Download only on wifi needs Ethernet option

Issue description: Yatse when opened in Android on ChromeOS has the option of connecting via Ethernet with wifi turned off.

The rationale for WiFi only is to not use mobile data. Maybe change the option to “Don’t download over mobile data”? That way wifi and Ethernet could be treated the same? Downloads can be much faster when over the LAN than when over wifi.

Please provide logs How to get debug information and open a proper issue Ethernet should already be treated as wifi.
