I have a Windows 10 1607(anniversary update) system Acer R5-471T. And my wifi card is
Qualcomm Atheros QCA61x4A Wireless Network Adapter. And I have the problem as stated. I am unable to connect to a network which is broadcasting on channel 13. And on Kali Live. I am able to connect that channel 13 networks.
So my card does support it. And I tried
updating the driver from official acer sites.
Nor does I have ad hoc settings on the device manager setting.
Nor does enabling and disabling wlan card works.
Changing country and region also didn't work.
And i am trying to fix the problem for a long time now. And I can't change the channel of Router to a range of 1-11.
Edit: I tried to configure it for another country with full restart. for fastboot restart. It didn't work.
