Closing an aethercast session does not restore Wifi connection

On a BQ M10 tablet, aethercast (which unfortuntely only works with a work-around, see https://bugs.launchpad.net/aethercast/+bug/1590135/comments/8) does not restore the Wifi connection after the screen share was disconnected. In order to get WiFi back, one has to manually turn off and on the Wifi connection.

How to reproduce:
1. Establish a screen share session via aethercast (using the work-around https://bugs.launchpad.net/aethercast/+bug/1590135/comments/8 on a BQ M10)
2. Disconnect the screen share session by clicking on the name of the connected display in order to disconnect
3. Open the webbrowser of the tablet and try to open any webpage
-> There will be not Wifi working!
4. You have to manually disable Wifi connection and manually connect to Wifi again. Then you have again access to the internet.
