The error message you are receiving indicates that the hosted network feature is not enabled on your computer. To fix this issue and create a wireless hotspot in Windows 10 using the Qualcomm Atheros AR9271 wireless network card, you can try the following steps:
1. Open the Command Prompt as an administrator. You can do this by pressing the Windows key, typing "cmd", right-clicking on "Command Prompt" and selecting "Run as administrator".
2. Run the following command to check if the hosted network feature is supported by your wireless network card:
```
netsh wlan show drivers
```
Look for the "Hosted network supported" line. If it says "No", it means your wireless network card does not support the hosted network feature and you won't be able to create a wireless hotspot. If it says "Yes", continue to the next step.
3. Enable the hosted network feature by running the following command:
```
netsh wlan set hostednetwork mode=allow ssid=myhome key=12345678
```
Replace "myhome" with the desired SSID (network name) and "12345678" with the desired network key (password). You can choose any values you prefer.
4. Start the hosted network by running the following command:
```
netsh wlan start hostednetwork
```
If successful, you should see a message saying "The hosted network started".
Now, you should have successfully created a wireless hotspot on your Windows 10 computer using the Qualcomm Atheros AR9271 wireless network card. You can try connecting your smartphone or other devices to the network using the SSID and network key you specified.
