to complete.

5. If a component fails a test, write down the failure ID (24-digit code) so you have it available when you contact HP Customer Support. The information is also available in Test Logs on the main menu.
