System check gives wireless module error

[UBSTUNG71-2]

Hello;

My wireless adapter stopped working overnight. Device manager shows the driver present but unable to start. I tried all the following:

1. reboot

2. network troubleshooter

3. Disable/enable Wi-Fi driver

4. Scan for HW changes

5. Check WLAN AutoConfig service running

6. Check for recent WIndows updates (none found)

I loaded the latest MediaTek MT7921 Wi-Fi driver. No difference in fact it doesn't even show up in Device manager anymore.

I then rebooted and ran a system Test. I got the following message.

"Wireless module check: NOT INSTALLED" 

What does this mean? I looked through all the BIOS settings and couldn't find any entry to enable this. Is this a hardware failure??

Thanks

Hi @UBSTUNG71-2,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

It sounds like you've been pretty thorough in troubleshooting the issue. If your system test is indicating that the wireless module is not installed, it suggests a hardware issue rather than a software one.

Here are a few additional steps you can take to confirm:

• Physical Inspection: If you're comfortable doing so, you might want to open up your laptop and physically inspect the wireless module. Ensure that it's properly seated in its slot and that there are no visible signs of damage.
• BIOS Settings: While you mentioned you couldn't find any relevant settings in the BIOS, it might still be worth checking if there's any option related to the wireless module. Sometimes, these settings can be under a different name or category.
• Hardware Failure: If all else fails, it's possible that there's indeed a hardware failure with the wireless module itself. In this case, you may need to have it replaced.

Since you've already tried updating drivers and checking for software-related issues, focusing on these hardware-related steps might help pinpoint the problem.

I hope this helps.

Take care and have a good day.
