X220 Intel Wireless LAN driver 15.6.1 issue [ Edited ]

[Puppy]

I have updated to latest version 15.6.1 from 15.03.1000.163 (Windows 7 64 bit)

http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS015011

I have disabled virtual wifi hosted network by 'netsh wlan set hostednetwork disallow' command that always worked for previous driver versions. This version installed two adapters 'Microsoft Virtual WiFi Miniport Adapter' and 'Microsoft Virtual WiFi Miniport Adapter #2'  that appear in Device Manager and disabling the hosted network no longer works. The netsh disallow command reports ok but 'netsh wlan show hostednetwork' always reports Allowed state.

I have tried to remove the driver at all, restart and install it again but the issue persists. The only fix is to revert back to previous one 15.03.1000.163

I think this is a security issue that has to be resolved because the hosted network can not be safely disabled.

Hello,

Is it possible to disable this through the device properties in the Control Panel?

Yes, it is possible to disable both instances. I'm still not sure whether it is the right way to disable it. Something is broken and I would prefer to find what is the source of the issue.

The only reason I want to update to the recent version is that there is a "(Fix) Fixed a security vulnerability issue". If Lenovo could be more specific about the fixed issue I wouldn't have to consider the update.

According Intel support http://communities.intel.com/message/197143 "We have not had any reports about security vulnerability issues since driver version 9." Again, I'm wondering what security issue has been fixed (by Lenovo ?) ?
