You have set a proxy
Android tries to connect to google.com at boot.
If this connection fails, Android considers that there is no Internet connectivity.
To fix this, unset your proxy and reboot the device.
Also, make sure to unset your proxy before stopping your device to avoid this problem in the future.

You are using quick boot (Genymotion Desktop - QEMU only)
This bug can occur after a quick boot.
Try launching the device with a cold boot instead.
For more information, see Genymotion Desktop on-line documentation.
You are in China
If you are in China, Wifi will probably be disabled when you start your device.
Genymotion devices try to connect to google.com at boot to verify the Internet connection.
Due to restrictions in China, the Internet verification test fails, and the device thinks that Internet is not connected.
Genymotion Desktop
To solve this problem, use a VPN on the host computer and connect to a non-Chinese network.
Alternatively, use the following method.
1. Open a terminal and run the following ADB commands:
``
adb shell settings put global captive_portal_http_url https://www.google.cn/generate_204
adb shell settings put global captive_portal_https_url https://www.google.cn/generate_204
adb shell settings put global ntp_server 1.hk.pool.ntp.org
``
2. Reboot the device.
Wifi should then be available.
For more information about ADB usage with Genymotion, please refer to Genymotion Desktop documentation.
