Failover with WAN and Mobile works out of the box. But how can I add a WLAN connection to the failover?
I setup WLAN as client, at Status -> Network -> Wireless I have a new Wireless Interface with the SSID of the WLAN Network I connected. Mode is Client and Status green "running". Then I enable this new Interface at Network -> Failover. But if I disconnect WAN and remove the SIM-Card, I got no connection. Is there a step by step guide?
