How can I fix this error?
I'm connected through Ethernet cable and my network adapter supposed to host the wireless network is the "Intel Dual Band Wireless-AC 8265",
whose driver is updated to the latest version (184.108.40.206),
running on an updated Windows 10 Home x64 v1803 operating system.
Thank you very much for your help.
EDIT: I just tried to connect to a WiFi network (instead of Ethernet) and then share the connection through a mobile hotspot and it worked! What could the problem be?
Thank you for joining this Intel Community.
Recent Intel® Wireless Adapters do not support the mobile hotspot connection you are describing. In this case, you can use the https://support.microsoft.com/en-us/help/4027762/windows-use-your-pc-as-a-mobile-hotspot Windows 10 Mobile hotspot.
Besides, the Intel® Wireless adapter in your system supports other features such as the new Windows 10 mobile hotspot feature via https://www.connectify.me/blog/features/what-is-wi-fi-direct/ Wi-Fi Direct.
I hope you find this information helpful.
