That was my problem. I didn’t expect the WISP mode in the Repeater configuration. For me Repeater Mode is extending an existing WLAN. The extended WLAN has the same SSID as the original WLAN.
In WISP mode there are two different WLANs with different SSIDs and the router routes the traffic between the two WLANS/networks in the same way as with a cable or a 3G/4G modem.
I flashed the firmware again (without keep settings) and everything is now working as expected. No need to install any protocols for WWAN.
Thanks to every relpyer and sorry for my late answering (was absent some days from home).
Have a nice day.
