The new driver of the Atheros wireless Nic does not support "wireless bearer network"

As mentioned in the method for determining whether a wireless Nic supports "wireless bearer network", vwifibus is included in the driver file list of the wireless Nic in Windows 7. the sys file indicates that the driver supports the "wireless bearer network" function and can be used as a "soft AP.

After upgrading the wireless NIC driver on the computer today, I found that the "soft AP" function is unavailable. The specific phenomenon is that the "Microsoft Virtual WiFi Miniport Adapter" Virtual Nic no longer exists in the network connection, the "wireless bearer network" function cannot be enabled using commands.

The name mentioned before running prompts "Support for wireless bearer network", but the vwifibus. sys file is not in the file list:

It seems that the support is not necessarily accurate. It is more accurate to check whether the vwifibus. sys file exists in the driver file. This driver has passed WHQL certification, but should not have passed the Windows 7 logo certification.

The built-in driver of Windows 7 and the official driver of Atheros are also supported. Why is it not supported when this driver is installed today? Isn't the installation correct? After repeatedly uninstalling and restarting the computer, it still does not work.

Finally, I found a slightly old version of driver installed on the Internet, and it turned out OK. Originally, the version I downloaded9.1.0.100 not supportedAnd the previous version9.0.0.173 is supported:

Is such an important feature canceled in the new version after a version is released? Why can't I see some clues in the driver file? Open a one-to-one comparison between the inf files of two versions:

Originally, in the new driver version, a row was deleted:

Include = netvwifibus. inf

In this way, the virtual Wifi bus driver will not be installed when the driver is installed. I don't know why I want to cancel this function in the new version. I 'd like to use the old version. In the future, the driver will be updated with an extra eye.
