How to enable Genymotion emulator to use the WIFI internet the host is using

goto settings in the device and turn on the device wifi, in the android OS. You haven't mentioned it in your post I'm just covering the basic solutions here.

Simply choose the Host-only Adapter for Adapter 1 and NAT for Adapter 2. Make sure the cable-connected is selected(ticked). Host-only can be used to create a network containing the host and a set of virtual machines, without the need for the host's physical network interface. Instead, a virtual network interface (similar to a loopback interface) is created on the host, providing connectivity among virtual machines and the host.

This works for me. Hope it helps.

Try just turning on the WiFi in GenyMotion and selecting the WiredSSID.

I know this question been answered, but thought a picture would be easy to understand. Hope it helps.
