, similar to the "two-machine interconnection" in the wired network, although it can also achieve Internet sharing, but mainly used for two Devices are temporarily interconnected, and some devices (such as devices with Android) do not support connecting to a temporary wireless network.

Mode: Whether to enable the virtual Wifi NIC, disable to disallow, the virtual NIC will disappear.
