Windows 10: Windows 11 Wi-Fi software stack / architecture

I am planning to develop a Wi-Fi miniport device driver for Windows 11 for a 802.11ax chip-set based PCIe card. I have worked on NDIS based Wi-Fi miniport device driver in the distant past. I came across Windows Wi-Fi software stack / architecture diagram at docs.microsoft.com, which is based on WDF. But I am confused about role of each of the software components nWiFi, WiFiCx, WLANSVC of Windows 11 Wi-Fi software stack. How does the whole Wi-Fi software stack work in Windows 11? More specifically, what does WiFiCx software component do? What does nWiFi software component do?

USB Wi-Fi Adapter Disabling

Is it on Windows 8's compatibility list (check MS website- forgot link)?

I had an issue with one Wi-fi adapter and it wasn't listed as compatible- All was well when I swapped it out with one on the compatibility list

 

Windows 10 and no wi-fi

Hi Joachim,

Thank you for posting your query in Microsoft Community. Appreciate your interest in using Windows 10.

I would suggest you to follow the methods below:

Method 1: Run the Hardware and Device troubleshooter by following the steps below:

• Click on the Start button, and type “Troubleshooting” on the search bar.
• Click on troubleshooting, then click on “Hardware and sound”.
• Under Hardware and sound, click on “hardware and devices”.
• A pop-up will appear, click on the “Next” button and your hardware troubleshooting will start.

Method 2: The issue may occur if the drivers for Wi-fi are not installed or updated. I suggest you to install/update the latest version for Wi-fi drivers by following the steps below.

• Press ‘windows key + R’ and type ‘devmgmt.msc’ and press Enter.
• Expand ‘Network adapter’ and right click on Wi-fi driver and select update.

Hope the information is helpful. Feel free to

Trouble Changing Wi-Fi Password


I've been following the following steps to change my Wi-Fi password for some time:

1. Launch Control Panel.
2. Click "Network and Internet."
3. Click "Network and Sharing Center."
4. Click "Wi-Fi...."
5. Click "Wireless Properties."
6. Click the Security tab.
7. Check "Show characters."
8. Enter the password in "Network security key."

Those steps have been working just fine, but today I discovered a new wrinkle. If I change the password inside the router first, "Wi-Fi..." doesn't appear in step 4. This isn't much of a problem at home, because I can just change the password in Control Panel before I change it inside the router, but it would be a problem at a public hotspot, or something of that nature. I also tested Brink's instructions in "How to Connect To a Wireless Network in Windows 10," but they don't work for me either. How can I fix this?
