We can't figure out how to configure the RUT950 running on the new GUI (07.02.7) to use WLAN as WAN. There is not wlan0 interface selectable.
We did a workaround by downgrading to an older firmware that uses the old GUI. Configured the WLAN as WAN, saved settings and then upgraded again to 07.02.7 keeping the settings. After doing that, the router's interface list on the GUI showed a WWAN interface (type wireless). We can see in the settings that it uses wlan0 interface.
How can we setup WLAN as WAN on the new GUI?
