automatic fail-over between ethernet and wifi port

Hi guys,

I would like to have an automatic fail-over in case the WAN(internet) on ether1 is not available and then to get the WAN from the Wifi port.
No problem to have one config to get the WAN from ether1 or to have a second config to get the WAN from the WiFi port, but all attempts to merge the two configs into one for a fail-over were unsuccessful. Also not able to configure a manual switch attempt as a first solution…

Any support from you how to configure an automatic (or at least manual) fail-over from ether1 to Wifi or vice versa is very appreciated.

Thanks for your quick response, anav.
Will read this in detail and then come back to the thread here.
