Although some Intel® Wireless Adapters may come with this feature, they were not designed to support hotspots and Intel does not offer support for this feature and that may be the reason as to why you may encounter some difficulties while attempting to conntect. Does the adapter show problems only when you attempt to use it as a hotspot?
There are some events I found in the Event Viewer.
ID 5007, 5035, 5010,5002 and 5005 from NETwNs64, but all the description is
The description for Event ID XXXX(one of the IDs listed above) from source NETwNb64 cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
Intel(R) Dual Band Wireless-AC 3160
The specified resource type cannot be found in the image file.
And there are also some warnings from NDIS:
The network interface "Intel(R) Dual Band Wireless-AC 3160" has begun resetting. There will be a momentary disruption in network connectivity while the hardware resets.
Reason: The network driver requested that it be reset.
This network interface has reset 4 time(s) since it was last initialized.
If I just connect to Wi-Fi networks, it works normally. These only occur when I turn it on as a hotspot.
And I have tried some old drivers, but all of them didn't work.
Unfortunately we do not offer support for hotspot as our wireless adapters were not designed for this purpose. Please try to contact connectify and see if they have any workaround that might help. Please access this link: Hotspot - Connectify Knowledge Base
